C8051F384-GQ

Overview

The Silicon Labs C8051F384-GQ is an 8-bit microcontroller featuring a high-speed 8051 core operating at up to 48 MIPS. It integrates 64 kB of in-system programmable Flash memory and 4352 bytes of RAM. The device includes a USB 2.0 compliant full-speed controller with integrated transceiver and clock recovery, eliminating the need for external components. Digital peripherals consist of two SMBus/I2C interfaces, two enhanced UARTs, one SPI interface, six 16-bit timers, and a Programmable Counter Array. Analog features include a 10-bit ADC with up to 500 ksps throughput, two comparators, and a temperature sensor. It operates on a voltage supply of 2.7 V to 5.25 V within a -40°C to +85°C temperature range.

Procurement Notes

Verify that the specific part number matches the required package type and speed grade. Confirm that the design accommodates the specified voltage range and temperature limits. Ensure compatibility with existing development tools for the C8051F family. Check for any end-of-life notices or recommended replacements from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a complete USB solution without external crystals or resistors is required. Consider the 48-pin TQFP package for sufficient I/O availability. Evaluate the 4352-byte RAM size against application requirements. Verify that the 10-bit ADC resolution meets signal processing needs. Ensure the 48 MHz clock speed aligns with real-time processing constraints.

Part Context

This device belongs to the C8051F38x family of Full Speed USB Flash MCUs. It shares architectural similarities with other members like the C8051F380 and C8051F382 but differs in memory configuration and pin count. The family utilizes a pipelined instruction set and supports in-system programming via standard serial interfaces.

Replacement Considerations

Public confirmed substitute part numbers: C8051F380-GQ, C8051F382-GQ, C8051F386-GQ.
