C8051F714-GQ

Overview

The C8051F714-GQ is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F70x/71x family, housed in a 64-pin TQFP package. It features a high-speed pipelined 8051 core operating at up to 25 MHz with 25 MIPS throughput. The device includes 16 kB of ISP Flash memory, 512 bytes of internal data RAM, and 32 bytes of data EEPROM. Integrated peripherals include a 10-bit ADC supporting up to 500 ksps, a capacitance-to-digital converter, analog comparators, four 16-bit timers, a programmable counter array, and multiple serial interfaces.

Feature Summary

• Capacitance-to-Digital Converter supports sensing applications such as buttons, sliders, wheels, proximity detection, and touch screens with auto-scan capabilities.

Applications

• Capacitive sensing for buttons, sliders, wheels, and touch screens
• Mixed-signal control systems requiring on-chip A/D conversion
• Industrial monitoring using built-in temperature sensors

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm component status as the datasheet indicates this family is not recommended for new designs. Ensure compatibility with existing development tools and verify pin assignments for the 64-pin TQFP configuration before procurement.

Selection Notes

Select this component when a complete mixed-signal solution is required within a single chip. The integrated capacitance-to-digital converter eliminates external components for touch interfaces. The high-speed 8051 core provides sufficient processing power for real-time control loops while maintaining low power consumption through various sleep modes.

Part Context

This part belongs to the C8051F70x/71x series of mixed-signal ISPs Flash MCUs. These devices are designed to integrate extensive analog and digital peripherals onto a standard 8051 architecture. The GQ suffix denotes the 64-pin Thin Quad Flat Package (TQFP) variant suitable for surface-mount assembly.
