Product details
Overview
M30879FLAFP#U5 from Renesas Electronics is a 100-pin LQFP microcontroller in the M32C/87A family, embedding the M32C/80 CPU core with 1-channel CAN 2.0B support, 10-bit A/D converter (26 channels in single-chip mode), 8-bit D/A converter (2 channels), and 5 UART interfaces. It operates at up to 32 MHz (VCC1 = 4.2–5.5 V) and targets industrial motor control and office automation systems.
For engineers reviewing the M30879FLAFP#U5 datasheet, M30879FLAFP#U5 pinout, M30879FLAFP#U5 application, or M30879FLAFP#U5 equivalent, key selection criteria include its 100-pin QFP package (PRQP0100JB-A), single CAN channel configuration, 26-channel ADC capability in single-chip mode, on-chip PLL and DMAC, and support for IEBus (optional) and IrDA modes.
Technical Context
The M30879FLAFP#U5 implements the M32C/80 16-bit CPU core with 108 basic instructions and multiplier support (16×16→32-bit, 16×16+48→48-bit). Its memory architecture includes flash ROM (capacity not specified for this variant but consistent with M32C/87A family), 48 KB RAM, and data flash (4 KB optional), all accessible within a 16-Mbyte address space.
Peripheral integration includes dual DMAC units (DMAC and DMACII), five 16-bit Timer A modules with PWM and encoder input, six 16-bit Timer B modules for pulse measurement, three-phase motor control logic using TA1–TA4 and TB2, and intelligent I/O supporting HDLC, IEBus, and clock-synchronous/asynchronous serial protocols.

FAQ
What is the package type and pin count of the M30879FLAFP#U5?
The M30879FLAFP#U5 uses a 100-pin plastic QFP package (PRQP0100JB-A) with 0.65 mm lead pitch and 14 mm × 14 mm body size. This package is distinct from the 144-pin LQFP variants in the M32C/87 family and is optimized for compact industrial control boards where board space is constrained.
Does the M30879FLAFP#U5 support CAN communication, and how many channels does it have?
Yes, the M30879FLAFP#U5 supports CAN 2.0B communication as part of the M32C/87A variant, featuring one fully integrated CAN channel with 16 message slots. It does not support dual CAN like the M32C/87 variant, and CAN functionality is disabled in M32C/87B devices.
What are the ADC and DAC specifications of the M30879FLAFP#U5?
The M30879FLAFP#U5 integrates a 10-bit successive-approximation ADC with up to 26 input channels in single-chip mode and two 8-bit voltage-output DAC channels. The ADC includes sample-and-hold circuitry and supports programmable trigger sources including timers and external events.
Can the M30879FLAFP#U5 operate in low-power modes, and what are the typical current draws?
Yes, the M30879FLAFP#U5 supports wait mode (≈45 μA at 1 MHz, VCC = 3.3 V) and stop mode (0.8 μA at VCC = 3.3 V). These modes are controlled via software and preserve RAM contents and register states, enabling fast wake-up for event-driven industrial sensing applications.
Is on-chip debug supported for the M30879FLAFP#U5, and what interface is used?
Yes, the M30879FLAFP#U5 supports full on-chip debug via JTAG interface, enabling real-time breakpoints, register inspection, and flash memory programming without requiring external debug probes beyond standard JTAG adapters compatible with Renesas E1/E20 emulators.
