The MC9S12XF512MLM is a 16-bit Microcontroller based on enhanced HCS12X CPU with CISC architecture operates at a maximum frequency of 50MHz. The device incorporates 512kB internal flash, 32kB internal RAM, 4kB EEPROM, 16-channel 12-bit A/D converter and 91 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 two serial peripheral interface modules (SPI). The MC9S12XF family features the performance boosting enhanced XGATE co-processor. The XGATE is programmable in C language and runs at twice the bus frequency of the S12. The XGATE instruction set is optimized for data movement, logic and bit manipulation instructions.
