Mingjiada Electronics In Stock Silicon Labs C8051F920-G-GM Ultra-Low Power 8-Bit MCU

Mingjiada Electronics is currently promoting the Silicon Labs 8-bit ultra-low-power microcontroller C8051F920-G-GM — 25 MHz 8051 core | 32 KB Flash | 4.25 KB RAM | 10-bit ADC | Operates from 0.9 V

1. Product Description  

The C8051F920-G-GM is an enhanced 8051 MCU developed by Silicon Labs (Xinke Technology) for battery-powered and energy harvesting applications. The chip features a hardware-reconstructed power management unit, enabling full-speed operation under a single power supply ranging from 0.9 V to 3.6 V; It integrates an efficient DC-DC boost converter that requires only one inductor to boost from 0.9 V to the core's required voltage, truly achieving ‘one battery to go the distance.’

2. Key Parameters  

• Core: Single-cycle 8051, up to 25 MHz  

• Memory: 32 KB Flash + 4.25 KB RAM, supports IAP/ISP

• ADC: 10-bit, 23 channels, 200 ksps, with internal temperature sensor

• Timers: 5 × 16-bit general-purpose timers, enhanced PCA (PWM, capture, frequency output)

• Communication interfaces: UART ×1, SPI ×1, SMBus/I²C ×1

• Low power consumption:

‑ Sleep mode: 50 nA (RAM retained)

‑ Shutdown mode: 0.4 µA (LFO wake-up)

‑ Operating mode: 150 µA/MHz (at 1 MHz)

• Package: 32-VFQFN (4 mm × 4 mm, exposed pad)

• Temperature: -40 °C to +85 °C (industrial grade)

3. Core Features

0.9 V single-cell battery startup: Supports direct power supply from alkaline, button batteries, or energy harvesters.

Integrated high-efficiency boost DC-DC: Requires only one 2.2 µH inductor on the periphery, with efficiency >85%, reducing BOM.

Dual clock system: Enables fast wake-up from 2 µs, suitable for sensor nodes with extremely low duty cycles.  

Rich peripherals: On-chip comparator, VDD monitoring, programmable current source, hardware CRC, simplifying peripheral circuits.  

Development-friendly: Silicon Labs official C8051Fxx development board, Simplicity Studio software, and J-Link debugger are plug-and-play.

4. Typical applications  

• Wireless sensor nodes, environmental monitoring terminals  

• Smart wearables (wristbands, temperature patches, fitness trackers)  

• Energy harvesting systems (solar, thermoelectric, vibration)  

• Industrial instruments, water/electricity/gas meters, smoke detectors

• Medical disposable patches, capsule endoscopes, blood glucose meters
