概述

Description

The PIC16F1938T-I/SO is Microchip’s 8‑bit PIC16F1 family microcontroller, offered in a 14‑pin SOIC with industrial temperature range (I/SO). It’s designed for small embedded tasks with a compact package and integrated peripherals.
Key points:
- Core and memory: 8‑bit PIC core with on‑chip Flash, RAM, and EEPROM (sizes suitable for simple apps).
- Peripherals: ADC (10‑bit) with multiple channels, timers, and a watchdog; PWM outputs for control and signaling.
- Serial and buses: EUSART (USART), I2C (MSSP), SPI for serial comms.
- I/O and routing: Peripheral Pin Select (PPS) to map peripherals to I/O pins.
- Power and sleep: internal oscillator, low‑power modes, brown‑out reset.
- Programming/debug: ICSP for programming and debugging; MPLAB X IDE with XC8 compiler.
Applications: small sensors, control loops, user interfaces, and other compact embedded tasks. For exact memory sizes, pin count, and peripheral details, consult the datasheet.
