C8051F983-C-GMR

Overview

The C8051F983-C-GMR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, utilizing a standard 8051 core architecture. It features 4 kB of in-system programmable Flash memory and 512 bytes of data RAM. The device operates at a maximum clock frequency of 25 MHz with a supply voltage range of 2.2 V to 3.6 V. It is housed in a QFN-20 package and lacks an integrated analog-to-digital converter.

Feature Summary

• Integrates 8051-compatible processing core with in-system Flash programming capabilities
• Supports low-voltage operation within a 2.2 V to 3.6 V power supply range
• Includes digital communication interfaces such as SPI, I2C, and UART for system connectivity

Applications

• Battery-powered embedded systems requiring low power consumption
• Industrial control applications utilizing digital communication protocols
• General-purpose microcontroller tasks in space-constrained designs

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lifecycle notices regarding obsolescence. Ensure the QFN-20 package variant matches design requirements before procurement.

Selection Notes

Select this component when an 8-bit 8051 architecture is required without analog sensing needs. Consider the absence of an ADC and limited RAM size against application complexity. Evaluate the 25 MHz speed and QFN-20 footprint for suitability in compact, cost-sensitive designs.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers by Silicon Labs. While many siblings include ADCs and DC-DC converters, the C8051F983 specifically omits these peripherals to reduce complexity and cost, focusing on digital processing and communication.
