C8051F713-GQR

Overview

The C8051F713-GQR is an 8-bit mixed-signal ISP Flash MCU from the C8051F70x/71x family by Silicon Labs. It features a high-speed pipelined 8051 core operating at up to 25 MHz, delivering 25 MIPS throughput. The device integrates 16 kB of in-system programmable Flash memory, 512 bytes of internal data RAM, and 32 bytes of data EEPROM. Key analog peripherals include a 10-bit ADC with up to 500 ksps conversion rate, a capacitance-to-digital converter supporting up to 38 channels, and an analog comparator. Digital interfaces encompass UART, SMBus, SPI, and four general-purpose timers. It operates on a supply voltage range of 1.8 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrates a capacitance-to-digital converter for sensing buttons, sliders, wheels, proximity, and touch screens with auto-scan capabilities.
• Features a high-speed 8051 microcontroller core with a pipelined architecture executing most instructions in one or two system clocks.
• Includes a 10-bit analog-to-digital converter capable of up to 500 ksps sampling rates with multiple reference options.
• Provides non-intrusive on-chip debug circuitry facilitating full-speed in-system debugging without external emulators.

Applications

• Capacitive touch sensing interfaces
• Industrial control systems
• Portable battery-powered instruments

Procurement Notes

Verify component status as this series is marked Not Recommended for New Designs. Confirm package type matches the GQR suffix (TQFP-48). Check for specific revision updates in official datasheets before finalizing designs due to potential lifecycle changes.

Selection Notes

Select this component when existing designs require migration within the C8051F70x/71x family. Ensure application requirements align with the 1.8 V to 3.6 V supply range. Verify that the 16 kB Flash capacity meets program storage needs and that the integrated capacitive sense module satisfies input channel requirements.

Part Context

This part belongs to the C8051F70x/71x mixed-signal MCU family, which emphasizes high integration and low cost. The family shares common architectural features such as the CIP-51 core and flexible interrupt handling. The GQR suffix specifically denotes the TQFP-48 surface-mount package variant suitable for compact PCB layouts.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other members of the C8051F7xx family if pin compatibility allows, though specific cross-references require manufacturer validation.
