C8051F007-GQ

Overview

The C8051F007-GQ is a mixed-signal microcontroller from the Silicon Labs C8051F0xx family, featuring a high-speed 8051-compatible CPU core capable of up to 25 MIPS throughput at a 25 MHz clock frequency. It integrates 32 KB of in-system programmable (ISP) Flash memory and 2304 bytes of internal SRAM. The device includes a 12-bit SAR ADC with up to eight external inputs, two 12-bit DACs, two analog comparators, and a precision voltage reference. Digital peripherals include hardware SMBus, SPI, and UART interfaces, alongside a Programmable Counter Array and four general-purpose timers.

Feature Summary

• Integrates a pipelined 8051 CPU core executing instructions in one or two system clocks for high throughput.
• Features on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Includes a 12-bit successive approximation ADC with programmable gain amplifier and data-dependent windowed interrupt generator.
• Provides simultaneous hardware support for SMBus, SPI, and UART serial communication protocols.

Applications

• In-system programming applications requiring direct code updates via ISP.
• Mixed-signal control systems utilizing integrated analog-to-digital conversion and digital-to-analog output.
• Embedded designs needing concurrent serial communication through multiple hardware ports.
• Battery-powered devices leveraging low-power sleep and shutdown modes.

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the ordered suffix, as variations exist within the family. Ensure compliance with RoHS standards if required by your assembly process. Note that this specific model is marked as not recommended for new designs; evaluate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a complete mixed-signal solution is needed without external ADCs or DACs. The 2304-byte RAM distinguishes it from smaller variants like the F000/F001 which have only 256 bytes. Consider the 12-bit ADC resolution requirement versus the 10-bit option available in other family members. Verify that the 2.7V to 3.6V supply range aligns with your system power architecture.

Part Context

This part belongs to the Silicon Labs C8051F0xx mixed-signal MCU family, which shares a common architectural foundation including the CIP-51 CPU and crossbar interface. While sharing core features with siblings like the C8051F005 and C8051F006, the F007 variant specifically offers the larger 2304-byte SRAM configuration. The family emphasizes single-chip integration to reduce bill-of-materials count in embedded applications.
