C8051T321-GMR Description

Short technical summary and product information.

The C8051T321-GMR is an 8-bit microcontroller from Silicon Labs based on a high-speed pipelined 8051 core. It delivers up to 48 MIPS throughput with a 48 MHz internal oscillator. The device includes 16KB of one-time programmable (OTP) EPROM code memory and 1.25K x 8 bytes of internal RAM.

 

This MCU integrates a 10-bit ADC with up to 21 external inputs and a built-in temperature sensor. Connectivity options include I²C, SPI, UART/USART, and a USB 2.0 compliant full-speed function controller. Peripherals include power-on reset (POR), PWM, a temperature sensor, and a watchdog timer (WDT).

 

The C8051T321-GMR is supplied in a 28-VFQFN exposed pad package (28-QFN 5x5 mm) for surface mount assembly. It operates from a 1.8V to 5.25V supply and over a -40°C to +85°C temperature range.
