The MC9S08FL8CLC is an 8-bit HCS08 microcontroller from NXP in LQFP-16, running at 20MHz bus frequency with 8KB Flash and 512B SRAM. The FL sub-family is optimized for low-cost, low-pin-count applications. The HCS08 core executes most instructions in 1-3 bus cycles, with a 16-bit indexed addressing mode and hardware multiply (8×8=16-bit in 3 cycles). The peripherals include: one 16-bit TPM (Timer/PWM Module) with 2 channels supporting input capture, output compare, and edge-aligned PWM; one SCI (Serial Communication Interface) for UART; one I2C module supporting master/slave at up to 400kHz; a 12-channel 10-bit ADC at 250ksps; an analog comparator with selectable reference; and an RTC (Real-Time Counter) with 1ms/4ms timebase from the 32kHz internal reference. The device includes a 1kHz ICS (Internal Clock Source) for startup, a 32kHz internal reference for the RTC, and an external oscillator circuit for crystals up to 32MHz. The BDM (Background Debug Module) provides single-wire in-circuit debugging and Flash programming. The -CLC suffix specifies 8KB Flash, LQFP-16, commercial temperature (0C to +70C). Applications include appliance controls, simple motor control, sensor interfaces, and cost-sensitive consumer electronics.
