Product details
Overview
M30876FJBGP#U3 from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87B family, featuring the M32C/80 CPU core, 512 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B modules (disabled in M32C/87B variant), and operation up to 32 MHz at 4.2–5.5 V. It targets industrial motor control and embedded automation requiring integrated PWM, 10-bit ADC (26 channels), and intelligent I/O.
For engineers reviewing the M30876FJBGP#U3 datasheet, M30876FJBGP#U3 pinout, M30876FJBGP#U3 application, or M30876FJBGP#U3 equivalent, key selection criteria include its 100-pin PLQP0100KB-A package, absence of CAN functionality (M32C/87B variant), 16-bit timer A/B resources for 3-phase motor control, on-chip debug support, and -20°C to +85°C operating range.
Technical Context
The M30876FJBGP#U3 implements the M32C/80 CPU core with 108 basic instructions and supports single-chip, memory expansion, and microprocessor operating modes. Its clock system integrates main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer with selectable division ratios (1–16) and oscillation stop detection.
Peripheral integration includes DMAC (4 channels, cycle-steal method), DMACII (burst/single transfer, chain/calculation functions), 16-bit Timer A ×5 and Timer B ×6, 3-phase inverter control logic using TA1/TA2/TA4/TB2, and an on-chip dead-time timer - all configured for deterministic real-time motor and power control.

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; enhanced FPU and hardware accelerator for motor control | Higher computational throughput for complex FOC; requires PCB redesign due to 100-pin LQFP → 144-pin LQFP migration | Select when upgrading from M32C legacy codebase to modern motor control libraries and require >100 MHz loop performance |
| M30876FJAGP | Same M32C/87A family, 512 KB flash, 31 KB RAM, but includes 1-channel CAN 2.0B module | Enables CAN-based distributed control in multi-node systems; identical pinout and software compatibility | Choose if CAN bus connectivity is required and board layout allows retention of same footprint |
Compared with R5F566TEADFP and M30876FJAGP, the M30876FJBGP#U3 offers lowest-cost entry into Renesas' M32C ecosystem with full peripheral compatibility but excludes CAN - making it optimal for cost-sensitive, self-contained motor control where CAN is unnecessary.

FAQ
What is the CAN capability of the M30876FJBGP#U3?
The M30876FJBGP#U3 belongs to the M32C/87B variant, which has no CAN modules enabled per Renesas documentation (Table 1.7 and note 5). All CAN-related pins (CAN0IN, CAN0OUT, CAN1IN, CAN1OUT) are functionally disabled and must be treated as general-purpose I/O or left unconnected. This distinguishes it from M32C/87 (dual CAN) and M32C/87A (single CAN).
Which package type does M30876FJBGP#U3 use?
M30876FJBGP#U3 uses the 100-pin LQFP package with code PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch), as confirmed in Table 1.7 of the Renesas datasheet REJ03B0127-0151. This matches the pin assignment diagrams for the 100-pin variant and differs from the 144-pin PLQP0144KA-A used by higher-pin-count M32C/87 models.
Does M30876FJBGP#U3 support on-chip debug and flash reprogramming?
Yes, M30876FJBGP#U3 supports full on-chip debug via the standard Renesas E8/E8a emulator interface and in-system flash reprogramming. These capabilities are explicitly listed in the "Flash Memory" row of Table 1.4 and are enabled by its flash memory configuration (F-series part number suffix), allowing firmware updates without removing the device from the board.
What is the maximum ADC channel count supported by M30876FJBGP#U3?
M30876FJBGP#U3 supports 26 channels of 10-bit analog-to-digital conversion in single-chip mode, as specified in Table 1.4. This is lower than the 34-channel capability of the 144-pin variants due to pin count limitations, but includes sample-and-hold functionality essential for accurate multi-channel sampling in motor current sensing.
What operating voltage ranges are valid for M30876FJBGP#U3 at 32 MHz?
At 32 MHz operation, M30876FJBGP#U3 requires VCC1 = 4.2 V to 5.5 V and VCC2 = 3.0 V to VCC1, as defined in Tables 1.2 and 1.4. Operation outside this range - including at 3.3 V supply - is not permitted for 32 MHz mode; the device must be operated at 24 MHz (VCC1 = 3.0–5.5 V) for 3.3 V systems.
