4.2 FlexMemory
Freescale’s new FlexMemory technology provides an extremely versatile and powerful solution for designers seeking onchip 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.
In addition to this flexibility, FlexMemory provides superior EEPROM performance, endurance, and low-voltage operation
when compared to traditional EEPROM solutions.

Features
• 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 highendurance 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.

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.
Table 5. Chip power modes
Chip mode
Description
Normal run
Allows maximum performance of chip. Default mode out of reset; onchip voltage regulator is on.
Normal Wait via WFI
Allows peripherals to function while the core is in sleep mode,
reducing power. NVIC remains sensitive to interrupts; peripherals
continue to be clocked.
Normal Stop via WFI
Places chip in static state. Lowest power mode that retains all
registers while maintaining LVD protection. NVIC is disabled; AWIC is
used to wake up from interrupt; peripheral clocks are stopped.

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.

Freescale Semiconductor, Inc.
Developer Environment
• 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.
