Package Outline
Description

SC51P6604 bases on SC51 core and embeds 4K-byte OTP and 128-byte RAM. It integrates a 16MHz high accuracy RC oscillator RCH, a 6-channel 8-bit ADC, a universal pulse generator UPG that supports two complementary PWM outputs. It is applicable to the auxiliary monitoring of LED light control, DC motor, small household appliances, electric tools and various electronic systems.


Features：

8 bit SC51 CPU

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

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

  • Stack overflow reset.

On-Chip Memory

  • 4K-byte OTP, data retention time > 10 years.

  • 128-byte RAM.

  • 256-byte E2PROM (only for SC51P66E04SA1G)

  • Support In-System-Programming (ISP), only 5-pins are needed (including VDD/VSS).

  • Support multi-time-programming (MTP): 1Kx4 times/2Kx2 times/4Kx1 time.

  • Support OTP page encryption, page size: 1K.

Power supply and Reset

  • Operating voltage: 2.4V~5.5V.

  • Built-In Power-On-Reset (POR).

  • Built-In Low-Voltage-Reset (LVR) with 4 levels selectable, 2.0V, 2.6V, 3.0V, 3.6V.

  • Built-In Low-Voltage-Detect (LVD) with 8 levels selectable, 2.3V, 2.5V, 2.7V, 3.0V, 3.5V, 3.7V, 3.9V, 4.3V.

  • Built-in watchdog (WDT).

System clock 

  • Built-In 20KHz low frequency Oscillator (RCL).

  • Built-In 16MHz high precision Oscillator (RCH).

  • CPU maximum operating frequency: 8MHz @ 2.7~5.5V.
