The 8-bit HCS08 microcontroller uses an enhanced HCS08 CPU with a 40 MHz core and 20 MHz internal bus. It integrates 96 KB of Flash memory and 6 KB of RAM with read, program, and erase support across the specified operating range. The device family includes a 16-channel 10-bit ADC, two SCI interfaces, two SPI interfaces, an IIC bus module, keyboard interrupt inputs, CRC support, and three 16-bit timer/PWM modules. Operating voltage is specified from 2.7 V to 5.5 V, with C temperature range devices rated for -40 °C to 85 °C and M temperature range devices rated for -40 °C to 125 °C. Package options for this memory size include 80-pin LQFP, 64-pin QFP, and 44-pin LQFP.
