MC9S12E256CPVE

The MC9S12E256CPVE is a 16-bit Microcontroller based on enhanced HCS12 CPU (25MHz bus) with CISC architecture operates at a maximum frequency of 50MHz. The device incorporates 256kB internal flash, 16kB internal RAM, 16-channel 10-bit A/D converter and 90 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, three serial communications interface (SCI) and one serial peripheral interface modules (SPI).
