C8051F33x Small Form Factor MCUs

C8051F33x Small Form Factor MCU Block Diagram

The C8051F33x small MCU devices are available in 20-pin and 24-pin packages and include up to 16 kB flash with 10-bit ADC and 10-bit DAC. A pin-for-pin compatible one-time Programmable (OTP) EEPROM version is also available (C8051T63x).

With on-chip Power-On Reset, VDD monitor, Watchdog Timer and clock oscillator, the C8051F33x devices are truly stand-alone System-on-a-Chip solutions. The Flash memory of these small MCUs can be reprogrammed even in-circuit, providing non-volatile data storage, and also allows 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 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 (–40 to +85 °C).
