C8051F412-GQ

Overview

The C8051F412-GQ is an 8-bit microcontroller from the Silicon Labs C8051F41x family, housed in a 32-pin LQFP package. It features a high-speed 8051 core operating at up to 50 MHz with 50 MIPS throughput. The device includes 16 kB of Flash memory and 2304 bytes of internal data RAM. Analog peripherals consist of a 12-bit ADC with up to 24 external inputs and two 12-bit current-mode DACs. It supports a supply voltage range of 2.0 V to 5.25 V and operates within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrated 12-bit analog-to-digital converter with programmable throughput and windowed interrupt generation capabilities.
• Dual 12-bit current-mode digital-to-analog converters for precise signal output control.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Hardware smaRTClock providing real-time clock functionality with battery-backed RAM and backup voltage regulator.

Applications

• Voice recorder circuits utilizing hardware accumulation and burst mode for audio processing
• Mixed-signal system-on-a-chip solutions requiring standalone operation
• Applications needing low-power suspend modes with wake-up capability

Procurement Notes
