C8051F830-GS

Overview

The C8051F830-GS is a mixed-signal ISP Flash MCU from the C8051F80x-83x family. It features a high-speed 8051 core with up to 25 MIPS throughput at a 25 MHz clock. Memory includes up to 16 kB of in-system programmable Flash and 512 bytes of internal data RAM. Analog peripherals consist of a 10-bit ADC supporting up to 500 ksps, a comparator, and a Capacitance to Digital Converter (CapSense) with 16-bit resolution. Digital interfaces include an enhanced UART, SMBus, SPI, three 16-bit timers, and a PCA with PWM functionality. The device operates on a supply voltage of 1.8 to 3.6 V and supports packages such as 24-pin QSOP, 20-pin QFN, and 16-pin SOIC.

Procurement Notes

Verify component authenticity through authorized Silicon Labs distributors or direct channels. Confirm package type and temperature range specifications match design requirements. Note that this product family is marked as Not Recommended for New Designs; evaluate long-term availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this model when a fully integrated mixed-signal solution with capacitive sensing capabilities is required within a constrained form factor. Ensure compatibility with existing 8051-based software architectures due to the CIP-51 core. Consider the limited I/O count and specific peripheral set against application needs, particularly regarding the absence of USB connectivity found in other series.
