MC9S12A256CPVE

The MC9S12A256CPVE is a 16-bit Microcontroller based on enhanced HCS12 CPU with CISC architecture operates at a maximum frequency of 25MHz. The device incorporates 256kB internal flash, 12kB internal RAM, 4kB EEPROM, 8-channel 10-bit A/D converter and 91 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module, two 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). An inter IC (I2C) bus minimizes the need for large numbers of connections between devices and eliminates the need for an address decoder and also provides a simple, efficient method of data exchange between devices.
