Overview

M30879FLAFP#U3 from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87A family, embedding the M32C/80 CPU core with 768 KB ROM + 4 KB data flash, 31 KB RAM, dual CAN 2.0B channels (M32C/87A variant), and 26-channel 10-bit ADC - deployed in industrial motor control and office automation systems requiring deterministic real-time response.

For engineers reviewing the M30879FLAFP#U3 datasheet, M30879FLAFP#U3 pinout, M30879FLAFP#U3 application, or M30879FLAFP#U3 equivalent, this page delivers verified specifications, validated pin functions for the PRQP0100JB-A package, confirmed CAN 2.0B dual-channel operation, and direct alternative part comparisons - all aligned to Renesas' REJ03B0127-0151 Rev.1.51 specification.

Technical Context

The M30879FLAFP#U3 implements the M32C/80 CPU core with 16×16→32-bit multiplier and 16×16+48→48-bit multiply-add instructions, executing at 32 MHz (min. 31.3 ns/instruction) under 4.2–5.5 V supply. It supports single-chip, memory expansion, and microprocessor operating modes with 16-Mbyte external address space and configurable 8-/16-bit bus width.

Its peripheral set includes five 16-bit Timer A units (PWM, encoder input, one-shot), six 16-bit Timer B units (pulse width/period measurement), dual CAN 2.0B controllers (16-slot × 1 channel per controller), seven UARTs (including IrDA and IEBus support), and two 8-bit DACs - all synchronized via four independent clock sources (main, sub, on-chip oscillator, PLL).
