Product details

Overview

M301N2F8FP#U3 from Renesas Electronics is a 16-bit flash-based microcontroller in the M16C/1N group, featuring an on-chip M16C/60 series CPU core, 64 KB Flash ROM, 3 KB RAM, and integrated CAN 2.0B controller. It operates from 4.2 V to 5.5 V at up to 16 MHz (62.5 ns instruction cycle), and targets automotive and industrial control systems requiring real-time I/O, analog conversion, and robust communication.

For engineers reviewing the M301N2F8FP#U3 datasheet, M301N2F8FP#U3 pinout, M301N2F8FP#U3 application, or M301N2F8FP#U3 equivalent, this page delivers verified technical context, exact package mapping (48-pin LQFP, package code 48P6Q-A), confirmed peripheral integration (12-channel 10-bit A/D, dual UART, 8-bit D/A, five timers), and two validated alternative parts for functional migration paths.

Technical Context

The M301N2F8FP#U3 implements a silicon-gate CMOS 16-bit CPU with 91 basic instructions and a one-megabyte linear address space. Its memory architecture includes fixed interrupt vectors at FFFDC–FFFFF₁₆, user-configurable interrupt table base via INTB register, and special-page vector table at FFE00–FFFDB₁₆ enabling 2-byte subroutine calls.

Peripheral integration is tightly coupled to the CPU via SFRs mapped in the 00000–003FF₁₆ region. The CAN 2.0B controller supports software-selectable I/O on P02/P03 or P50/P51, while the A/D converter offers expandable 12-to-14 channel operation with programmable resolution and reference voltage input (VREF).
