Overview

M30875FHBGP#U3P from Renesas Electronics is a 144-pin LQFP microcontroller in the M32C/87B family, featuring the M32C/80 CPU core, 384 KB flash + 4 KB data flash, 24 KB RAM, dual CAN 2.0B modules (disabled in M32C/87B variant), and 10-bit A/D converter with 34 channels - deployed in industrial motor control and office automation systems requiring deterministic real-time processing.

For engineers reviewing the M30875FHBGP#U3P datasheet, M30875FHBGP#U3P pinout, M30875FHBGP#U3P application, or M30875FHBGP#U3P equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, 32 MHz max operating frequency at 4.2–5.5 V, integrated DMAC with 4 channels, on-chip dead-time timer for 3-phase inverter control, and UART/I²C/IEBus serial interfaces supporting multi-protocol embedded communication.

Technical Context

The M30875FHBGP#U3P implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), enabling efficient execution of complex control algorithms. Its memory architecture supports single-chip, memory expansion, and microprocessor modes with a full 16-Mbyte external address space and configurable bus width (8-/16-bit) and wait states (1–7).

Peripheral integration includes Timer A (5×16-bit) with PWM and 2-phase encoder input, Timer B (6×16-bit) for pulse measurement, intelligent I/O with 16-channel waveform generation, CRC-CCITT calculation circuit, and X/Y converter (16×16-bit). The device lacks CAN functionality per M32C/87B specification but retains all other M32C/87 Group peripherals including dual D/A converters and voltage detection (Vdet3/Vdet4).

FAQ

Does M30875FHBGP#U3P support CAN communication?

No, M30875FHBGP#U3P is an M32C/87B variant and explicitly excludes CAN functionality per Renesas documentation. While CAN-related pins (e.g., P8_2/P8_3) exist on the 144-pin package, they are unconnected internally and cannot be enabled. For CAN support, select M30875FHAGP (M32C/87A, 1 channel) or M30875FLGP (M32C/87, 2 channels). The M30875FHBGP#U3P retains all other M32C/87 peripherals including UART, I²C, and IEBus.

What is the maximum operating frequency and supply voltage for M30875FHBGP#U3P?

M30875FHBGP#U3P operates up to 32 MHz when VCC1 is maintained between 4.2 V and 5.5 V, achieving a minimum instruction execution time of 31.3 ns. At lower voltages (3.0–5.5 V), the maximum frequency is 24 MHz (41.7 ns min instruction time). VCC2 must be set between 3.0 V and VCC1. These ratings are validated per Renesas REJ03B0127-0151 Rev.1.51 specifications.

Which package type does M30875FHBGP#U3P use, and what are its mechanical dimensions?

M30875FHBGP#U3P uses the PLQP0144KA-A package: a 144-pin plastic LQFP with 20 mm × 20 mm body size and 0.5 mm lead pitch. This is confirmed in Table 1.7 and Figure 1.3 of the Renesas M32C/87 Group datasheet REJ03B0127-0151. The package has no exposed thermal pad, and pin 1 location follows standard LQFP marking conventions per Renesas package drawings.

How many A/D converter channels does M30875FHBGP#U3P support, and what resolution do they provide?

M30875FHBGP#U3P supports 34 channels of 10-bit analog-to-digital conversion in single-chip mode, with built-in sample-and-hold circuitry. This count applies specifically to the 144-pin variant; the 100-pin versions offer fewer channels. All 34 channels are accessible via dedicated ANx_y pin names (e.g., AN0_0 through AN0_7, AN15_0 through AN15_7) as documented in the pin assignment tables.

Is on-chip debug supported for M30875FHBGP#U3P, and what tools are compatible?

Yes, M30875FHBGP#U3P fully supports on-chip debug via Renesas E8/E8a emulators and the Renesas Flash Programmer toolchain. Debug features include breakpoint setting, register/memory inspection, and on-board flash reprogramming without removing the device from the target board. This capability is confirmed in Section 1.1.2 and Table 1.2 of the official datasheet REJ03B0127-0151.
