The Microchip PIC16F15256T-I/STX is an 8-bit PIC MCU with 28 KB Flash program memory and 2 KB RAM, running at a 32 MHz core speed.
At 32 MHz the PIC16F15256 executes most single-cycle instructions in 125 ns. That is fast enough to bit-bang a 1 MHz SPI bus, update a PWM period every 8 µs, or poll a 10-bit ADC conversion in under 2 µs. The flash wait-state logic is handled internally, so no configuration tweak is needed when switching from the internal oscillator to the PLL — the core just runs. If your loop has tight timing on I²C or UART framing, budget for the 8-bit data path: a 16-bit multiply takes several cycles, so math-heavy routines may want a 16-bit sibling like the PIC24FV16KA304.
The exposed pad is electrically connected to VSS, so the same via pattern serves as ground plane stitching. Surface-mount assembly follows standard QFN reflow profiles;.
Microchip lists the PIC16F15256T-I/STX as Active (current product).
