C8051F236-GQ

Overview

The C8051F236-GQ is a mixed-signal system-on-chip microcontroller from the Silicon Labs C8051F2xx family. It integrates an 8-bit 8051-compatible core operating at up to 25 MHz with 8 kB of in-system programmable Flash memory and 1.25 kB of RAM. The device features 32 general-purpose I/O pins, hardware UART and SPI interfaces, and supports JTAG debugging. It operates within a voltage range of 2.7 V to 3.6 V and functions across temperatures from -40 °C to +85 °C.

Feature Summary

• Integrates an 8-bit 8051-compatible microcontroller core with in-system programmable Flash for code execution and non-volatile data storage.
• Includes hardware serial communication peripherals such as UART and SPI, eliminating the need for software bit-banging.
• Supports non-invasive, full-speed online debugging via JTAG without requiring external emulation hardware.

Applications

• Industrial control systems
• Sensor interface circuits
• General-purpose embedded applications

Procurement Notes

Verify component status carefully as public records indicate this specific part number may be discontinued or not recommended for new designs. Confirm current availability and lifecycle status directly with authorized distributors or Silicon Labs before finalizing procurement plans to avoid obsolescence risks.

Selection Notes

Select this component when a fully integrated mixed-signal MCU with 8051 compatibility is required. It is suitable for designs needing moderate Flash capacity and basic serial interfaces. Consider newer series if RoHS compliance or long-term supply assurance is critical for the project timeline.

Part Context

This device belongs to the C8051F2xx family of highly integrated mixed-signal system-on-chip MCUs. The family provides various models with differing amounts of Flash, RAM, and analog peripherals, all sharing a common 8051 core architecture and debugging interface capabilities.

Replacement Considerations

Public documentation indicates that similar legacy parts in this family are often replaced by EFM8BB series devices. Verify specific pin-to-pin compatibility and peripheral mapping before substituting with newer generation silicon.
