C8051F382-GQ

Overview

The C8051F382-GQ is an 8-bit microcontroller from the Silicon Labs C8051F38x family, featuring a high-speed 48 MIPS 8051 core. It integrates 32 kB of in-system programmable Flash memory and 2.25 kB of RAM. The device includes a Full Speed USB 2.0 controller with integrated transceiver and clock recovery, eliminating the need for external components. Analog peripherals consist of a 10-bit ADC supporting up to 500 ksps, two comparators, and a built-in temperature sensor. It operates on a voltage supply of 2.7 V to 5.25 V and is housed in a 48-pin TQFP package.

• Integrated Full Speed USB 2.0 controller with internal clock recovery and transceiver
• High-performance pipelined 8051 core executing instructions in 1 or 2 system clocks
• On-chip debug circuitry enabling non-intrusive in-system debugging without external emulators
• Versatile analog subsystem including a 10-bit ADC with multiplexer and dual comparators

Applications

• Medical diagnostic equipment requiring USB connectivity and high-performance analog processing
• Point-of-sale (POS) terminals needing robust data communication interfaces
• Embedded modems utilizing serial communication protocols
• Voice over Internet Protocol (VoIP) telephones integrating USB and audio sensing

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the C8051F38x series utilizes distinct packages like TQFP-48 and LQFP-32. Confirm that the selected variant aligns with the necessary memory capacity and peripheral set defined in the official datasheet. Ensure compliance with RoHS standards and check for any product change notices regarding availability or manufacturing updates before finalizing procurement.

Selection Notes

Select this component when a design requires a complete USB solution without external transceivers or crystals. The C8051F382-GQ is suitable for applications demanding high-speed digital processing alongside precise analog signal acquisition. Consider the 48-pin TQFP package constraints for PCB layout. Evaluate the power consumption requirements against the supported voltage range and available low-power modes such as idle and stop modes.

Part Context

This part belongs to the C8051F38x family of mixed-signal microcontrollers designed for cost-sensitive and high-performance USB applications. The family shares a common architecture but varies in memory size, package options, and specific peripheral configurations. The C8051F382 variant specifically targets designs requiring 32 kB of Flash and the 48-pin form factor, distinguishing it from other members like the C8051F381 which uses a 32-pin package.

Replacement Considerations

Direct substitutes within the same family include the C8051F380, C8051F384, and C8051F386, which share the 48-pin TQFP package and similar peripheral sets but differ in Flash memory capacity. Verify pin compatibility and software register mapping when migrating between these variants to ensure seamless integration.
