The Microchip PIC16F18075-I/PT is an 8-bit PIC® 16F microcontroller that runs at 32 MHz and operates from a single supply rail between 1.8V and 5.5V. The 14 KB Flash program memory and 1K × 8 RAM are sized for control-loop firmware, sensor fusion, or user-interface logic where a 16- or 32-bit core would be overkill and the 8-bit architecture keeps the unit cost low.
I/O and analog peripheral count
With 36 I/O lines in a 44-TQFP (10x10 mm body), this MCU gives you enough pins to handle a keypad matrix, a character LCD in 4-bit mode, and a handful of pushbuttons and LEDs without resorting to a port expander. The 35-channel 10-bit SAR ADC covers a lot of analog inputs — thermistors, potentiometers, current-sense resistors — and the single 8-bit DAC handles one analog output, such as a setpoint voltage or a simple waveform.
LINbus is a common choice for automotive subnets (window lifts, seat controls) and industrial sensor buses, which broadens the application scope beyond simple embedded control.
For a procurement decision, that means the supply channel is standard — no premium for obsolete stock, no risk of a forced redesign mid-production. The base product number is PIC16F18075, so future variants (differing only in temperature or package) share the same core architecture and toolchain.
Programming and toolchain
This MCU uses the standard PIC programming interface. MPLAB X IDE and the MPLAB PICkit or ICD debuggers support the full 8-bit PIC® 16F family — no special adapter or firmware patch needed. The internal oscillator option (External, Internal) means a prototype can run without an external crystal for non-timing-critical applications, saving two pins and a few cents on the BOM. For production programming, Microchip's gang programmers and third-party programmers (e.g., Dataman, Xeltek) handle the 44-TQFP package with the appropriate socket adapter.
