C8051F902-D-GM

Overview

The C8051F902-D-GM is an 8-bit microcontroller from Silicon Labs featuring a high-speed CIP-51 core operating at up to 25 MIPS. It integrates 8 kB of in-system programmable Flash memory and 768 bytes of RAM. The device includes a 12-bit SAR ADC with a throughput of 75 ksps, two voltage comparators, and a built-in DC-DC converter supporting operation from 0.9 V to 3.6 V. It offers 16 port I/O pins, hardware SMBus, dual SPI, and UART interfaces within a compact 24-pin QFN package.

Feature Summary

• Integrated DC-DC converter enables low-voltage single-cell battery operation
• High-resolution 12-bit analog-to-digital converter with auto-averaging accumulator
• Pipelined instruction architecture for efficient code execution
• On-chip debug circuitry supports non-intrusive in-system debugging

Applications

• Single-cell battery-powered embedded systems
• Portable consumer electronics requiring ultra-low power consumption
• Industrial monitoring applications utilizing on-chip temperature sensors
• Battery management systems leveraging the built-in supply monitors

Procurement Notes

Verify the specific suffix 'D' indicates tape and reel packaging when sourcing components. Confirm the manufacturer part number matches the exact silicon revision required for your design. Check current availability status as this component may be subject to obsolescence notices. Ensure the operating temperature range meets your environmental specifications before finalizing procurement.

Selection Notes

Select this model when a balance of moderate Flash capacity and high-resolution analog conversion is required. The integrated DC-DC converter makes it suitable for designs powered by a single lithium cell. Consider the 24-pin QFN footprint constraints during PCB layout. Evaluate the 16 available I/O lines against peripheral requirements to ensure sufficient connectivity without external multiplexing.

Part Context

This component belongs to the C8051F9xx series of mixed-signal microcontrollers. It shares architectural similarities with the C8051F91x devices but features reduced Flash memory capacity. The series is characterized by its focus on ultra-low power modes and comprehensive analog peripherals within a small form factor.
