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 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/
• Storage for large data tables or bootloader
• Read-while-write operation with main program flash memory
• Minimum write voltage 1.71V
