This document introduces the HP LaserJet Pro MFP M236n multifunction printer. This printer offers printing, copying, scanning and faxing capabilities. It also supports automatic double-sided printing.
The EM78P153S is an 8‑bit microprocessor with low‑power, high‑speed CMOS technology that includes a 1024 × 13‑bit One‑Time Programmable ROM. It offers a protection bit, 15 option bits, two bi‑directional I/O ports, a real‑time clock/counter, and several interrupt sources. The manual lists operating voltage, temperature, frequency ranges, power consumption, and built‑in calibrated oscillators.
The document includes a pin‑assignment table, functional block diagram, register descriptions, and AC electrical characteristics. Package options are provided for 14‑pin DIP and SOP versions, along with detailed timing parameters for reset, watchdog, and I/O pins.
