Renesas M30875FHBGP#U3

Overview

M30875FHBGP#U3 from Renesas Electronics is a 384 KB flash-based 16-bit MCU in the M32C/87B family, featuring an M32C/80 CPU core, 24 KB RAM, 144-pin LQFP package, CAN 2.0B support disabled (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, 3-phase inverter timing, and dual 8-bit DACs.

For engineers reviewing the M30875FHBGP#U3 datasheet, M30875FHBGP#U3 pinout, M30875FHBGP#U3 application, or M30875FHBGP#U3 equivalent, key selection considerations include its 144-pin PLQP0144KA-A package, absence of CAN modules, 34-channel 10-bit ADC (single-chip mode), on-chip dead-time timer for motor drive, and compatibility with Renesas' M32C development tools and debug infrastructure.

Technical Context

The M30875FHBGP#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 five 16-bit Timer A units (supporting PWM, encoder input, and one-shot modes), six 16-bit Timer B units (pulse width/period measurement), and dedicated 3-phase motor control logic using Timer A1/A2/A4 and Timer B2 - all coordinated by an on-chip dead-time timer to prevent shoot-through in inverter gate drives.

FAQ

What is the maximum operating frequency and supply voltage range for the M30875FHBGP#U3?

The M30875FHBGP#U3 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, achieving a minimum instruction execution time of 31.3 ns. At 24 MHz, it supports a wider VCC1 range of 3.0 V to 5.5 V. VCC2 must be maintained between 3.0 V and VCC1 in all configurations. These specifications are defined in Renesas document REJ03B0127-0151 Rev.1.51.

Does the M30875FHBGP#U3 include CAN interface capability?

No, the M30875FHBGP#U3 belongs to the M32C/87B variant, which explicitly excludes CAN modules per Renesas product numbering and specification tables. While pins like P8_2 (CAN0OUT) and P9_5 (CAN1IN) are physically present on the 144-pin package, their CAN functionality is disabled in silicon and not electrically supported. The M30875FHBGP#U3 retains full UART, I²C, and intelligent I/O capabilities.

How many analog-to-digital converter channels does the M30875FHBGP#U3 support?

The M30875FHBGP#U3 supports 34 channels of 10-bit ADC in single-chip mode, as confirmed in Table 1.1 of the Renesas datasheet REJ03B0127-0151. This includes AN0_0–AN0_7, AN2_0–AN2_7, AN15_0–AN15_7, and AN_0–AN_7. Channel count reduces to 26 in memory expansion or microprocessor modes. All channels include sample-and-hold circuitry for accurate simultaneous sampling.

What debug and programming interfaces are supported by the M30875FHBGP#U3?

The M30875FHBGP#U3 supports on-chip debug via Renesas E8/E8a debuggers and on-board flash reprogramming through the on-chip debug interface. It does not require external JTAG emulators for basic firmware development or field updates. The device also implements ROM code protection and ID code check features to secure intellectual property during production programming.

Is the M30875FHBGP#U3 pin-compatible with other members of the M32C/87 Group?

Yes, the M30875FHBGP#U3 uses the same 144-pin LQFP (PLQP0144KA-A) package and shares identical pin assignments with other 144-pin M32C/87 variants such as M30875FHAGP (M32C/87A) and M30875FLGP (M32C/87). However, functional differences exist - notably CAN pin disablement in M32C/87B - so firmware and schematic design must account for absent peripheral resources despite mechanical compatibility.
