Product Introduction

The SC92F73AX integrates 8 Kbytes Flash ROM, 1 KBytes SRAM, 128 bytes EEPROM, up to 26 GP I/Os, 13 IOs with external interrupts, 3 16 bit timers, 11 12 bit high-precision ADCs, 6 independent 10 bit PWM, an internal 1 PERCENT high-precision high-frequency 16/8/4/1.33MHz oscillator and 4 PERCENT precision low-frequency 128K oscillator, an external crystal oscillator, a UART, and a UART/SPI/IC three choice one communication port SSI. To improve reliability and simplify customer circuits, the SC92F73AX also integrates high reliability circuits such as 4-level optional voltage LVR and 2.4V reference ADC voltage internally. The SC92F73AX has excellent anti-interference performance and is very suitable for use in various applications such as smart home appliances and smart homes, the Internet of Things, wireless communication, game consoles, and industrial control and consumer applications.

System clock (fSYS):

?  Built in high-frequency 16MHz oscillator (fHRC)

?  When used as a system clock source, fSYS can be set to 16/8/4/1.33MHz through a programmer selection

?  Frequency error: Across (2.9V~5.5V) and (-10~85 ℃) application environments, not exceeding ± 1 PERCENT

?  Built in high-frequency crystal oscillator circuit

?  Can be connected to an external 2~16MHz oscillator

?  When used as a system clock source, fSYS can be programmed to choose one of the four frequency divisions: external crystal oscillator/1/2/4/12

?  The operating voltage range corresponding to the IC system clock (fSYS)

? > 12MHz @2.9~5.5V

? ≤ 12MHz @2.4~5.5V
