Product details
Overview
M30879FLBFP#U5 from Renesas Electronics is a 100-pin LQFP microcontroller in the M32C/87B group, featuring the M32C/80 CPU core, 512 KB flash ROM + 4 KB data flash, 31 KB RAM, and no CAN module. It operates at up to 32 MHz (VCC1 = 4.2–5.5 V), supports 26-channel 10-bit ADC in single-chip mode, dual 8-bit DACs, and is used in office equipment and industrial control systems requiring deterministic real-time processing.
For engineers reviewing the M30879FLBFP#U5 datasheet, M30879FLBFP#U5 pinout, M30879FLBFP#U5 application, or M30879FLBFP#U5 equivalent, key selection considerations include its 100-pin LQFP (PRQP0100JB-A) package, absence of CAN interface, 26-channel ADC configuration, support for I²C/UART/IEBus, and compatibility with Renesas' on-chip debug and flash reprogramming tools.
Technical Context
The M30879FLBFP#U5 implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit). Its memory architecture includes unified 16-Mbyte address space, external bus interface with 4 chip selects and configurable wait states, and dual voltage domains (VCC1 = 4.2–5.5 V, VCC2 = 3.0–VCC1).
Peripheral integration includes five 16-bit Timer A units (supporting PWM, encoder input, and 3-phase motor control), six 16-bit Timer B units (for pulse width/period measurement), DMAC with 4 channels and DMACII with burst transfer capability, and intelligent I/O with 10 waveform generation channels - all operating under single-chip mode with full on-chip oscillator and PLL clock synthesis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP | 32-bit RX66T core, 128 KB RAM, 1 MB flash, integrated FPU, no IEBus, supports CAN FD | Targeted at higher-performance motor control with vector math acceleration; lacks IEBus legacy support | Select when migrating to modern 32-bit platform with enhanced computational throughput and safety features (IEC 61508 SIL2-ready) |
| M30879FLAFP | Same M32C/87A family, identical package and pinout, but includes 1-channel CAN 2.0B module | Enables CAN-based fieldbus communication in industrial networks where M30879FLBFP#U5 lacks native bus interface | Choose if CAN connectivity is required and board layout allows same footprint; software migration path is minimal due to shared peripheral register map |
Compared with R5F566TEADFP and M30879FLAFP, the M30879FLBFP#U5 offers legacy IEBus compatibility and lower power in stop mode (0.8 μA), but trades off CAN capability and 32-bit processing - making it optimal for cost-sensitive, non-networked embedded control where proven M32C toolchain and qualification are critical.

FAQ
What is the maximum operating frequency of the M30879FLBFP#U5 and at what supply voltage?
The M30879FLBFP#U5 achieves a maximum operating frequency of 32 MHz when VCC1 is maintained between 4.2 V and 5.5 V. At this speed, the minimum instruction execution time is 31.3 ns. When operated at 24 MHz, the device supports a wider VCC1 range of 3.0 V to 5.5 V. The M30879FLBFP#U5 uses separate VCC1 (core/IO) and VCC2 (internal logic) supplies, both referenced to the same ground plane.
Does the M30879FLBFP#U5 include a CAN interface, and how does it differ from other M32C/87 variants?
No, the M30879FLBFP#U5 belongs to the M32C/87B subgroup and contains no CAN module. This distinguishes it from M32C/87 (dual CAN) and M32C/87A (single CAN). Pin functions related to CAN (e.g., CAN0IN, CAN0OUT, CAN1IN, CAN1OUT) are physically present on the 100-pin QFP package but are functionally disabled and reserved in the M30879FLBFP#U5 silicon.
How many analog-to-digital converter channels does the M30879FLBFP#U5 support, and under what conditions?
The M30879FLBFP#U5 supports 26 channels of 10-bit analog-to-digital conversion when configured in single-chip mode. In memory expansion or microprocessor modes, the ADC channel count reduces to 10. All channels include sample-and-hold circuitry, and analog inputs are mapped to dedicated pins including P10_0–P10_7 and P2_0–P2_7, with programmable trigger sources including timers and external events.
What debug and programming capabilities are supported by the M30879FLBFP#U5?
The M30879FLBFP#U5 supports on-chip debug via Renesas' E1/E20 emulators using the single-wire debug interface, enabling full breakpoint, watchpoint, and memory inspection without halting real-time peripherals. Flash programming is supported in-system using the on-board bootloader and standard Renesas Flash Development Toolkit, with security features including ROM code protect and ID code check to prevent unauthorized firmware access.
What is the package type and pin count of the M30879FLBFP#U5, and is it RoHS compliant?
The M30879FLBFP#U5 is housed in a 100-pin plastic QFP package with JEDEC designation PRQP0100JB-A (14 mm × 14 mm, 0.65 mm pitch). It complies with the EU RoHS Directive, containing no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE). Full environmental compliance documentation is available from Renesas Electronics upon request.
