Renesas M30875FHBGP#U5

Overview

M30875FHBGP#U5 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 34-channel 10-bit ADC - deployed in industrial motor control and office automation systems requiring deterministic real-time response.

For engineers reviewing the M30875FHBGP#U5 datasheet, M30875FHBGP#U5 pinout, M30875FHBGP#U5 application, or M30875FHBGP#U5 equivalent, key selection considerations include its 144-pin PLQP0144KA-A package, 32 MHz operation at 4.2–5.5 V, integrated 3-phase inverter control timers, on-chip debug support, and absence of CAN functionality per M32C/87B specification.

Technical Context

The M30875FHBGP#U5 implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit), supporting single-chip, memory expansion, and microprocessor operating modes. Its external bus interface provides 16-Mbyte address space with configurable wait states and 4 chip select outputs.

It integrates dual DMAC units (DMAC and DMACII), five 16-bit Timer A channels for PWM and encoder input, six 16-bit Timer B channels for pulse measurement, and dedicated 3-phase motor control logic using Timer A1/A2/A4 and Timer B2 - all synchronized via on-chip dead-time timer and clock generation circuits including PLL, main/sub clocks, and on-chip oscillator.

FAQ

What is the maximum operating frequency and supply voltage range for M30875FHBGP#U5?

M30875FHBGP#U5 operates up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or up to 24 MHz with VCC1 between 3.0 V and 5.5 V. VCC2 must be within 3.0 V to VCC1. These ranges are defined in the official Renesas REJ03B0127-0151 datasheet Rev.1.51, and operation outside these limits may cause functional failure or reduced reliability.

Does M30875FHBGP#U5 include CAN bus functionality?

No, M30875FHBGP#U5 belongs to the M32C/87B variant, which explicitly excludes CAN modules per Table 1.7 and Note 5 in the datasheet. While pin names like CAN0IN/CAN0OUT appear in the 144-pin assignment (e.g., P8_2/P8_3), these signals are unconnected internally and must not be used for CAN communication in M30875FHBGP#U5.

What package type and dimensions does M30875FHBGP#U5 use?

M30875FHBGP#U5 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 mm × 20 mm body size, 0.5 mm lead pitch, and standard JEDEC footprint. This matches the 144P6Q-A designation in Renesas' product numbering system and is confirmed in Tables 1.5–1.7 and Figure 1.3 of REJ03B0127-0151.

How many ADC channels does M30875FHBGP#U5 support, and what is their resolution?

M30875FHBGP#U5 supports 34 channels of 10-bit analog-to-digital conversion in single-chip mode, as specified in Table 1.1 and confirmed by the 144-pin package note "34 channels are available in the 144-pin package." It includes sample-and-hold circuitry essential for accurate multi-channel motor current sensing.

Is on-chip debug supported for M30875FHBGP#U5, and what capabilities does it provide?

Yes, M30875FHBGP#U5 includes full on-chip debug support per Section 1.1.2 and Table 1.2. This enables real-time program execution control, register and memory inspection, breakpoint setting, and in-system flash reprogramming - critical for validating motor control algorithms and reducing development cycle time.
