C8051F31x Small Form Factor Microcontrollers

The C8051F31x small MCU devices are available in 24-pin, 28-pin and 32-pin packages and include 16 kB flash with 10-bit ADC. A pin-for-pin compatible One-time Programmable (OTP) EEPROM version is also available (C8051T61x).

With on-chip Power-On Reset, VDD monitor, Watchdog Timer and clock oscillator, the C8051F31x devices are truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
