C8051F986-GMR

Overview

The C8051F986-GMR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a CIP-51 core operating at up to 25MHz. It integrates 8KB of flash memory and 512 bytes of RAM within a 24-pin QSOP package. The device supports 1.8V to 3.6V supply voltages and includes peripherals such as SMBus, SPI, UART/USART, PWM, and a temperature sensor. It operates within a -40°C to +85°C temperature range.

Feature Summary

Integrates a CIP-51 8051-compatible core with internal oscillator for efficient code execution.
Includes on-chip analog-to-digital conversion capabilities with 10 channels and 12-bit resolution.
Supports multiple serial communication interfaces including SMBus, SPI, and UART/USART.
Features integrated system monitoring functions such as power-on reset and watchdog timer.

Applications

Battery-powered embedded systems requiring low voltage operation
Industrial control applications utilizing serial communication protocols
Temperature monitoring devices leveraging internal sensors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 24-QSOP specification. Check for RoHS compliance status and ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when an 8-bit architecture with moderate flash capacity and integrated ADC is required. Consider the 24-pin QSOP package for surface-mount assembly constraints. Evaluate peripheral needs against available SMBus, SPI, and UART resources before finalizing the design choice.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers designed for cost-sensitive applications. It shares architectural similarities with other members like the C8051F985 but offers distinct I/O counts and packaging options suitable for compact designs.
