General Description

SH66P51 is dedicated to infrared remote control transmitter with LCD applications. This chip integrates the SH6610C 4-bit

CPU core with SRAM, OTP ROM, one 8-bit timer, one base timer, LCD driver, programmable input/output driving buffers,

carrier synthesizer, and voltage regulator. This chip integrates a dual-oscillator to enhance the total chip performance.
