C8051F988-C-GM

Overview

The C8051F988-C-GM is an 8-bit microcontroller from the Silicon Labs C8051F9xx series, utilizing the CIP-51 core. It features 4KB of in-system programmable Flash memory and 512 bytes of RAM. The device operates at a maximum clock frequency of 25MHz with a supply voltage range of 1.8V to 3.6V. It integrates ten 10-bit ADC channels and supports interfaces including Enhanced SPI, UART, I2C, and SMBus. Packaged in a 24-WFQFN (4x4) exposed pad, it functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates ten 10-bit analog-to-digital converter channels for signal acquisition.
• Includes on-chip peripherals such as PWM, watchdog timer, and power-on reset.
• Supports multiple serial communication protocols via enhanced SPI, UART, and I2C/SMBus interfaces.

Applications

• Battery-powered sensor nodes requiring low-voltage operation
• Industrial control systems utilizing analog input monitoring
• Embedded devices needing compact surface-mount packaging

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the 24-WFQFN specification. Review official errata documents for the C8051F99x/98x series prior to implementation. Ensure design compatibility with the specified 1.8V to 3.6V supply range and thermal requirements.

Selection Notes

Select this component for applications requiring integrated analog conversion capabilities within a small form factor. The inclusion of ten 10-bit ADC channels reduces external component count compared to solutions lacking internal converters. Evaluate the 4KB Flash capacity against firmware size requirements. Consider the 25MHz processing speed for real-time control loops.

Part Context

This part belongs to the C8051F9xx family of mixed-signal microcontrollers. These devices combine a CIP-51 processor with high-performance analog peripherals on a single chip. The family targets cost-sensitive embedded applications where space and power efficiency are critical constraints.

Replacement Considerations

Consult official substitution lists for compatible parts within the C8051F9xx series. Verify pinout and register compatibility before replacing existing designs. Cross-reference specific suffix variations for package or temperature grade differences.
