MC9S12E128CFUE

The MC9S12E128CFUE 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 128kB internal flash, 8kB internal RAM, 16-channel 10-bit A/D converter and 58 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). The MC9S12E128 has full 16-bit data paths throughout. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements.
