Description

SC51P03A04 is 3V I/O type 8-bit MCU with low power consumption. 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 timer function and carrier generator equivalent to 8-bit PWM make the SC51P03A04 suitable for various small home appliances control.


Features：

  • Compatible with MCS51 instruction set; dual DPTR; add software reset instruction.

  • Improved instruction structure, the execution time of 90% instructions is two to four clock cycles.

  • 4K-byte OTP, 4×1K MTP, data retention>10 years.

  • 128-byte RAM.

  • Support In-System Programming (ISP) with only five pins.

  • Built-in power on reset(POR) and low voltage reset (LVR).

  • Support up-to 18 I/O ports .

  • Ports of P1 and P2 have keyboard interrupt awake function (KI0~KI7) with settable interrupt polarity. 

  • Two external interrupt inputs(INT0/INT1) with settable interrupt polarity. 

  • Built-in watchdog timer (WDT). 

  • Two 16-bit standard timers(T0/T1).

  • Built-in carrier generator (CRG) for carrier modulation.

  • Built-in high current open-drain output transistor, settable drive ability, IOL=180/250mA@VOL=0.3V, VDD=3V. 

  • Built-in high accuracy oscillator (RCH): 4MHz ±1% @TA= -10~50°C, VDD=1.8~3.6V.

  • Built-in 20KHz low frequency oscillator (RCL).

  • External 1~8MHz high frequency oscillator.

  • Prescale setting for system clock with factors: 1/2/8/64.

  • Idle mode and Stop mode.

  • Operating voltage: 1.8V~3.6V; typical operating current: 1mA@4MHz; stop current is less than 1μA. 

  • 16-pin SOP package, 20-pin TSSOP package.
