M30879FLGP#U3 from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87 Group, featuring the M32C/80 CPU core, 512 KB ROM + 4 KB data flash, 31 KB RAM, dual CAN 2.0B modules (16-slot × 2 channels), and 26-channel 10-bit ADC - deployed in industrial motor control and office automation systems requiring real-time I/O and deterministic communication.
For engineers reviewing the M30879FLGP#U3 datasheet, M30879FLGP#U3 pinout, M30879FLGP#U3 application, or M30879FLGP#U3 equivalent, key selection criteria include its 100-pin PLQP0100KB-A package, dual-CAN capability, 32 MHz operation at 4.2–5.5 V, integrated 3-phase motor control timers, and on-chip debug support for firmware development and field reprogramming.
Technical Context
The M30879FLGP#U3 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), supporting single-chip, memory expansion, and microprocessor operating modes. Its external bus interface provides 16-Mbyte address space with 1–7 wait states, 4 chip selects, and switchable 8-/16-bit data width.
It integrates two independent CAN 2.0B controllers (16-slot × 2 channels), five UARTs (including IrDA and IEBus optional support), six 16-bit timers (Timer A/B), and intelligent I/O with input capture (8 channels) and output compare (10 channels) - all synchronized to a flexible clock system with main/sub oscillators, PLL, and programmable frequency dividers.

How many analog input channels does the M30879FLGP#U3 have, and what is their resolution?
In single-chip mode, the M30879FLGP#U3 provides 26 channels of 10-bit analog-to-digital conversion with built-in sample-and-hold. This configuration applies specifically to the 100-pin LQFP package (PLQP0100KB-A). Channel mapping includes P0_0–P0_7, P10_0–P10_7, and P9_5/P9_6 (ANEX0/ANEX1), all accessible without external multiplexing for the M30879FLGP#U3.
Is the M30879FLGP#U3 pin-compatible with other members of the M32C/87 Group?
Yes, the M30879FLGP#U3 shares identical pinout and electrical characteristics with other 100-pin LQFP variants in the M32C/87 Group, including M30876FJGP (M32C/87A) and M30873FHGP (M32C/87).
