C8051F382-GQR

Overview

The C8051F382-GQR is an 8-bit mixed-signal microcontroller from the Silicon Labs C8051F38x family, housed in a 48-pin TQFP package. It features a high-speed 8051 core operating at up to 48 MIPS with pipelined architecture. The device integrates 32 kB of in-system programmable Flash memory and 2.25 kB of RAM. Key peripherals include a full-speed USB 2.0 function controller with integrated transceiver and clock recovery, a 10-bit ADC supporting up to 500 ksps, two comparators, multiple serial interfaces (SPI, I2C/SMBus, UART), and six general-purpose timers. It operates on a voltage supply of 2.7 V to 5.25 V within a temperature range of –40 °C to +85 °C.

Feature Summary

• Integrates a full-speed USB 2.0 function controller with an on-chip transceiver and clock recovery, eliminating the need for external crystals or resistors.
• Features a high-performance 8051 core capable of up to 48 MIPS execution speed with a pipelined instruction architecture.
• Includes a 10-bit analog-to-digital converter with up to 500 ksps sampling rate and built-in analog multiplexer for single-ended and differential modes.
• Provides comprehensive digital connectivity through hardware-enhanced SPI, dual I2C/SMBus ports, and enhanced UARTs.

Applications

• Embedded USB connectivity devices requiring host or peripheral communication
• Data acquisition systems utilizing the high-speed ADC and analog peripherals
• Industrial control applications needing robust digital I/O and timer functions
• Portable instruments benefiting from low-power management modes

Procurement Notes

Verify the specific suffix GQR corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the component status aligns with long-term availability plans, as this series may be subject to lifecycle changes. Ensure design compatibility with the 48-pin TQFP footprint and validate voltage regulator configurations for your target power supply range.

Selection Notes

Select this model when a compact 48-pin solution with integrated USB functionality is required without external passive components. Consider the 32 kB Flash capacity against application code size requirements. Evaluate the 10-bit ADC resolution and speed against sensor interface needs. Verify that the 2.7 V to 5.25 V operating range matches the system power rails and that the 48 MIPS performance meets real-time processing demands.

Part Context

This component belongs to the C8051F38x series of mixed-signal microcontrollers designed for embedded USB applications. It shares architectural similarities with the C8051F34x series but offers optimized integration for USB connectivity. The device combines a standard 8051 core with extensive on-chip analog and digital peripherals, targeting cost-sensitive designs that require high integration levels in a small form factor.
