S12XE

Roll over image to zoom in

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
