Product details
Overview
M30879FLBFP#U3 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 10-bit A/D conversion across 26 channels in single-chip mode, and targets industrial motor control and office automation systems.
For engineers reviewing the M30879FLBFP#U3 datasheet, M30879FLBFP#U3 pinout, M30879FLBFP#U3 application, or M30879FLBFP#U3 equivalent, key selection criteria include its 100-pin LQFP (PRQP0100JB-A) package, absence of CAN interfaces, 26-channel ADC capability, integrated 3-phase motor control timers, and support for external bus expansion with 16-Mbyte address space.
Technical Context
The M30879FLBFP#U3 implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit). It integrates dual DMAC units (DMAC and DMACII), five 16-bit Timer A modules with PWM and 2-phase encoder input, and six 16-bit Timer B modules for pulse measurement and period capture.
Its peripheral set includes five UARTs (UART0–UART4), one additional UART5, I²C, IrDA, HDLC, and optional IEBus - all without CAN functionality per M32C/87B specification. Power management includes wait and stop modes achieving 45 μA and 0.8 μA current draw respectively at 3.3 V.

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 native IEBus support | Higher performance for servo loop computation; lacks IEBus required in legacy Japanese office equipment | Select when migrating to modern 32-bit architecture with C++ toolchain support and no IEBus dependency |
| M30879FLAFP | Same M32C/87A family, identical package and pinout, but includes 1-channel CAN 2.0B controller | Enables CAN-based fieldbus communication in motor drives where distributed node messaging is required | Choose if CAN connectivity is needed and board layout must remain unchanged - pin-compatible upgrade path |
Compared with R5F566TEADFP and M30879FLAFP, the M30879FLBFP#U3 provides optimal cost/performance for CAN-free industrial control where IEBus or legacy UART protocols dominate, while maintaining full software compatibility within the M32C/87 family.

FAQ
What is the maximum operating frequency and supply voltage range for the M30879FLBFP#U3?
The M30879FLBFP#U3 operates at up to 32 MHz when VCC1 is 4.2–5.5 V, with minimum instruction execution time of 31.3 ns. At lower voltage, it supports 24 MHz operation with VCC1 = 3.0–5.5 V. VCC2 must be 3.0 V to VCC1. These ratings are specified in the Renesas REJ03B0127-0151 datasheet Rev. 1.51.
Does the M30879FLBFP#U3 include a CAN controller?
No, the M30879FLBFP#U3 belongs to the M32C/87B subgroup, which explicitly excludes CAN functionality. Tables 1.5–1.7 and Note 5 in Figure 1.2 confirm that M32C/87B devices have zero CAN channels - unlike M32C/87 (2 channels) or M32C/87A (1 channel).
How many A/D converter channels does the M30879FLBFP#U3 support, and what is their resolution?
The M30879FLBFP#U3 supports 26 channels of 10-bit A/D conversion in single-chip mode, and 10 channels in memory expansion or microprocessor mode. All channels include sample-and-hold circuitry, as documented in Table 1.4 under "A/D Converter" for the 100-pin package.
What package type and pin count does the M30879FLBFP#U3 use?
The M30879FLBFP#U3 uses a 100-pin plastic QFP package with part code PRQP0100JB-A (JEDEC MS-026AC), 0.65 mm lead pitch, and 14 mm × 20 mm body dimensions. This is confirmed in Table 1.7 and Figure 1.1 of the Renesas datasheet REJ03B0127-0151.
Is on-chip debug supported for the M30879FLBFP#U3, and what capabilities does it provide?
Yes, the M30879FLBFP#U3 supports full on-chip debug including real-time program trace, hardware breakpoints, memory inspection, and in-system flash reprogramming. These features are enabled via the dedicated debug interface and are listed under "Debug functions" in Table 1.4 of the official Renesas documentation.
