C8051F005-GQ

Overview

The C8051F005-GQ 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, providing 25MIPS throughput. The device integrates 32KB of in-system programmable (ISP) Flash memory and 2304 bytes of internal SRAM. Key analog peripherals include an 8-channel 12-bit SAR ADC with a programmable gain amplifier, two 12-bit DACs, and two analog comparators. Digital interfaces consist of hardware SMBus, SPI, and UART ports. The unit operates within a supply voltage range of 2.7V to 3.6V and supports a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a pipelined 8051 CPU core capable of executing instructions in one or two system clocks for high-speed processing.
• Includes on-chip JTAG debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulation hardware.
• Features a complete mixed-signal peripheral set including a 12-bit ADC with programmable gain, dual 12-bit DACs, and precision voltage reference.
• Provides flexible digital I/O via a programmable crossbar that maps multiple peripheral signals to general-purpose pins.

Applications

• Data acquisition systems utilizing the integrated 12-bit ADC and temperature sensor
• Industrial control applications requiring simultaneous serial communication via SMBus, SPI, and UART
• Signal generation and conditioning using dual 12-bit DACs and analog comparators
• Embedded systems requiring in-system programming and real-time debugging capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific GQ package variant matches design requirements. Note that this part is marked as not recommended for new designs; evaluate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this model when a fully integrated mixed-signal solution is required to minimize board space. The inclusion of ISP Flash allows for field updates without external programmers. Ensure the application benefits from the concurrent availability of multiple serial communication protocols and the high-speed data conversion capabilities provided by the onboard peripherals.

Part Context

This component belongs to the C8051F0xx family of mixed-signal MCUs. It shares architectural similarities with variants like the C8051F000 and C8051F006 but is distinguished by its specific memory configuration and peripheral allocation. The GQ suffix denotes the 64-pin TQFP package format suitable for surface-mount assembly.
