On-chip peripherals include a low-voltage detect (LVD), power-on reset (POR), PWM timer, and watchdog timer (WDT) — the usual set for standalone control without external supervisor ICs. The 12-channel, 12-bit ADC handles analog inputs like thermistors or potentiometers.
The 18 general-purpose I/O lines in the 16-TSSOP package leave room for a handful of sensors and actuators while keeping the BOM count low.
It is ROHS3 compliant.
No, the oscillator type is External — you must provide a clock source (crystal, resonator, or external clock) on the OSC pins.
Yes, it is ROHS3 compliant.
