C8051T630DB20

System Overview

C8051T600/1/2/3/4/5 devices are fully integrated mixed-signal System-on-a-Chip MCUs. Highlighted features are listed below. Refer to Table 1.1 on page 14 for specific product feature selection.
With on-chip Power-On Reset, Supply Monitor, Watchdog Timer, and clock oscillator, the C8051T600/1/2/3/4/5 devices are truly stand-alone System-on-a-Chip solutions. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
