Description
PIC16F1938T-I/SO is an 8‑bit Microchip PIC16F microcontroller in an industrial-temperature, SOIC package. It belongs to the PIC16F family and is intended for small‑to‑mid‑scale embedded control tasks. Key features (high level) include: on‑chip flash program memory, RAM, and EEPROM; a rich set of peripherals such as ADC(s) with multiple channels, comparators, timers, PWM/CAP modules, and serial communication interfaces (USART/UART, SPI, I2C); numerous I/O pins for sensor/actuator interfacing; and in‑circuits programming via ICSP. Typical operation supports moderate supply voltages and various low‑power modes. Development is supported by Microchip MPLAB X IDE and the XC8 compiler, with extensive documentation and example code. Common use cases are simple controllers, data acquisition, display driving, and small appliance control. For exact memory size, pin count, voltage range, and peripheral details, consult the PIC16F1938 datasheet and the -I/SO package specifications.
