Overview
●The S12XE family of MCUs takes the S12XD family a step further with features that deliver enhanced system integrity and greater functionality, including:
● Memory protection unit (MPU)
● Error correction code (ECC)
● Enhanced EEPROM functionality
● Enhanced XGATE
● Frequency-modulated locked loop
● Faster analog-to-digital converter (ADC)
●Additionally, the S12XE family:
● Extends the S12X product range up to 1 MB of flash memory with increased I/O capability in the 208-pin version of the flagship MC9S12XE100
● Delivers 32-bit performance with all the advantages and efficiencies of a 16-bit MCU
● Is optimized for automotive multiplexing, generic auto body and industrial applications
