C8051F133 Description

Short technical summary and product information.

The C8051F133 is an 8-bit, analog-intensive mixed-signal microcontroller from Silicon Labs based on a pipelined 8051 core running at up to 100 MHz. It provides 64 KB of in-system programmable Flash memory and 8.25 KB of internal RAM, along with 32 I/O lines and digital peripherals including SMBus (I2C-compatible), SPI, and UART/USART interfaces.

 

The device integrates a 10-bit, 8-channel ADC with 100 ksps throughput, two comparators, and a built-in temperature sensor. Additional analog and system functions include a brown-out detector/reset, power-on reset, PWM, and watchdog timer. The MCU operates from a 3.0 V to 3.6 V supply at 100 MHz and is specified over a -40°C to 85°C operating temperature range.

 

The C8051F133 is housed in a 64-TQFP package measuring 10x10 mm with surface-mount mounting, making it suitable for compact embedded systems. An internal 24.5 MHz oscillator and on-chip VDD monitor reduce external component count, while the external memory interface (EBI/EMI) offers additional system flexibility.

 

Silicon Labs has announced End of Life (EOL) for this device and recommends the EFM8BB31F64G-QFN32 as a replacement. Typical applications noted by the manufacturer include portable medical equipment, weigh scales, test equipment, and fiber optic systems.
