NXP MC9S08AC128 Series 8-Bit Microcontrollers Reference Manual
Reference manual for NXP MC9S08AC128 and MC9S08AC96 8-bit HCS08 microcontrollers, covering architecture, memory, peripherals, and system configuration.
Overview
This reference manual provides technical specifications and functional descriptions for the NXP MC9S08AC128 and MC9S08AC96 microcontrollers. Based on the 8-bit HCS08 CPU architecture, these devices feature a 40-MHz CPU, 20-MHz internal bus frequency, and a Memory Management Unit (MMU) for paged memory support. The document details memory options up to 128KB Flash and 8KB RAM, alongside internal clock generation and system protection features like CRC modules and low-voltage detection. Integrated peripherals include a 16-channel 10-bit ADC, multiple serial interfaces (SCI, SPI, IIC), and flexible 16-bit timer/PWM modules. The manual also covers development support through background debugging and on-chip in-circuit emulation.
Use Cases
