C8051F230-GQ

Overview

The C8051F230-GQ is an 8-bit microcontroller from the Silicon Labs C8051F2xx family, featuring a standard 8051 core and operating at a peak frequency of 25 MIPS. It integrates 8 kB of in-system programmable Flash memory and 256 bytes of RAM. The device includes three 16-bit timers, two voltage comparators, and supports up to 32 digital port I/Os. Communication interfaces include SPI and UART modules. It operates within a supply voltage range of 2.7 V to 3.6 V and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates 8 kB of ISP Flash memory for flexible code storage and updates.
• Includes on-chip SPI and UART serial communication interfaces.
• Features multiple general-purpose I/O pins with configurable digital peripheral assignments.

Applications

• Embedded control systems requiring moderate processing power
• Industrial monitoring applications using integrated sensors
• General-purpose data acquisition tasks

Procurement Notes

Verify the specific package variant against project requirements, as the C8051F2xx series utilizes different footprints such as 48TQFP or 32LQFP depending on the exact suffix. Confirm that the absence of an ADC aligns with system design needs, as other variants in this family provide analog conversion capabilities. Ensure compatibility with existing development tools for the 8051 architecture.

Selection Notes

Select this component when a cost-effective 8-bit solution with sufficient I/O count is required without analog input needs. Compare against C8051F22x variants if additional RAM or ADC channels are necessary. Consider the 25 MHz performance limit for timing-critical applications and verify that the 8 kB Flash capacity meets firmware size projections.

Part Context

This part belongs to the C8051F2xx series of mixed-signal System-on-Chip microcontrollers. These devices are designed to reduce component count by integrating peripherals typically found on separate chips. The series emphasizes high integration and low power consumption while maintaining full compatibility with standard 8051 instruction sets.

Replacement Considerations

Direct substitutes within the same family include C8051F206-GQ, C8051F220-GQ, C8051F221-GQ, C8051F226-GQ, C8051F231-GQ, and C8051F236-GQ. Selection depends on matching pin counts, package types (TQFP vs LQFP), and specific peripheral availability such as ADC presence.
