III. SH79F6488P/064PR Key Product Features

1. Powerful Analog Front End

Integrated 20-bit high-precision Σ-Δ ADC, combined with a programmable gain amplifier (1X–128X gain range), meets the requirements for weak signal acquisition and is suitable for precision measurement scenarios such as sensor data acquisition, electronic scales, and medical testing.

2. Extensive Human-Machine Interaction Capabilities

The chip integrates a high-capacity LCD driver supporting up to 6×34-segment displays. It can drive segmented LCD screens without requiring an external driver chip, simplifying PCB design and reducing BOM costs. This makes it particularly suitable for home appliances and instrumentation products with display functions.

3. Comprehensive Peripheral Communication Interfaces

It provides enhanced UART and SPI interfaces, enabling easy connection to external devices such as Bluetooth modules, Wi-Fi modules, sensors, and memory chips, meeting the networking and communication requirements of IoT end devices.

4. Low-Power Design

It offers two low-power operating modes: idle mode and power-down mode. Combined with an ultra-low-power LCD operating mode, these significantly extend the battery life of battery-powered devices.

5. Reliable System Protection

Integrated Low Voltage Reset (LVR) and Watchdog Timer (WDT) ensure stable system operation in complex electromagnetic environments.

6. Convenient Development and Debugging

The Zhongying SH79F series microcontrollers support online simulation and programming via the JET51 emulator. This tool is based on the Keil µVision integrated development environment and connects to the target board via JTAG.
