32 MHz core, 7 KB Flash — what fits in this envelope
The Microchip PIC16LF1783-I/SP is an 8-bit PIC MCU from the PIC® XLP™ 16F family, clocked at 32 MHz with 7 KB (4K x 14) program Flash, 512 bytes of RAM, and 256 bytes of EEPROM.
Mixed-signal peripherals and interface set
Eleven 12-bit ADC channels and one 8-bit DAC give this part a genuine analog front-end — useful for sensor conditioning or closed-loop control without an external converter. The peripheral set includes a Programmable Switch Mode Controller (PSMC) for PWM generation, plus Brown-out Reset, Power-on Reset, and a Watchdog Timer for unsupervised operation.
Through-hole package and layout consideration
Supplied in a 28-pin SPDIP (0.300″ body width, 7.62 mm row spacing) — a through-hole footprint that simplifies prototyping and hand-assembly. The 24 available I/O lines are enough for a keypad, a small display, or a dozen sensor inputs, but the pin pitch (2.54 mm) means the board area is larger than an equivalent TSSOP or QFN. Plan for a 2-layer PCB; the SPDIP fan-out is straightforward.
