The MC9S08AC8CFDE is an 8-bit microcontroller from Quarktwin Technology Ltd. featuring a 40 MHz HCS08 central processor unit (CPU) with a 20 MHz internal bus frequency. It supports the HC08 instruction set and includes a background debugging system with breakpoint capabilities. The microcontroller offers up to 8 KB of on-chip FLASH memory and 1 KB of RAM, with various clock source options including crystal and internal clock generation. This device is equipped with multiple peripherals, including an 8-channel, 10-bit analog-to-digital converter (ADC), two serial communication interfaces (SCI), a serial peripheral interface (SPI), and an inter-integrated circuit (IIC) bus module. It also features three 16-bit timer/pulse-width modulator (TPM) modules and a keyboard interrupt module. The MC9S08AC8CFDE provides up to 38 general-purpose input/output (I/O) pins, with software-selectable pull-ups and drive strength. It includes system protection features such as low-voltage detection and illegal opcode detection. The microcontroller is available in various package options, including a 48-pin quad flat no-lead package (QFN) and a 44-pin low-profile quad flat package (LQFP). This product is suitable for consumer and industrial applications.
