Product details
Overview
M30879FLAFP#UG from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87A family, featuring an M32C/80 CPU core, 512 KB ROM + 4 KB data flash, 31 KB RAM, dual CAN 2.0B channels (M32C/87A variant), and operation up to 32 MHz at 4.2–5.5 V. It integrates UARTs, I²C, timers, 10-bit ADC (26 channels), 8-bit DAC, and intelligent I/O for industrial motor control and communication equipment.
For engineers reviewing the M30879FLAFP#UG datasheet, M30879FLAFP#UG pinout, M30879FLAFP#UG application, or M30879FLAFP#UG equivalent, key selection criteria include its 100-pin QFP package (PRQP0100JB-A), dual-CAN support, 26-channel ADC in single-chip mode, on-chip debug capability, and compatibility with Renesas' M32C development tools and E1/E20 debuggers.
Technical Context
The M30879FLAFP#UG implements the M32C/80 CPU core with 108 basic instructions and supports three operating modes: single-chip, memory expansion, and microprocessor. Its external bus interface provides 16-Mbyte address space, configurable wait states (1–7), four chip selects, and dual-voltage (3 V/5 V) support with switchable bus formats (separate/multiplexed) and data width (8-/16-bit).
It embeds two independent CAN 2.0B modules (16-slot × 1 channel each), five UARTs with IrDA/I²C/GCI modes, a 15-bit watchdog timer, four-channel DMAC with cycle-steal transfer, and dedicated hardware for 3-phase motor control using Timer A and Timer B resources - all synchronized via a PLL frequency synthesizer and four clock sources (main, sub, on-chip oscillator, PLL).

FAQ
What is the maximum operating frequency and supply voltage range for the M30879FLAFP#UG?
The M30879FLAFP#UG operates at up to 32 MHz with VCC1 = 4.2–5.5 V, or 24 MHz with VCC1 = 3.0–5.5 V. VCC2 must be within 3.0 V to VCC1. This dual-voltage flexibility allows interoperability with both 3.3 V and 5 V peripheral logic while maintaining CPU performance headroom. The M30879FLAFP#UG's specification sheet confirms these limits under "Operating Frequency/Supply Voltage" in Table 1.4.
Does the M30879FLAFP#UG support on-chip debugging and in-field firmware updates?
Yes, the M30879FLAFP#UG includes an integrated on-chip debug module compatible with Renesas E1/E20 debuggers and supports on-board flash reprogramming via UART or dedicated debug interface. This enables full source-level debugging, real-time trace, and secure field updates without requiring external programmers. The M30879FLAFP#UG datasheet explicitly lists "On-chip debug and on-board flash reprogram" under Flash Memory features in Table 1.4.
How many analog-to-digital converter (ADC) channels does the M30879FLAFP#UG provide, and what is their resolution?
The M30879FLAFP#UG provides 26 channels of 10-bit ADC in single-chip mode, with sample-and-hold functionality. In memory expansion or microprocessor modes, it supports 10 channels. This ADC configuration is optimized for multi-sensor monitoring in motor drives and power supplies. The M30879FLAFP#UG specification is confirmed in Table 1.4 under "A/D Converter".
What package type and pin count does the M30879FLAFP#UG use, and is it RoHS-compliant?
The M30879FLAFP#UG uses a 100-pin plastic QFP package (PRQP0100JB-A) with 0.65 mm lead pitch and is RoHS-compliant. This package is distinct from the 100-pin LQFP variant (PLQP0100KB-A) used by other M32C/87A members. The M30879FLAFP#UG's package code "FP" is defined in Figure 1.1 and Table 1.6 of the official Renesas documentation.
Does the M30879FLAFP#UG include CAN interface support, and how many channels are implemented?
Yes, the M30879FLAFP#UG belongs to the M32C/87A subgroup and implements one CAN 2.0B module with 16 message slots - not two. Although early documentation ambiguously references "M32C/87: 16 slots × 2 channels", Table 1.6 and Note 5 in the datasheet clarify that M30879FLAFP#UG (suffix "A") has only one CAN channel. The M30879FLAFP#UG's CAN0 pins (P8_2/P8_3, P7_6/P7_7) are functional; CAN1 pins are not bonded in this variant.
