Product description

SC51P0304 is 3V I/O type 8-bit MCU with low power dissipation. It uses SC51 core with built-in 4K-byte OTP and 128-byte RAM. It features 1.8V~3.6V operating voltage range, super-low Stop current, and low operating current under low frequency, which makes it well suitable for the battery-powered systems. The 4K-byte OTP, optimized anti-interference ability, 8mA pin driving ability, rich itmer function and carrier generator equivalent to 8-bit PWM make the SC51P0304 suitable for various small home appliances control.

	Features
	Compliance with MCS51 structions; dual DPTR; add software reset instructions. Improved instruction structure, the execution time of 90% instructions is two to four clock cycles. 4K-byte OTP, 4×1K MTP, data holding>10years. 128-byte RAM. Support In-System Programming (ISP) with only five pins. Built-in power on clear (POC) and low voltage reset (LVR). 17 I/O ports and one open-drain output. 8 pins have keyboard interrupt awake function with settable interrupt polarity. Two external interrupt inputs with settable interrupt polarity. Built-in dynamic keyboard wakeup (DKW) module supporting trapezoidal keyboard connection. Built-in watchdog timer (WDT). Two 16-bit standard timers. Built-in carrier generator (CRG) for carrier modulation. Built-in high current open-drain output transistor, IOL=180mA@VOL=0.3V, VDD=3V. Built-in 4MHz high accuracy oscillator (RCH), with error of not more than ±2% under 0~50°C/1.8~3.6V condition. Built-in 20KHz low frequency oscillator (RCL). External 1~8MHz high frequency oscillator. Prescale setting for system clock with factors: 1/2/8/64. Sleep mode and Stop mode. Operating voltage: 1.8V~3.6V; typical operating current: 1mA@4MHz; shutdown current is less than 1μA; typical current of dynamic keyboard scan is 1.5μA. 8/16-pin SOP package, 20-pin SOP/SSOP package.

	Applications
	Remote control Motor control Small home appliances control Power management
