The C8051F851-C-GU is an 8-bit microcontroller from Silicon Labs. It is a member of the C8051F850 family of MCUs. This specific part features a fully integrated 8051 core, up to 32kB of on-chip Flash, up to 512 bytes of RAM and a range of peripherals. The package is a 28-pin TSSOP (Thin Shrink Small Outline Package) with a Power Supply Voltage range of 2.7–3.6V. The C8051F851-C-GU offers a high level of integration, including 14 channels of 10-bit analog-to-digital conversion, two PWM output channels, two high-speed counter/timers, and two enhanced compare/capture/PWM (ECPWM) modules. Additionally, the C8051F851-C-GU has an intelligent power-management system, low power sleep mode and smart peripheral scaling. The C8051F851 has a fast instruction cycle time of 12 clock cycles at 12 MHz, allowing for efficient and powerful signal processing. These features make the C8051F851-C-GU well-suited for peripherals and consumer electronics which require fast signal processing, analog-to-digital conversion and low power consumption.
