The MC9S08AW60/48/32/16 is an MCU based on the 8-bit HCS08 CPU, with a 40MHz CPU frequency, a 20MHz internal bus frequency, a HC08 instruction set, a single-wire background debug mode interface, breakpoint capability, and support for up to 32 interrupt/reset sources.
The document is an advance information data sheet for the MC9S08AW60, MC9S08AW48, MC9S08AW32 and MC9S08AW16 microcontrollers based on the HCS08 architecture. It covers core features such as a 40 MHz CPU, 20 MHz internal bus, up to 60 KB flash, 2 KB RAM, a 16‑channel 10‑bit ADC and a range of serial interfaces.
The sheet includes detailed sections on pins and connections, modes of operation, memory map, reset and interrupt handling, peripheral modules (GPIO, timers, SCI, SPI, I²C), clock generation, and extensive electrical characteristics. Ordering information and mechanical drawings for the various package options are also provided.
