C8051F41x Small Form Factor Microcontrollers
The C8051F41x small microcontroller (MCU) family is the most analog-intensive small form factor MCU on the market. The C8051F41x small MCUs have an integrated 24-channel 12-bit ADC and dual 12-bit DACs. These mixed-signal microcontrollers include up to 32 kB of flash with 2 kB RAM in a 5 mm x 5 mm package.
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and a clock oscillator, the C8051F41x devices are truly standalone 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.
