C8051F30x Small Form Factor Microcontrollers

The C8051F30x small MCU devices were the world’s first MCU to fit in a tiny 3 mm x 3 mm package. There are no compromises on integration and performance with a 25 MIPS CPU, 500 ksps 8-bit ADC, on-chip (±2%) precision oscillator and comparator. A pin-for-pin compatible One-time Programmable (OTP) EEPROM version is also available (C8051T60x).
With on-chip Power-On Reset, VDD monitor, Watchdog Timer and clock oscillator, the C8051F300/1/2/3/4/5 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.

    The on-chip Silicon Labs' 2-Wire (C2) Development Interface allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping and run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging without occupying package pins.
    Each device is specified for 2.7 to 3.6 V operation over the industrial temperature range (–45 to +85 °C). The Port I/O and RST pins are tolerant of input signals up to 5 V. The C8051F300/1/2/3/4/5 devices are available in the RoHS compliant 11-pin QFN package.
