SC51P2317 is a 3V I/O type 8-bit low power MCU. It bases on powerful SC51 CPU core and embeds 16K-byte OTP, 512-byte RAM and 1K-byte E2PROM. It integrates comparator, voltage detector, carrier modulation and demodulation module and three configurable timers, which is very suitable for self-learning remote control. It supports three kinds of low power operating modes and peripheral clock gating, which is very suitable for battery-powered systems.
