The Silicon Labs C8051F321-GMR is an 8-bit microcontroller from the C8051F32x family, built around a high-speed pipelined 8051 core. It operates at up to 25 MHz, delivering 25 MIPS throughput. The device includes 16 KB of in-system programmable Flash memory and 2.25 KB of internal RAM, which includes a 1 KB USB FIFO buffer.
This MCU integrates a full-speed USB 2.0 controller supporting both 12 Mbps and 1.5 Mbps operation, with an internal oscillator that achieves 0.25% accuracy when clock recovery is enabled. A 10-bit ADC with up to 200 ksps sampling rate provides up to 13 external single-ended or differential inputs, along with an internal temperature sensor.
Connectivity options include SMBus (I2C), SPI, enhanced UART, and USB. Peripheral features include four 16-bit timers, a programmable counter array (PCA) with five capture/compare modules, PWM, brown-out detect, power-on reset, and a watchdog timer. The device operates from a 2.7V to 3.6V supply and can tolerate an input voltage of 4.0V to 5.25V on the voltage regulator input.
The C8051F321-GMR is supplied in a 28-pin MLP (5x5 mm) package with an exposed pad for thermal management, rated for surface mount assembly. It operates over the industrial temperature range of -40°C to 85°C. The component is RoHS compliant and lead-free, packaged in tape and reel with a standard quantity of 1500 units.
The supply voltage range is 2.7V to 3.6V, with a voltage regulator input of 4.0V to 5.25V.
It comes in a 28-pin MLP (5x5 mm) surface mount package with exposed pad (28-VFQFN Exposed Pad).
The operating temperature range is -40°C to 85°C.
The component is marked as RoHS3 compliant and lead-free, but this status is unverified. Refer to the manufacturer for official certification.
The maximum clock speed is 25 MHz, yielding up to 25 MIPS throughput.
It has 16 KB of Flash memory, organized as 16K x 8, in-system programmable in 512-byte sectors.
Yes, it includes a USB 2.0 compliant controller supporting full speed (12 Mbps) and low speed (1.5 Mbps) operation with integrated clock recovery.
