C8051F330R

Overview

The C8051F330R is an 8-bit mixed-signal microcontroller from Silicon Labs, featuring a high-speed pipelined 8051 core operating at up to 25 MIPS. It integrates 8 kB of ISP Flash memory and 768 bytes of internal data RAM. The device includes a 10-bit ADC with up to 200 ksps throughput and 16 external inputs, alongside a 10-bit current output DAC. It operates on a supply voltage between 2.7 V and 3.6 V within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated 10-bit analog-to-digital converter supporting multiple input configurations and built-in temperature sensing capabilities.
• On-chip debug circuitry enabling full-speed, non-intrusive in-system debugging without requiring external emulator hardware.
• Hardware-enhanced serial communication interfaces including UART, SMBus, and SPI for robust digital connectivity.
• Programmable Counter Array (PCA) providing capture/compare modules and pulse width modulation functionality.

Applications

• Portable physiological parameter monitoring systems
• Magnetic stripe readers for point-of-sale terminals
• Key card reader applications
• Amateur radio transceiver designs

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm tape-and-reel packaging status. Confirm that the component remains suitable for new designs, as certain variants in this family may carry end-of-life notices. Ensure compatibility with required voltage levels and interface protocols before finalizing procurement.

Selection Notes

Select this component when a fully integrated mixed-signal solution is required within a compact footprint. It is appropriate for designs needing precise analog acquisition combined with standard digital control logic. Consider the available I/O count and peripheral set against system requirements to ensure no external components are necessary for basic operation.

Part Context

This part belongs to the C8051F33x family of system-on-chip microcontrollers. These devices are designed to replace discrete analog and digital components by integrating them onto a single silicon die. The family shares common architectural features while varying in memory size and peripheral availability.
