PIC18F2420 8Bit Flash MCU, SOIC28, 16KB, 40MHz

The PIC18F2420-I/SO is a high-performance 8-bit Flash microcontroller from Microchip, featuring an enhanced architecture with nanoWatt technology for power-sensitive applications. With up to 10 MIPS performance and a C compiler-optimised RISC core, this device is designed for demanding embedded control tasks while minimising energy consumption.

This MCU integrates a range of features to simplify design and reduce system cost. The internal oscillator block can generate two different clock signals, eliminating the need for external oscillator circuits on the OSC1 or OSC2 pins. The device can be serially programmed in-circuit using just two lines for clock and data, plus power, ground, and programming voltage, enabling flexible firmware updates.

Key Features

• Up to 10 MIPS performance with C compiler-optimised RISC architecture
• nanoWatt power-managed modes: Run, Idle, and Sleep
• Watchdog timer with separate RC oscillator for reliable operation
• 10-channel 10-bit A/D converter with 100kSPS sampling rate
• Programmable brown-out reset module for system stability
• 100 years typical Flash/Data EEPROM retention for long-term data storage
• Self-programmable under software control for field updates
• Priority levels for interrupts for responsive handling
• 8x8 single-cycle hardware multiplier for fast maths
• In-Circuit Debug (ICD) via two pins for easy development

The PIC18F2420 is available in a 28-pin SOIC package, with 25 I/Os and support for EUSART, I2C, and SPI interfaces. Operating from 4.2V to 5.5V and across -40°C to 85°C, this microcontroller is suitable for a wide range of industrial and consumer applications.
