Product details
Overview
M30878FJAGP#U3 from Renesas Electronics is a 144-pin LQFP flash-based 16-bit MCU in the M32C/87A family, embedding the M32C/80 CPU core with 512 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B channels (1 active), and 34-channel 10-bit ADC - deployed in industrial motor control and office automation systems requiring deterministic real-time response.
For engineers reviewing the M30878FJAGP#U3 datasheet, M30878FJAGP#U3 pinout, M30878FJAGP#U3 application, or M30878FJAGP#U3 equivalent, key selection criteria include its 32 MHz operation at 4.2–5.5 V, integrated 3-phase inverter timing logic, on-chip debug support, and 144-pin PLQP0144KA-A package with CAN0/CAN1 pin assignment.
Technical Context
The M30878FJAGP#U3 implements the M32C/80 CPU core with 108 basic instructions and 16×16→32-bit multiply-add capability, supporting single-chip, memory expansion, and microprocessor operating modes. Its external bus interface provides 16-Mbyte address space with configurable 1–7 wait states and 4 chip selects.
It integrates two independent DMAC units (DMAC and DMACII), 5×16-bit Timer A modules with PWM and 2-phase encoder input, and a dedicated 3-phase motor control circuit using Timer A1/A2/A4 and Timer B2 - all synchronized to a PLL-based clock system with main/sub/oscillator/PLL sources and programmable frequency division.

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, 120 MHz, 512 KB flash, no CAN, 24-channel ADC | Higher performance but lacks CAN; suited for pure motor control without networked diagnostics | Select when migrating to 32-bit architecture with emphasis on computational throughput over fieldbus compatibility |
| MB9BF516RPMC | 32-bit FM4 core, 144 MHz, 512 KB flash, 2× CAN, 24-channel ADC | Same CAN count but higher clock speed and larger address space; different peripheral mapping | Choose for new designs needing CAN redundancy and faster interrupt response, accepting toolchain migration effort |
Compared with R5F566TEADFP and MB9BF516RPMC, the M30878FJAGP#U3 offers deterministic 16-bit real-time behavior, mature tooling, and direct CAN 2.0B compliance - making it optimal for cost-sensitive, field-proven industrial nodes where software stability outweighs raw MIPS.

FAQ
What is the maximum operating frequency and supply voltage range for the M30878FJAGP#U3?
The M30878FJAGP#U3 operates at up to 32 MHz with VCC1 = 4.2 V to 5.5 V, or 24 MHz with VCC1 = 3.0 V to 5.5 V. VCC2 must be between 3.0 V and VCC1. These ranges are defined in Table 1.1 and Table 1.3 of the REJ03B0127-0151 datasheet, and the M30878FJAGP#U3 must not be operated outside these limits to ensure functional reliability.
Does the M30878FJAGP#U3 support both CAN 2.0A and CAN 2.0B protocols?
Yes, the M30878FJAGP#U3 supports CAN 2.0B specification exclusively, as confirmed in Table 1.2 and Table 1.4. It does not implement CAN 2.0A frame format. The M30878FJAGP#U3 implements full 29-bit extended identifier support and message object arbitration per ISO 11898-1, with 16 message slots allocated to its single active CAN channel (CAN0).
How many ADC channels are available on the M30878FJAGP#U3 and what is their resolution?
The M30878FJAGP#U3 provides 34 channels of 10-bit successive-approximation ADC in single-chip mode, as specified in Table 1.1. This includes sample-and-hold functionality and supports simultaneous sampling triggers from timer events. In memory expansion or microprocessor modes, only 18 channels remain accessible - a detail confirmed in the M30878FJAGP#U3 product listing and block diagram.
What debug interface does the M30878FJAGP#U3 support and is on-chip flash reprogramming possible?
The M30878FJAGP#U3 supports on-chip debug via JTAG interface and enables full flash reprogramming in-system using the built-in serial programming function. This capability is documented in Table 1.2 under "Debug functions" and verified in Section 1.1.2 of the REJ03B0127-0151 datasheet - allowing firmware updates without removing the M30878FJAGP#U3 from the target board.
Is the M30878FJAGP#U3 pin-compatible with other members of the M32C/87 Group such as M30879FLGP?
No - the M30878FJAGP#U3 uses the 144-pin PLQP0144KA-A package, while M30879FLGP is offered in 100-pin PRQP0100JB-A and PLQP0100KB-A packages. Pin count, pitch, and signal mapping differ fundamentally; therefore, the M30878FJAGP#U3 is not pin-compatible with any 100-pin variant. Direct replacement requires PCB redesign.
