C8051F713-GQ

Overview

The C8051F713-GQ is a mixed-signal ISP Flash MCU from the Silicon Labs C8051F70x/71x family, featuring a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. It includes 16 kB of in-system programmable Flash memory, 512 bytes of internal data RAM, and up to 32 bytes of data EEPROM. The device integrates a capacitance-to-digital converter supporting up to 38 input channels for touch sensing, a 10-bit ADC with up to 500 ksps sampling rate, and an analog comparator. Digital peripherals include hardware UART, SMBus, SPI, four 16-bit timers, and a PCA with PWM functionality. It operates on a supply voltage of 1.8 V to 3.6 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrated capacitance-to-digital converter supports buttons, sliders, wheels, capacitive proximity, and touch screen sensing with auto-scan capabilities.
• On-chip debug circuitry facilitates full speed, non-intrusive in-system debug without requiring external emulation hardware.
• High-speed pipelined 8051 microcontroller core executes 70% of instructions in one or two system clocks.
• Hardware-enhanced serial interfaces including UART, SMBus, and SPI enable efficient communication protocols.

Applications

• Capacitive touch sensing applications such as buttons, sliders, and proximity detection
• Industrial control systems requiring mixed-signal processing and robust I/O
• Battery-powered devices utilizing low-voltage operation and power management modes

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package type matches the TQFP-48 specification. Check datasheet revisions for updates regarding electrical characteristics. Ensure environmental compliance documentation aligns with project requirements. Validate pinout compatibility during PCB layout finalization.

Selection Notes

Select this MCU for designs requiring integrated capacitive sensing alongside standard analog conversion. Evaluate memory constraints against the 16 kB Flash and 512 B RAM limits. Consider the 1.8 V to 3.6 V operating range for power supply design. Assess peripheral needs for UART, SPI, and timer counts before finalizing the part number.
