What are the key features of PIC18F2553-I/SP?
- Full-speed USB 2.0 device interface built in, enabling direct PC connectivity without an external USB-to-serial bridge chip
- 32KB Flash and 2048B RAM with 48 MHz maximum clock for USB-demanding applications in a 28-pin through-hole DIP package
- 10-channel 10-bit ADC plus SPI, I2C, and USART for versatile mixed-signal and communication tasks in a single IC
What is PIC18F2553-I/SP used for?
The PIC18F2553-I/SP is designed for USB-connected embedded applications such as HID keyboards, custom USB data acquisition devices, and USB-to-sensor interface adapters that benefit from direct PC connectivity. Its 32KB Flash and 2048B RAM support moderately complex USB descriptor stacks alongside application firmware. The 28-pin SPDIP through-hole format is popular in prototyping, educational labs, and low-volume production boards where soldering ease matters.

Frequently Asked Questions
Which USB speed class does PIC18F2553-I/SP support, and how does that affect PC enumeration?
PIC18F2553-I/SP supports full-speed USB 2.0 at 12 Mbps, which is the standard speed for HID, CDC, and custom bulk transfer classes. This allows the device to enumerate as a virtual COM port, HID joystick, or generic vendor class on any modern PC without installing drivers beyond standard OS class drivers.
For a benchtop data-logger prototype using PIC18F2553-I/SP, how many analog channels can be sampled simultaneously?
The PIC18F2553-I/SP includes a 10-channel, 10-bit ADC capable of multiplexed sampling across up to 10 analog input pins. While only 1 channel converts at a time through the on-chip MUX, burst sampling across all 10 channels at 48 MHz clock yields effective throughput sufficient for audio-rate or slow sensor aggregation in data-logger designs.
When is PIC18F2553-I/SP in SPDIP-28 a practical alternative to a surface-mount variant for low-volume builds?
The SPDIP-28 through-hole package allows hand-soldering and breadboard prototyping without reflow equipment, making PIC18F2553-I/SP cost-effective for batches under 500 units or lab setups. The 28-pin DIP socket also enables in-system chip swapping for debugging, a significant advantage over SOIC or QFN variants in educational or repair contexts.
