PIC16LF1789-I/MV

PIC16LF1789-I/MV is an 8‑bit Microchip PIC microcontroller in the PIC16LF1789 family. It’s designed for embedded control tasks and combines Flash program memory, RAM, and EEPROM with a rich set of peripherals.
Key features (typical for this family):
- Peripherals: 8‑ and 10‑bit ADC (multi-channel), timers, CCP/PWM, EUSART (USART), I2C (MSSP) and SPI, analog comparators.
- Power and sleep: operates from 2.0–5.5 V with low‑power modes and watchdog/brown‑out reset.
- Temperature and package: I indicates Industrial temperature range (-40°C to +85°C); MV denotes a specific package/variant option.
- Applications: sensor interfacing, motor control, data logging, and general embedded control.
