PIC18F46K20-E/ML

The PIC18F46K20-E/ML is an 8‑bit Microchip microcontroller in the PIC18F46K20 family. The -E suffix indicates extended temperature operation (-40 to +85°C); the -ML suffix denotes the molded leaded package option. It is a general‑purpose controller with a rich peripheral set and flexible I/O.
Key points:
- 8‑bit core with a Harvard architecture and relatively fast operation for an MCU in this class.
- Memory: program flash, data RAM, and EEPROM for code, runtime data, and nonvolatile storage.
- Peripherals: multiple timers, CCP/PWM, capture, an—but with a 10‑bit ADC and multiple input channels, USART, SPI, I2C (MSSP), and a Peripheral Pin Select (PPS) system to map peripherals to pins.
- Power/clock: options for various oscillator configurations, with safety features like watchdog and Brown‑out Reset.
- Development: supported by MPLAB X IDE and XC8 compiler; debugging with PICKit/ICD.
Typical uses: motor control, sensor interfacing, data logging, and other embedded control tasks. For exact memory sizes, pins, and timing, consult the datasheet.
