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.
The supply voltage range is 3.0V to 3.6V at 100MHz operation, with a wider 2.7V to 3.6V range at 50 MIPS.
It is available in a 64-TQFP (10x10mm) surface-mount package.
-40°C to 85°C (TA).
It is listed as RoHS3 Compliant in the existing database, but this compliance status has not been externally verified.
The maximum speed is 100MHz, supporting up to 100 MIPS throughput.
It has 64KB of Flash program memory and 8.25KB of internal RAM.
