MC9S12XS128MAA Description
The MC9S12XS128MAA is a 16-bit microcontroller with CISC architecture that operates at a maximum frequency of 40MHz. The device has 128kB of internal storage, 8kB of internal RAM, 8kB of EEPROM, an 8-channel 12-bit A/D converter, and 59 general-purpose I/O pins. The MC9S12XS128MAA also includes peripherals like a CAN 2.0 A/B software compatible multi-scalable controller area networks (MSCAN) module, two serial communications interface (SCI) modules, and one serial peripheral interface module (SPI). Many of the characteristics of the S12XE family are retained in the MC9S12XS family, such as error correction code (ECC) on flash memory, a separate data flash module for code or data storage, a frequency modulated locked loop (IPLL) that increases EMC performance, and a fast A/D converter.
