The PIC16F1613-I/P is an 8-bit PIC MCU from Microchip's PIC® XLP™ 16F family, clocked at 32 MHz. That 32 MHz is the internal oscillator speed — no external crystal needed, which saves two pins and a board footprint. The core executes most single-cycle instructions, so the effective throughput is close to 8 MIPS at 32 MHz. For a small control loop — say, a PWM fan controller or a sensor hub reading an 8x10-bit ADC — this is enough headroom without overclocking.
3.5 KB Flash and 256 bytes RAM — sizing the firmware
Program memory is 3.5 KB organized as 2K x 14 words. That's a tight fit: enough for a bootloader plus one application task, but not for a full protocol stack. The 256 x 8 RAM handles a handful of 16-bit variables and a small stack.
14-DIP through-hole — board fit and repair reality
The 14-DIP (0.300", 7.62mm) package is through-hole. That means it plugs into a socket or solders into plated through-holes — no reflow profile, no stencil. For a repair bench, this is the part you can swap in five minutes with a desoldering station. For a production board, it takes up more board area than an SOIC-14, but it's easier to hand-assemble and rework.
The temperature grade covers most industrial and automotive cabin environments — not under-hood, but fine for a motor drive controller or a PLC I/O module.
