The C8051F343-GQR is an 8-bit microcontroller from Silicon Laboratories based on the 8051 core. It is part of the C8051F34x family and designed for embedded systems requiring USB connectivity.
The device operates from 2.7V to 5.25V supply voltage. It features a 10-bit ADC with 21 input channels and sampling rates up to 200 ksps. The USB 2.0 controller supports full-speed (12 Mbps) or low-speed (1.5 Mbps) operation with eight flexible endpoints and integrated clock recovery, eliminating the need for an external crystal.
The MCU includes 32KB of in-system programmable flash memory, 2.25KB RAM, and a 48MHz 8051 core that executes 70% of instructions in one or two system clocks. Digital peripherals include SMBus, SPI, UART/USART, USB, four 16-bit timers, a programmable counter array with five capture/compare modules, and 25 I/O lines. On-chip debug provides full-speed non-intrusive in-system debugging.
The C8051F343-GQR is supplied in a 32-pin LQFP package (7x7 mm) for surface mount. It operates over a -40°C to 85°C temperature range, making it suitable for a variety of industrial and consumer applications.
The supply voltage range is 2.7V to 5.25V, with 3.6V to 5.25V supported using the on-chip voltage regulator.
The device is available in a 32-LQFP package, measuring 7x7 mm, for surface mount.
-40°C to 85°C (TA).
The database lists RoHS3 compliant status, but this is unverified and low confidence.
The device uses an 8051 core with a maximum speed of 48MHz.
It has 32KB in-system programmable flash memory and 2.25KB RAM.
USB 2.0 compliant with full-speed (12 Mbps) or low-speed (1.5 Mbps) operation, eight flexible endpoints, and integrated clock recovery.
