PIC16F1937-I/ML

PIC16F1937-I/ML is an 8‑bit Microchip PIC microcontroller from the PIC16F193x family. The I/ML suffix indicates industrial‑temperature operation in a molded leaded package (ML).
Key points:
- Classic PIC16F core with efficient instruction set and multiple low‑power modes.
- On‑chip peripherals: multi‑channel ADC, timers, capture/compare/PWM, and serial communications (USART/EUSART, SPI, I2C/MSSP).
- Memory: flash program memory, RAM, and non‑volatile EEPROM for data storage.
- Robustness: brown‑out reset, watchdog timer, and selectable code protection options.
- Clocking: supports internal oscillator or external clock/crystal.
- Development: supported by MPLAB X IDE and XC8 compiler; programming via ICSP.
Typical uses: sensor interfacing, data logging, small motor/actuator control, and general industrial control tasks in a compact, cost‑conscious package. For exact memory sizes, peripherals, and pin counts, consult the datasheet.
