PIC18F87K90T-I/PT

Introduction: The PIC18F87K90T-I/PT is an 8‑bit Microchip PIC microcontroller in the PIC18F87K90 family, aimed at embedded control and sensing tasks. The -I/PT suffix indicates packaging and temperature options (industrial temperature in a plastic package, often with Tape & Reel; verify exact options in the datasheet).
What it offers (high level):
- Core and memory: PIC18F-style 8‑bit core with on‑chip Flash (program) and RAM, plus EEPROM for data storage. Exact sizes vary by device variant and package.
- Peripherals: multiple timers (including 16‑bit), PWM/CCP modules, ADC with several channels, comparators; serial communications (USART/UART, SPI, I2C); additional capture/compare/event modules; watchdog and low‑power modes.
- I/O: configurable I/O ports with interrupt options and pullups.
- Debugging/programming: ICSP for programming; supported by MPLAB X IDE and XC8 compiler.
Common use cases: industrial automation, automotive interfaces, motor control, data acquisition, and sensor interfacing.
Getting started: consult the exact datasheet for memory/peripheral counts for your package; use MPLAB X IDE with XC8 (or XC8/XC16) toolchain; verify voltage, timing, and pinout before development.
