Applications
The PIC18F2620-I/SP is used in embedded sensing and control applications such as environmental monitors, temperature data loggers, and HVAC controllers that require a compact 8-bit MCU with multiple ADC channels and serial communication interfaces. It serves robotics and motor control projects where the 40 MHz PIC18 core provides sufficient processing throughput for PID loop execution and PWM generation using the on-chip CCP modules. The device is also popular in educational platforms and hobbyist projects because the 28-pin SPDIP package works directly in standard breadboards and DIP sockets without specialized soldering equipment.

Frequently Asked Questions
How much program memory and RAM does the PIC18F2620-I/SP provide, and what size of firmware can it run?
The PIC18F2620-I/SP includes 64 kB of flash program memory and 3968 bytes of SRAM, which is sufficient for complex control firmware including lightweight protocol stacks such as Modbus RTU or CAN-over-UART. The 64 kB flash accommodates MikroC, XC8, or assembly programs with lookup tables, sensor calibration data, and multiple communication handlers simultaneously.
Which analog and digital peripherals are integrated into the PIC18F2620-I/SP for sensor-based designs?
The PIC18F2620-I/SP integrates a 10-bit ADC with up to 13 analog input channels, two CCP modules for PWM and capture functions, a hardware USART for RS-232 or RS-485 communication, and a MSSP module supporting both SPI and I2C protocols. This peripheral set allows simultaneous multi-channel analog sampling at 25 ksps and serial data transfer without requiring external interface ICs, reducing BOM cost in temperature or pressure monitoring designs.
Can the PIC18F2620-I/SP operate from a single AA or AAA battery cell, and how does supply voltage affect performance?
At 4 MHz clock speed, the PIC18F2620-I/SP operates from a supply as low as 2.0 V, which is within the usable range of a single AA alkaline cell from 1.5 V fresh down to about 1.8 V discharged. At full 40 MHz operation, the minimum supply rises to 4.2 V, so two AA cells in series or a regulated 3.3 V or 5 V supply is required for maximum performance, enabling designers to trade off speed for battery longevity in low-power sensor nodes.
When is the PIC18F2620-I/SP in a 28-pin SPDIP preferred over a smaller QFN-packaged MCU with similar specifications?
The SPDIP-28 package is preferred during prototyping because it plugs directly into breadboards and ZIF sockets, making it easy to swap devices and reprogram via ICSP without soldering. In field-serviceable industrial equipment where maintenance technicians replace MCUs without reflow equipment, a socketed SPDIP-28 allows 30-second device replacement compared to the hot-air rework required for QFN packages, justifying the larger 13 mm x 30 mm board footprint.
