MC9S12XDT512CAA

The MC9S12XDT512CAA is a 16-bit Microcontroller based on enhanced HCS12X CPU (40MHz bus) with CISC architecture operates at a maximum frequency of 80MHz. The device incorporates 512kB internal flash, 20kB internal RAM, 4kB EEPROM, 8-channel 10-bit A/D converter and 59 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module, five multi-scalable controller area networks (MSCAN) CAN 2.0 A/B software compatible modules, two serial communications interface (SCI) and three serial peripheral interface modules (SPI). The MC9S12XD family features the performance boosting XGATE co-processor. The XGATE, which is programmable in C language, has an instruction set which is optimized for data movement, logic and bit manipulation instructions. It runs at twice the bus frequency of the S12X and off-loads the CPU by providing high speed data transfer between any peripheral module, RAM and I/O ports.
