C8051F315-GM

Overview

The C8051F315-GM is an 8-bit microcontroller from the C8051F31x family, featuring a high-speed CIP-51 core operating at up to 25 MHz. It integrates 8 kB of in-system programmable Flash memory and 1280 bytes of internal data RAM. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports industrial temperatures from -40 °C to +85 °C. It is housed in a 28-pin QFN package and includes hardware-enhanced UART, SMBus, and SPI interfaces.

Feature Summary

• Features a pipelined CIP-51 architecture that executes most instructions in one or two system clocks for high throughput.
• Includes on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Provides a programmable digital crossbar allowing flexible configuration of peripheral pins and I/O ports.
• Integrates multiple digital peripherals including timers, a programmable counter array, and serial communication ports.

Applications

• Industrial control systems
• Consumer electronics devices
• Sensor interface circuits
• Communication gateway nodes

Procurement Notes

Verify the specific suffix GM indicates the 28-pin QFN package variant. Confirm RoHS compliance status through official documentation. Check for the Not Recommended for New Designs notice when planning long-term production. Ensure development tools support the C2 interface for programming and debugging this specific silicon revision.

Selection Notes

Select this component if a highly integrated mixed-signal MCU with direct 8051 compatibility is required. Consider the 25 MIPS performance and low power stop mode for battery-operated applications. Evaluate the available GPIO count against system pin requirements. Verify that the 8 kB Flash size meets application code storage needs.

Part Context

This part belongs to the C8051F31x series of ISP Flash MCUs by Silicon Labs. The family shares a common core and peripheral set but varies in memory size and ADC channel counts. The C8051F315 specifically offers 8 kB Flash and lacks the 12-bit ADC found in other variants like the F310 or F316.

Replacement Considerations

Direct substitutes include other members of the C8051F31x family such as the C8051F310, C8051F311, C8051F312, C8051F313, C8051F314, C8051F316, and C8051F317. These parts share the same core and package options but differ in Flash capacity and analog peripheral availability.
