The C8051F00x-01x family devices are highly integrated mixed-signal MCUs featuring a true 10 or 12-bit multi-channel ADC and two separate 12-bit DACs, two voltage comparators (F002/07/12/17 have one only), a voltage reference, and an 8051-compatible microcontroller core with 32 kB of FLASH memory. There are also I2C/SMBus, UART, and SPI serial interfaces implemented in hardware as well as a Programmable Counter/Timer Array (PCA) with five capture/compare modules. As well as four general-purpose 16-bit timers and 4 byte-wide general-purpose digital Port I/O. The F000/01/02/10/11/12 have 256 bytes of RAM and execute up to 20 MIPS, while the F005/06/07/15/16/17 have 2304 bytes of RAM and execute up to 25 MIPS.
With an on-board VDD monitor, WDT, and clock oscillator, the MCUs are truly stand-alone System-on-a-Chip solutions. Each MCU effectively configures and manages the analog and digital peripherals. The FLASH memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. Additionally, each MCU can individually shut down any or all of the peripherals to conserve power.
