The MC9S12XS64CAE is a 16-bit Microcontroller based on enhanced HCS12X CPU with CISC architecture operates at a maximum frequency of 40MHz. The device incorporates 64kB internal flash, 4kB internal RAM, 4kB EEPROM, 8-channel 12-bit A/D converter and 44 general-purpose I/O pins. This device also features peripherals like one multi-scalable controller area networks (MSCAN) CAN 2.0 A/B software compatible module, two serial communications interface (SCI) and one serial peripheral interface modules (SPI). The MC9S12XS family retains many of the features of the S12XE family including error correction code (ECC) on flash memory, a separate data flash module for code or data storage, a frequency modulated locked loop (IPLL) that improves the EMC performance and a fast A/D converter.
