Product Introduction

SH79F328 is a high-speed and high-efficiency 8051 compatible microcontroller. At the same oscillation frequency, it has the superior feature of running faster compared to traditional 8051 chips.

SH79F328 retains most of the features of the standard 8051 chip. These features include built-in 256 byte RAM, 3-channel UART, and external interrupts INT0, INT1, INT2, INT3, and INT4. In addition, SH79F328 also integrates external 1280 byte RAM. The microcontroller also includes a 32K byte Flash block suitable for program storage.

SH79F328 not only integrates standard communication modules such as EUART/TWI/SPI, but also modules such as dimmable LED, LCD driver, 12 bit ADC, PWM timer, etc.

In addition, SH79F328 also has a built-in 24 channel Touchkey module, CRC module, and digital logic configurable (LCM) module.

In order to achieve high reliability and low power consumption, SH79F328 has built-in watchdog timer, low voltage reset function, and system clock monitoring function. In addition, SH79F328 also provides two low-power power-saving modes.
