4.2 FlexMemory
Freescale’s new FlexMemory technology provides an extremely versatile and powerful solution for designers seeking on-
chip EEPROM and/or additional program or data flash memory. As easy and as fast as SRAM, it requires no user or system
intervention to complete programming and erase functions when used as high endurance byte-write/byte-erase EEPROM.
EEPROM array size can also be configured for improved endurance to suit application requirements. FlexMemory can also
provide additional flash memory (FlexNVM) for data or program storage in parallel with the main program flash.
The key features of FlexMemory include:
• Configurability for designer:
• EEPROM array size and number of write/erase cycles
• Program or data flash size
• EEPROM endurance of 10M write/erase cycles possible over full voltage and temperature range
• Seamless EEPROM read/write operations: simply write or read a memory address
• High-speed byte, 16-bit, and 32-bit write/erase operations to EEPROM
• Eliminates the costs associated with external EEPROM ICs, and the software headaches and resource (CPU/flash/
RAM) impact of EEPROM emulation schemes
• Storage for large data tables or bootloader
• Read-while-write operation with main program flash memory
• Minimum write voltage 1.71V
4.2.1 Programmable Trade-Off
FlexMemory lets you fully configure the way FlexNVM and FlexRAM blocks are used to provide the best balance of
memory resources for their application.
The user can configure several parameters, including EEPROM size, endurance, write size, and the size of additional
program/data flash.
Features
K50 Family Product Brief, Rev. 8, 5/2011
Freescale Semiconductor, Inc. 7
In addition to this flexibility, FlexMemory provides superior EEPROM performance, endurance, and low-voltage operation
when compared to traditional EEPROM solutions.
• Enhanced EEPROM — Combines FlexRAM and FlexNVM to create byte-write/erase, high-speed, and high-endurance
EEPROM
• FlexNVM — Can be used as:
• part of the EEPROM configuration,
• additional program or data flash, or
• a combination of the above. For example, a portion can be used as flash while the rest is used for enhanced
EEPROM backup.
• FlexRAM — Can be used as part of the EEPROM configuration or as additional system RAM
4.2.2 Use Case Example
The MCU has 128 KB program flash, 32 KB SRAM, and FlexMemory has 128 KB FlexNVM and 4 KB FlexRAM
(maximum EEPROM size). The application requires 8 KB additional program flash for a bootloader and 256 bytes of high-
endurance EEPROM. The user allocates 8 KB of FlexNVM for the additional program flash and the remaining 120 KB for
EEPROM backup.
The user defines 256 bytes of EEPROM size from the FlexRAM. In this example, the EEPROM endurance results in a
minimum of 2.32M write/erase cycles.

