C8051F41x Small MCU Block Diagram

​The C8051F41x small MCU family is the most analog-intensive small form factor MCU on the market. This small MCU has 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 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.

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 programming and debugging without occupying package pins.
