C8051F005-GQR

Overview

The C8051F005-GQR is a mixed-signal System-on-Chip microcontroller from the Silicon Labs C8051F0xx family. It features a high-speed 8051 CPU core operating at up to 25MHz (25MIPS). The device integrates 32KB of in-system programmable Flash memory and 2304 bytes of internal SRAM. Key analog peripherals include an 8-channel, 12-bit SAR ADC with a programmable gain amplifier and two 12-bit DACs. Digital interfaces consist of hardware SMBus, SPI, and UART modules. The component operates within a supply voltage range of 2.7V to 3.6V and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Includes on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulation hardware.
• Features a 12-bit successive approximation ADC with a programmable gain amplifier and data-dependent windowed interrupt generator.
• Provides concurrent digital communication capabilities via hardware SMBus, SPI, and UART serial ports.

Applications

• Data acquisition systems requiring precise analog signal processing
• Industrial control applications utilizing onboard sensors and comparators
• Embedded measurement instruments and test equipment
• Battery-powered devices leveraging multiple power-saving sleep modes

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the datasheet covers multiple form factors including TQFP-64, TQFP-48, and LQFP-32. Confirm the revision level of the silicon against the latest product change notices. Note that this component is marked as not recommended for new designs; ensure long-term availability requirements are met before finalizing procurement plans.

Selection Notes

Select this part when a complete mixed-signal solution is needed to minimize external components. The integrated 12-bit ADC and dual DACs reduce board space compared to discrete solutions. Ensure the application fits within the 2.7V to 3.6V supply voltage constraints. Consider the 2304-byte RAM size for complex algorithm implementation versus smaller variants in the F00x family.

Part Context

This component belongs to the C8051F0xx mixed-signal MCU family, which shares a common architecture but varies in memory size and peripheral counts. The C8051F005 specifically offers a balanced mix of 32KB Flash and extensive analog peripherals. It is distinct from the C8051F1xx series, which typically includes USB interfaces and higher clock speeds.
