PIC18F66K80-I/MR

The PIC18F66K80-I/MR is an 8‑bit Microchip PIC microcontroller in the PIC18F66K80 family. The -I suffix denotes Industrial temperature range (−40 °C to 85 °C); the -MR suffix indicates a reel/tape packaging option for manufacturing.
Key features (typical): up to 40 MHz oscillator (≈10 MIPS), 64 KB Flash program memory, RAM and EEPROM for data storage, and a rich peripheral set. Peripherals commonly include: ADC (10‑bit, multiple channels), multiple timers, USART/EUSART, SPI and I2C (MSSP), CCP/PWM modules, and Peripheral Pin Select (PPS) for flexible I/O mapping. Includes watchdog timer, brown-out reset, low‑power sleep modes, and code protection.
Power and packaging: operates on 2.0–5.5 V; available in 28/40‑pin packages, with industrial temperature range in MR packaging.
Applications: general embedded control, sensor interfacing, automation, motor control, and other cost‑sensitive embedded tasks.
Development: supported by Microchip MPLAB X IDE with XC8 compiler; programming/debug via PICkit 3/4, ICD, or other Microchip debuggers.

Direct equivalents from other vendors do not exist. The closest substitutes are other Microchip PIC18F66K80 variants with different packaging suffixes (e.g., PIC18F66K80-I/SN, PIC18F66K80-I/ML). Use Microchip’s cross-reference tool or distributors to identify exact packaging equivalents. If a non-Microchip option is required, choose devices with roughly 64 KB program flash and similar peripherals (USART, MSSP, A/D).
