Product Summary
The MC68HC908RF2CFA MCU is a low-cost, high-performance 8-bit microcontroller unit (MCU). Optimized for low-power operation and available in a small 32-pin low-profile quad flat pack (LQFP), this MCU is well suited for remote keyless entry (RKE) transmitter designs. The MC68HC908RF2CFA is based on the customer-specified integrated circuit (CSIC) design strategy.
