MC9S12XS128MAA

The MC9S12XS128MAA is a 16-bit Microcontroller based on enhanced HCS12X CPU with CISC architecture operates at a maximum frequency of 40MHz. The device incorporates 128kB internal flash, 8kB internal RAM, 8kB EEPROM, 8-channel 12-bit A/D converter and 59 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.
