MC9S12DG256MPVE

其他系列 25MHz 256K@x8bit 12KB

The 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 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.
