PIC16F1937-I/ML

The PIC16F1937-I/ML is Microchip’s 8‑bit PIC18/16 family microcontroller aimed at simple to mid‑range embedded control. The -I/ML suffix indicates Industrial temperature range with a Molded Leadframe (ML) package; exact package count (often 28‑pin in practice) should be confirmed in the datasheet.
Key points:
- On‑chip memory: Flash for program storage, RAM, and often EEPROM for data.
- Peripherals: multiple timers, analog-to-digital converter, comparators, and communication modules (USART/EUSART with SPI/I2C via MSSP), plus capture/compare/PWM as needed.
- Core and performance: 8‑bit PIC core with a compact instruction set optimized for control tasks.
- Power and clocks: operate from roughly 2.0 to 5.5 V; various clock options (internal oscillator or external crystal/ceramic resonator); sleep/idle modes for low power.
- Development: supported by MPLAB X IDE, XC8 compiler, and debugging/prototyping tools (e.g., PICkit).
Typical use: general purpose microcontroller for embedded applications in industrial, consumer, and small automation. For exact features and package options, consult the PIC16F1937 datasheet.
