Microchip PIC18F2450/4450 28/40/44-Pin USB Microcontroller Datasheet
The PIC18F2450 and PIC18F4450 are high‑performance 12 MIPS USB microcontrollers offered in 28‑, 40‑ and 44‑pin packages. They provide USB 2.0 compliance with Low‑Speed (1.5 Mb/s) and Full‑Speed (12 Mb/s) operation, up to 32 endpoints, and a 256‑byte dual‑access RAM dedicated to USB functions. The devices include a wide range of peripherals such as multiple timers, a 10‑bit ADC, high‑current I/O, and an 8×8 hardware multiplier.
The datasheet covers device overview, oscillator options, power‑managed modes, memory organization, flash program memory, peripheral modules, USB features, electrical characteristics, packaging information, and migration guides. Pin diagrams for all package types and detailed specifications for voltage, current, and timing are provided.
