Product details
Overview
M30879FKGP#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, 768 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B modules (16-slot × 2 channels), and operation up to 32 MHz at 4.2–5.5 V - deployed in industrial motor control and office automation systems.
For engineers reviewing the M30879FKGP#U3 datasheet, M30879FKGP#U3 pinout, M30879FKGP#U3 application, or M30879FKGP#U3 equivalent, key selection considerations include its dual-CAN interface, 100-pin LQFP package (PLQP0100KB-A), 10-bit 26-channel ADC in single-chip mode, integrated 3-phase motor control timers, and on-chip debug support for flash reprogramming.
Technical Context
The M30879FKGP#U3 implements the M32C/80 CPU core with 108 basic instructions and supports single-chip, memory expansion, and microprocessor operating modes. It integrates two independent CAN 2.0B controllers (16 message slots per channel), a 16-Mbyte external address space with configurable wait states, and PLL-based clock synthesis with main/sub/oscillator/PLL sources.
Its peripheral set includes five 16-bit Timer A units (supporting PWM, encoder input, and 3-phase inverter control), six 16-bit Timer B units (for pulse width/period measurement), four-channel DMAC with cycle-steal transfer, and UART0–UART4 with I²C, IrDA, and optional IEBus - all accessible via dedicated intelligent I/O pins with input capture and output compare functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | M32C/80 core with 16×16→32-bit multiplier and 16×16+48→48-bit multiply-add; enables efficient real-time math for motor control algorithms. |
| Flash Memory | 768 KB program flash + 4 KB data flash; supports in-system programming and ROM code protection for secure firmware updates. |
| CAN Interface | Dual CAN 2.0B channels (16 slots each); provides redundant or multi-bus automotive/industrial networking without external transceivers. |
| ADC | 10-bit resolution × 26 channels (single-chip mode); sufficient for simultaneous sampling of motor phase currents, temperature, and voltage feedback. |
| Operating Frequency | 32 MHz max (VCC1 = 4.2–5.5 V); delivers 31.3 ns minimum instruction execution time for deterministic real-time response. |
| Package | 100-pin LQFP (PLQP0100KB-A); RoHS-compliant surface-mount package with 0.5 mm pitch, suitable for high-density industrial PCBs. |
| Power Modes | Wait mode (45 μA @ 1 MHz) and stop mode (0.8 μA); enables ultra-low-power standby in battery-backed or energy-sensitive applications. |
Pinout & Package
Package: 100-pin LQFP (PLQP0100KB-A), 14 × 14 mm body, 0.5 mm lead pitch, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P9_6 | CAN1OUT / TXD4 / SDA4 | Dual-function pin: primary CAN1 transmit output; also serves as UART4 TX and I²C data line - requires external CAN transceiver for bus coupling. |
| P9_5 | CAN1IN / CAN1WU / CLK4 | CAN1 receive input with wake-up capability; shares pin with UART4 clock - enables low-power CAN bus monitoring without full MCU wake. |
| P8_3 / P8_2 | CAN0IN / CAN0OUT | Dedicated CAN0 channel pins; support full-duplex communication on separate CAN bus segment - no software multiplexing required. |
| P10_0–P10_7 | AN_0–AN_7 / KI0–KI3 / RTP1_0–RTP3_3 | Eight analog input channels with keypad interrupt and resistor ladder touch support; enables direct front-panel HMI integration without external ADC or GPIO expanders. |
| P5_0–P5_4 | WRL / WRH / RD / HLDA / HOLD | External bus control signals; allow connection to external SRAM, NOR flash, or FPGA peripherals using 8-/16-bit multiplexed or non-multiplexed bus format. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 3-phase motor control | Uses Timer A1/A2/A4 and Timer B2 to generate complementary PWM with programmable dead time - eliminates need for external gate driver logic. |
| On-chip debug & flash reprogram | Supports real-time debugging and field firmware updates via on-chip debug interface - reduces production test time and enables post-deployment feature upgrades. |
| Dual independent CAN 2.0B controllers | Each with 16 message slots and dedicated FIFOs; allows concurrent communication on two isolated CAN networks (e.g., control bus + diagnostics bus). |
| Intelligent I/O with encoder input | Two 16-bit timers provide 8-channel input capture and 10-channel output compare; directly interfaces with quadrature encoders for position/speed feedback. |
| CRC-CCITT calculation hardware | Accelerates frame integrity checking in CAN, UART, and custom protocols - offloads CPU and ensures deterministic timing for safety-critical messaging. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP | 32-bit RX66T core, 1 MB flash, single CAN channel, 12-bit 24-channel ADC, operates up to 160 MHz | Higher performance for complex motion control but lacks second CAN channel; requires external CAN transceiver for dual-bus designs | Select when migrating to 32-bit architecture with higher computational throughput, accepting trade-off in dual-CAN capability |
| M30879FLGP#U3 | Same M32C/87A family, 100-pin LQFP, 1 MB + 4 KB flash, 48 KB RAM, single CAN channel (16 slots) | Reduced flash/RAM and single CAN - suitable for cost-sensitive applications where dual-network redundancy is unnecessary | Select when firmware size exceeds 768 KB or dual CAN is not required, leveraging identical pinout and peripheral register map |
Compared with R5F566TEADFP and M30879FLGP#U3, the M30879FKGP#U3 uniquely balances legacy 16-bit code compatibility, dual-CAN networking, and 768 KB flash density - making it optimal for incremental upgrades of existing M32C-based industrial controllers requiring bus redundancy without architectural overhaul.

FAQ
What is the maximum operating frequency and supply voltage range for the M30879FKGP#U3?
The M30879FKGP#U3 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. These ranges are defined in the Renesas REJ03B0127-0151 datasheet Rev.1.51 and validated for continuous operation under industrial ambient conditions (–20°C to +85°C).
Does the M30879FKGP#U3 support dual CAN 2.0B interfaces, and how are they implemented?
Yes, the M30879FKGP#U3 supports two independent CAN 2.0B controllers (CAN0 and CAN1), each with 16 message slots and dedicated registers. CAN0 uses pins P8_2/P8_3; CAN1 uses P9_5/P9_6. Both channels operate concurrently without shared resources - confirmed in Table 1.2 and Figure 1.2 of the M32C/87 Group datasheet.
What package type and pin count does the M30879FKGP#U3 use?
The M30879FKGP#U3 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), as specified in Table 1.6 and Figure 1.4 of the Renesas REJ03B0127-0151 datasheet. This matches the M32C/87A variant footprint and is distinct from the 144-pin variant used by M32C/87.
How much flash and RAM memory does the M30879FKGP#U3 include?
The M30879FKGP#U3 integrates 768 KB of on-chip flash memory plus an additional 4 KB of data flash, and 31 KB of RAM. These values are explicitly listed in Table 1.6 of the Renesas M32C/87 Group datasheet (REJ03B0127-0151 Rev.1.51) under the M32C/87A product line.
Is on-chip debug functionality supported on the M30879FKGP#U3?
Yes, the M30879FKGP#U3 supports full on-chip debug (OCD) including breakpoint setting, real-time variable inspection, and flash reprogramming via the standard Renesas E1/E20 debugger interface - documented in Section 1.1.2 "Debug functions" and Table 1.2 of the official datasheet.