24 Freescale Semiconductor, Inc.
4.5 Module-by-module feature list
The following sections describe the high-level module features for the family's superset device. See the previous section for
differences among the subset devices.
Core modules
4.5.1.1 ARM Cortex-M4 Core
• Supports up to 100 MHz frequency with 1.25DMIPS/MHz
•ARM Core based on the ARMv7 Architecture & Thumb®-2 ISA
•Microcontroller cores focused on very cost sensitive, deterministic, interrupt driven environments
• Harvard bus architecture
• 3-stage pipeline with branch speculation
• Integrated bus matrix
• Integrated Digital Signal Processor (DSP)
• Configurable nested vectored interrupt controller (NVIC)
• Advanced configurable debug and trace components
• Embedded Trace Macrocell (ETM)
4.5.1.2 Nested Vectored Interrupt Controller (NVIC)
• Close coupling with Cortex-M4 core's Harvard architecture enables low latency interrupt handling
•Up to 120 interrupt sources
• Includes a single non-maskable interrupt
• 16 levels of priority, with each interrupt source dynamically configurable
• Supports nesting of interrupts when higher priority interrupts are activated
• Relocatable vector table
4.5.1.3 Wake-up Interrupt Controller (WIC)
• Supports interrupt handling when system clocking is disabled in low power modes
• Takes over and emulates the NVIC behavior when correctly primed by the NVIC on entry to very-deep-sleep
• A rudimentary interrupt masking system with no prioritization logic signals for wake-up as soon as a non-masked
interrupt is detected
• Contains no programmer’s model visible state and is therefore invisible to end users of the device other than through
the benefits of reduced power consumption while sleeping
4.5.1.4 Debug Controller
• Serial Wire JTAG Debug Port (SWJ-DP) combines
• external interface that provides a standard JTAG or cJTAG interface for debug access
• external interface that provides a serial-wire bidirectional debug interface
• Debug Watchpoint and Trace (DWT) with the following functionality:
• four comparators configurable as a hardware watchpoint, an ETM trigger, a PC sampler event trigger, or a data
address sampler event trigger
4.5.1
Core modules
K50 Family Product Brief, Rev. 8, 5/2011
Freescale Semiconductor, Inc. 25
• several counters or a data match event trigger for performance profiling
• configurable to emit PC samples at defined intervals or to emit interrupt event information
• Instrumentation Trace Macrocell (ITM) with the following functionality:
• Software trace - writes directly to ITM stimulus registers can cause packets to be emitted
• Hardware trace - packets generated by DWT are emitted by ITM
• Time stamping - emitted relative to packets
• Embedded Trace Macrocell (ETM) supports instruction trace
•CoreSight™ Embedded Trace Buffer (ETB) is a memory-mapped buffer to store trace data. Allows reconstruction of
program flow with standard JTAG tools.
• Test Port Interface Unit (TPIU) acts as a bridge between ITM or ETM and an off-chip Trace Port Analyzer
• Flash Patch and Breakpoints (FPB) implements hardware breakpoints and patches code and data from code space to
system space
System modules
4.5.2.1 Power Management Control Unit (PMC)
• Separate digital (regulated) and analog (referenced to digital) supply outputs
•Programmable power saving modes
• No output supply decoupling capacitors required
• Available wake-up from power saving modes via RTC and external inputs
• Integrated Power-on Reset (POR)
• Integrated Low Voltage Detect (LVD) with reset (brownout) capability
• Selectable LVD trip points
• Programmable Low Voltage Warning (LVW) interrupt capability
• Buffered bandgap reference voltage output
• Factory programmed trim for bandgap and LVD
• 1 kHz Low Power Oscillator (LPO)
4.5.2.2 DMA Channel Multiplexer (DMA MUX)
• 16 independently selectable DMA channel routers
• 4 periodic trigger sources available
• Each channel router can be assigned to 1 of 64 possible peripheral DMA sources
4.5.2.3 DMA Controller
• Up to 32 fully programmable channels with 32-byte transfer control descriptors
• Data movement via dual-address transfers for 8-, 16-, 32- and 128-bit data values
• Programmable source, destination addresses, transfer size, support for enhanced address modes
• Support for major and minor nested counters with one request and one interrupt per channel
• Support for channel-to-channel linking and scatter/gather for continuous transfers with fixed priority and round-robin
channel arbitration
4.5.2.4 Watchdog Timer (WDOG)
• Independent, configurable clock source input
4.5.2
System modules
K50 Family Product Brief, Rev. 8, 5/2011
26 Freescale Semiconductor, Inc.
• Write-once control bits with unlock sequence
• Programmable timeout period
• Ability to test watchdog timer and reset
• Windowed refresh option
• Robust refresh mechanism

5 Power modes
The power management controller (PMC) provides the user with multiple power options. All together 10 different modes of
operation are supported to allow the user to optimize power consumption for the level of functionality needed.
Depending on the stop requirements of the user application, a variety of stop modes are available that provide state retention,
partial power down or full power down of certain logic and/or memory. I/O states are held in all modes of operation. The
following table compares the various power modes available.
For each run mode there is a corresponding wait and stop mode. Wait modes are similar to ARM sleep modes. Stop modes
(VLPS, STOP) are similar to ARM sleep deep mode. The very low power run (VLPR) operating mode can drastically reduce
runtime power when the maximum bus frequency is not required to handle the application needs.
The three primary modes of operation are run, wait and stop. The WFI instruction invokes both wait and stop modes for the
chip. The primary modes are augmented in a number of ways to provide lower power based on application needs.

Figure 5. MQX Comprehensive Solution
Key benefits of Freescale's MQX RTOS include:
•Small memory footprint: The RTOS was designed for speed and size efficiency in embedded systems. It delivers true
real-time performance, with context switching and low-level interrupt routines hand-optimized in assembly.
• Component-based architecture: Provides a fully-functional RTOS core with additional, optional services. Freescale's
MQX RTOS includes 25 components (8 core components and 17 optional). Components are linked in only if needed,
preventing unused functions from bloating the memory footprint.
• Full and lightweight components: Key components are included in both full and lightweight versions for further control
of size, RAM/ROM utilization, and performance options.
• Real-time, priority-based, preemptive multithreading: Allows high-priority threads to meet their deadlines consistently,
no matter how many other threads are competing for CPU time.
• Scheduling: Enables faster development time by offloading from developers the task of creating or maintaining an
efficient scheduling system and interrupt handling.
• Code reuse: Provides a framework with a simple, intuitive API to build and organize the features across Freescale’s
broad portfolio of embedded processors.

• Fast boot sequence: Ensures the application is running quickly after the hardware has been reset.
• Simple Message Passing: Messages can be passed either from a system pool or a private pool, sent with either urgent
status or a user-defined priority, and broadcast or task specific. For maximum flexibility, a receiving task can operate
on either the same CPU as the sending task or on a different CPU within the same system.
