C8051F2xx Small Form Factor Microcontrollers

The C8051F2xx is a family of fully integrated, mixed-signal system-on-a-chip small form factor microcontrollers (MCUs) available with a true 12-bit (C8051F206) multi-channel ADC, 8-bit multi-channel ADC (C8051F220/221/226 and C8051F206) or without an ADC (C8051F230/231/236). Each model features an 8051-compatible microcontroller core with 8 kB of Flash memory. There are also UART and SPI serial interfaces implemented in hardware.

Products in this family feature 22 or 32 general purpose I/O pins, some of which can be used for assigned digital peripheral interface. Any of the pins may be configured for use as analog input to the analog-to-digital converter (C8051F220/221/226 and C8051F206 only). Other features include an on-board VDD monitor, WDT, and clock oscillator. On-board Flash memory can be reprogrammed in-circuit, and may also be used for non-volatile data storage. Integrated peripherals can also individually shut down any or all of the peripherals to conserve power. All parts have 256 bytes of SRAM. An additional 1024 bytes of RAM is available in the C8051F206/226/236 devices.
