C8051F330-GDI

Overview

The C8051F330-GDI is a mixed-signal ISP Flash microcontroller from Silicon Labs, featuring an 8-bit CIP-51 core with up to 25 MIPS throughput. It includes 8 kB of in-system programmable Flash memory and 768 bytes of internal data RAM. The device integrates a 10-bit ADC with up to 16 external single-ended or differential inputs, a 10-bit current output DAC, and a voltage comparator. Digital peripherals include hardware-enhanced UART, SMBus, SPI, four 16-bit timers, and a Programmable Counter Array. It operates on a 2.7 V to 3.6 V supply within the -40 °C to +85 °C temperature range.

Feature Summary

• Integrates a high-speed pipelined 8051-compatible core for efficient instruction execution.
• Includes analog peripherals such as a 10-bit ADC, 10-bit current output DAC, and voltage comparator.
• Features on-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without external emulators.
• Provides flexible digital I/O with 5 V tolerant ports and multiple serial communication interfaces.

Applications

• Industrial control systems requiring mixed-signal processing
• Data acquisition applications utilizing onboard ADC and temperature sensors
• Embedded systems needing in-system programming capabilities

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific GDI suffix indicates bare die configuration if required by your assembly process. Review the official datasheet for absolute maximum ratings and handling precautions associated with exposed die packages. Ensure compliance with RoHS and REACH regulations applicable to your region before finalizing procurement.

Selection Notes

Select this model when a fully integrated mixed-signal solution is required alongside a standard 8051 architecture. The inclusion of both ADC and DAC distinguishes it from other variants in the F33x family that may lack one or both converters. Consider the 20-pin QFN package constraints and verify pinout compatibility with your PCB layout. Evaluate power consumption requirements against the typical operating currents specified at various clock frequencies.

Part Context

This component belongs to the C8051F33x series of mixed-signal system-on-chip microcontrollers. These devices are designed to reduce component count and board space by integrating extensive analog and digital peripherals onto a single silicon die. The series supports rapid development through in-system programming and comprehensive on-chip debugging tools provided by Silicon Labs.

Replacement Considerations

Consult the official product selection guide for alternative part numbers within the C8051F33x family. Verify peripheral availability, specifically checking for the presence of the 10-bit ADC and DAC which are unique to certain variants like the F330. Ensure any substitute maintains the same package type and electrical specifications for direct integration.
