4. Precision32™ SiM3L1xx System Overview
The SiM3L1xx Precision32™ devices are fully integrated, mixed-signal system-on-a-chip MCUs. Highlighted
features are listed below. Refer to Table 5.1 for specific product feature selection and part ordering numbers.
With on-chip power-on reset, voltage supply monitor, watchdog timer, and clock oscillators, the SiM3L1xx devices
are truly stand-alone system-on-a-chip solutions. The flash memory is reprogrammable in-circuit, providing non-
volatile data storage and allowing field upgrades of the firmware. User firmware has complete control of all
