Renesas M3087BFLGP#U3

Overview

M3087BFLGP#U3 from Renesas Electronics is a 144-pin LQFP 32-bit microcontroller in the M32C/87 Group, featuring the M32C/80 CPU core, 1 MB + 4 KB data flash ROM, 48 KB RAM, dual CAN 2.0B modules, and 34-channel 10-bit ADC - deployed in industrial motor control and office automation systems requiring deterministic real-time response.

For engineers reviewing the M3087BFLGP#U3 datasheet, M3087BFLGP#U3 pinout, M3087BFLGP#U3 application, or M3087BFLGP#U3 equivalent, key selection criteria include its 32 MHz operation at 4.2–5.5 V, dual-CAN interface support, 144-pin PLQP0144KA-A package with full peripheral pin mapping, and compatibility with Renesas' on-chip debug and flash reprogramming tools.

Technical Context

The M3087BFLGP#U3 implements a 16-Mbyte external address space with configurable bus timing (1–7 wait states), separate/multiplexed bus format selection, and 8-/16-bit data width switching - enabling flexible memory expansion for embedded control applications. Its dual CAN 2.0B controllers each support 16 message slots and operate independently with dedicated transmit/receive buffers.

It integrates two DMA controllers: DMAC (4 channels, cycle-steal, 43 trigger sources) and DMACII (burst/single transfer, chain/calculation modes), plus five 16-bit Timer A units supporting PWM, encoder input, and 3-phase motor control using A1/A2/A4/B2 - all synchronized to a PLL-based clock system with main/sub/oscillator/PLL sources and programmable dividers (1–16).

FAQ

What is the maximum operating frequency and voltage range for the M3087BFLGP#U3?

The M3087BFLGP#U3 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or at 24 MHz with VCC1 from 3.0 V to 5.5 V. VCC2 must be within 3.0 V to VCC1. This dual-voltage domain supports mixed-signal interfacing while maintaining CPU performance stability across industrial supply variations. The M3087BFLGP#U3 datasheet specifies these limits in Table 1.1 and Table 1.3 under "Operating Frequency/Supply Voltage".

Does the M3087BFLGP#U3 include hardware support for 3-phase motor control?

Yes, the M3087BFLGP#U3 integrates dedicated 3-phase inverter control logic using Timer A1, A2, A4, and Timer B2 with on-chip dead-time insertion - enabling direct generation of six complementary PWM signals for IGBT or MOSFET gate drivers. This hardware acceleration eliminates software timing jitter and simplifies compliance with IEC 60730 safety requirements. The M3087BFLGP#U3 block diagram (Figure 1.2) and Timer section (Table 1.1) confirm this capability.

How many CAN interfaces does the M3087BFLGP#U3 support, and what version of the CAN protocol is implemented?

The M3087BFLGP#U3 supports two independent CAN 2.0B-compliant controllers, each with 16 message slots and full ID filtering. It does not support CAN FD. The CAN0 and CAN1 pins (e.g., P8_2/P8_3 and P9_5/P9_6) are physically separated to prevent coupling, and both channels operate concurrently without CPU intervention. This is explicitly stated in Table 1.2 and confirmed in the Product List (Table 1.5) for the "M32C/87" variant.

What package type and pin count does the M3087BFLGP#U3 use?

The M3087BFLGP#U3 uses a 144-pin LQFP package designated PLQP0144KA-A (20 mm × 20 mm, 0.5 mm pitch), as specified in Table 1.5 and Figure 1.3 of the Renesas documentation. This package provides full access to all peripherals including dual CAN, 34-channel ADC, and intelligent I/O - distinguishing it from 100-pin variants which reduce analog and I/O count. The "GP" suffix in the part number directly encodes this package type.

Is on-chip debug and flash reprogramming supported on the M3087BFLGP#U3?

Yes, the M3087BFLGP#U3 includes full on-chip debug capability and supports on-board flash reprogramming via UART or CAN boot loader - eliminating the need for external debug probes during development or field updates. These features are listed under "Debug functions" in Table 1.2 and Table 1.4, and are integral to the M32C/87 Group's design for rapid firmware iteration and maintenance. The M3087BFLGP#U3 leverages Renesas' standard E8/E8a debug interface.
