PRODUCT OVERVIEW

SN8P2614 is a 28 pin general purpose MCU with internal high RC 16MHz and 200mA sink current @VSS+1.5V of Port 2. The combination of Port 1 and Port 2 is for LED panel scan with large current design. Internal high RC 16MHz provides more I/O pin and low cost high clock oscillator selection. SN8P2614 has unique pin assignment not compatible with SN8P2604 or SN8P2604A. The system is base on 4T design for high noisy application, e.g. household products...
