C8051F988-C-GUR

Overview

The C8051F988-C-GUR is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, featuring a CIP-51 8051 core. It integrates 8KB of Flash memory and 512 bytes of RAM. The device operates at a maximum frequency of 25MHz with a supply voltage range of 1.8V to 3.6V. It includes a 10x12-bit ADC, CapSense interface, and multiple digital communication peripherals. The component is housed in a 24-pin QSOP package.

Feature Summary

Integrates a high-performance CIP-51 8051 core for efficient instruction execution.
Includes a 10-channel, 12-bit analog-to-digital converter for precision signal acquisition.
Features a dedicated CapSense interface for capacitive touch sensing applications.
Supports standard digital communication protocols including SPI, I2C, and UART.

Applications

Capacitive touch sensor interfaces
Portable battery-powered instrumentation
Industrial control systems requiring mixed-signal processing

Procurement Notes

Verify current availability status as this part number may be subject to end-of-life restrictions or limited distribution channels. Confirm package type and suffix specifications against official datasheets prior to integration. Ensure compliance with RoHS directives and moisture sensitivity levels during storage and handling procedures.

Selection Notes

Select this component for designs requiring integrated capacitive sensing capabilities alongside standard 8-bit MCU functions. Consider the 24-pin QSOP package constraints for PCB layout. Evaluate power consumption requirements against the 1.8V to 3.6V operating range to ensure compatibility with system voltage rails.

Part Context

This microcontroller belongs to the C8051F9xx family, which emphasizes mixed-signal integration on a single chip. The series combines digital processing with analog peripherals, reducing external component count. The C8051F988 variant specifically targets applications needing touch sensing and moderate data conversion resolution within a compact footprint.

Replacement Considerations

Consult official substitution lists for compatible parts within the C8051F9xx series. Verify pinout compatibility and peripheral configuration differences before replacing existing inventory.
