MICROCHIP PIC18F1220 8-Bit Flash Microcontroller, SOIC-18

The MICROCHIP PIC18F1220-I/SO is a high-performance 8-bit enhanced Flash microcontroller, part of the PIC18F1x20 series. It is engineered with advanced nanoWatt technology, offering six enhanced power-managed modes for exceptional energy efficiency. This makes it ideal for battery-powered and power-sensitive applications, with consumption as low as 0.1µA in standby mode and a wide operating voltage range from 2.0V to 5.5V.

The device features a robust set of peripherals including a 10-bit Analogue-to-Digital Converter (ADC) with 7 channels, an Addressable Universal Asynchronous Receiver Transmitter (AUSART) for serial communication, and an enhanced capture/compare/PWM (ECCP) module. It includes 4KB of Flash program memory, 256 bytes of RAM, and 128 bytes of data EEPROM with a retention of over 40 years.

Key technical features include:

• Low-Power Architecture: nanoWatt technology with software-controlled sleep, idle, and power-saving modes.
• Enhanced Connectivity: EUSART interface for reliable serial data communication.
• Precision Analogue Input: 7-channel, 10-bit ADC for accurate sensor interfacing and measurement.
• High Reliability: Extended watchdog timer with a programmable period from 41ms to 131s and a fail-safe clock monitor.
• Development Friendly: Supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) via two pins, alongside a C compiler-optimised architecture.
• Robust Timing: Features a two-speed oscillator start-up and a secondary oscillator using Timer1 at 32kHz.

This surface-mount microcontroller in an SOIC-18 package is designed for demanding embedded applications, offering a powerful blend of processing capability, connectivity, and ultra-low power consumption.
