C8051F230-GQR

Overview

The C8051F230-GQR is an 8-bit microcontroller from the Silicon Labs C8051F2xx family, featuring a fully static 8051-compatible core. It integrates 8 kB of in-system programmable Flash memory and 256 bytes of RAM. The device operates at clock speeds up to 25 MIPS with an internal oscillator. Key peripherals include three 16-bit timers, UART, SPI interfaces, and two voltage comparators. It provides 32 digital port I/O pins and supports supply voltages from 2.7V to 3.6V within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates 8 kB of in-system programmable Flash memory for code storage.
• Includes a fully static 8051-compatible microcontroller core.
• Features on-chip analog components such as voltage comparators.
• Supports serial communication via integrated UART and SPI modules.

Applications

• Embedded systems requiring in-system programming capabilities
• Applications utilizing voltage comparison logic
• Serial communication interfaces using UART or SPI protocols

Procurement Notes

Verify the specific package variant, as the GQR suffix denotes a Tape and Reel configuration. Confirm that the target application voltage remains within the 2.7V to 3.6V operational range. Ensure compatibility with the 8051 instruction set architecture before integration into the design.

Selection Notes

Select this component when a fully static 8051 core is required alongside in-system programmability. It is suitable for designs needing limited Flash capacity but requiring multiple digital I/O lines. Consider the absence of an onboard ADC if analog signal acquisition is necessary for the project.

Part Context

This part belongs to the C8051F2xx series of mixed-signal system-on-chip microcontrollers. The series is characterized by high integration levels, combining standard 8051 functionality with various analog and digital peripherals on a single die, targeting cost-sensitive embedded applications.

Replacement Considerations

Other members of the C8051F2xx family may serve as alternatives if different pin counts or peripheral configurations are needed. Verify Flash size and I/O availability against the original requirements when selecting a substitute.
