Product details

The Microchip PIC18F46K22-I/MV is an 8-bit MCU from the PIC® XLP™ 18K family, clocked at up to 64 MHz and built around the PIC core.

35 I/O, 30-channel ADC, and serial connectivity

With 35 I/O lines, this MCU can handle a mix of digital inputs, PWM outputs, and serial buses. The 30-channel 10-bit ADC covers analog sensing — temperature, pressure, current — without an external converter. Peripherals such as Brown-out Detect/Reset, HLVD, POR, PWM, and WDT are integrated, reducing external supervisor IC count.

40-UQFN (5x5) — footprint and thermal note

Housed in a 40-pin UQFN with exposed pad (5x5 mm body), the package suits space-constrained PCBs. Surface-mount only; no through-hole variant is offered.

There is no last-time-buy or obsolescence pressure for current designs. ROHS3 compliant.

Frequently asked questions

What is the replacement for PIC18F46K22-I/MV?

There is no official replacement — the part is still active. For a lower-power or smaller-footprint alternative within the same 8-bit PIC family, the PIC16LF1559-I/SS (32 MHz, 17 I/O, 1.8 V min) is a functional peer but with fewer I/O and lower clock speed.

How many I/O pins does PIC18F46K22-I/MV have?

35 I/O lines are available on this 40-pin package.
