C8051F35x Analog-Intensive MCUs

The C8051F35x mixed-signal 8-bit microcontroller (MCU) devices include a 16-bit or 24-bit sigma-delta ADC subsystem. The sub-system allows up to eight input channels with a programmable gain stage of up to 128 times. Two separate 8-bit DACs are also included.

With on-chip power-on reset, VDD monitor, watchdog timer and clock oscillator, the C8051F350/1/2/3 microcontroller 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.
