C8051F37x/39x Small Form Factor MCUs

The C8051F37x/9x family is the next generation of Silicon Labs’ best-selling C8051F33x mixed-signal MCUs. These MCUs range in flash size from 4-16 kB and are footprint and code compatible with the field-proven C8051F33x devices while offering faster speed/performance, more RAM, extra features and an extended temperature range.
With on-chip Power-On Reset, VDD monitor, Watchdog Timer, and clock oscillator, the C8051F37x/39x 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.
