The C8051F021 is a highly integrated mixed-signal 8-bit microcontroller from Silicon Labs, part of the C8051F02x family. It features a powerful 8051 core operating at up to 25 MHz, delivering 25 MIPS throughput. The device includes 64 KB of Flash program memory and 4.25 KB of RAM. Analog peripherals include a 12-bit SAR ADC with up to 100 ksps sampling rate and 8 external inputs, two 12-bit DACs, and two analog comparators. Digital peripherals include 32 I/O lines, SMBus (I2C), SPI, and two UART serial interfaces, along with a 16-bit timer array with 5 capture/compare modules. The microcontroller operates from 2.7V to 3.6V and over a temperature range of -40°C to 85°C. It is housed in a 64-TQFP (10x10 mm) surface-mount package. On-chip JTAG debug and boundary scan provide full-speed, non-intrusive debugging. The C8051F021 is suitable for applications such as portable medical equipment, weigh scales, test equipment, and fiber optic systems. Note: This part is End of Life (EOL); Silicon Labs recommends the EFM8BB31F64G-QFN32 as a replacement.
