The PIC18F46K20-E/ML is Microchip’s mid‑range 8‑bit PIC18 microcontroller in the PIC18F46K20 family. It uses an enhanced PIC18 core, runs up to about 40 MHz (roughly 40 MIPS), and includes memory and peripherals suitable for embedded control tasks.
Key points
- Core and speed: 8‑bit PIC18 core, up to ~40 MHz operation.
- Memory: Tens of KB of flash for code, a few KB of RAM, plus EEPROM (sizes vary by package).
- Peripherals: ADC (10‑bit, multiple channels), timers, EUSART, SPI/I2C (MSSP), capture/compare/PWM (ECCP), interrupts, watchdog, and low‑voltage programming.
- Packaging: -E indicates extended (industrial) temperature range; -ML denotes a Micro Leadframe (leadless) package.
- Development: Supported by MPLAB X IDE with the XC8 compiler; program/debug with PICKit, ICD, or similar tools.
- Where to start: consult the latest datasheet for exact memory map, pinout, and package options; review programmer/debugger requirements and application notes for common peripherals.
Useful for: general embedded control, sensor interfacing, and compact, cost-sensitive applications.
