The Microchip PIC16F15345-I/P is an 8-bit PIC MCU from the PIC® XLP™ 16F series, built around a 32 MHz core with 14KB of Flash program memory and 1K x 8 of RAM. The 20-pin DIP package (20-DIP, 0.300" body) is through-hole, socket-friendly, and field-replaceable — no hot air needed.
14KB Flash and 1K RAM — sizing the firmware budget
With 14KB of Flash (8K x 14 words) and 1K x 8 of SRAM, this part targets control-loop firmware, sensor fusion, and communication stacks that fit within a modest memory footprint. The 14KB Flash is enough for a bootloader plus a moderate application layer, but if your project needs over-the-air update staging or a large lookup table, you will be bumping against the ceiling. The 1K x 8 RAM handles a few buffered UART packets and a small state machine; anything heavier — like a full TCP/IP stack — will push you to a part with more SRAM.
Industrial temp and wide supply — real-world margin
The 2.3V to 5.5V supply range means it can ride through a cold-crank dip on a 5V rail or run directly from a 3.3V LDO without a boost converter.
20-DIP through-hole — field-swappable, no bench required
The 20-pin DIP package (0.300" width, 7.62mm pitch) is a through-hole part that sockets into a standard DIP-20 socket. That means you can swap it on site with a screwdriver and a gentle pry — no soldering iron, no hot-air station.
