Renesas M3087BFLAGP#U5

Overview

M3087BFLAGP#U5 from Renesas Electronics is a 144-pin LQFP flash-based 16-bit MCU in the M32C/87 Group, featuring the M32C/80 CPU core, 1 MB + 4 KB data flash, 48 KB RAM, CAN 2.0B support (2-channel), and operation up to 32 MHz at 4.2–5.5 V. It targets industrial motor control, office automation, and communication equipment requiring integrated timers, ADC, and serial interfaces.

For engineers reviewing the M3087BFLAGP#U5 datasheet, M3087BFLAGP#U5 pinout, M3087BFLAGP#U5 application, or M3087BFLAGP#U5 equivalent, key selection considerations include its dual-CAN capability, 34-channel 10-bit ADC in single-chip mode, on-chip dead-time timer for 3-phase inverter control, and 144-pin PLQP0144KA-A package with full peripheral pin mapping.

Technical Context

The M3087BFLAGP#U5 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit, 16×16+48→48-bit). It supports three operating modes - single-chip, memory expansion, and microprocessor - and integrates dual independent CAN 2.0B controllers with 16-slot message buffers per channel.

Its timing subsystem includes five 16-bit Timer A units (supporting PWM, encoder input, and 3-phase motor control) and six 16-bit Timer B units (for pulse width/period measurement), plus dedicated on-chip dead-time generation. The device uses four clock sources: main crystal, sub-crystal, on-chip oscillator, and PLL frequency synthesizer with selectable division ratios (1–16).

FAQ

What is the maximum clock frequency supported by the M3087BFLAGP#U5?

The M3087BFLAGP#U5 supports a maximum CPU clock frequency of 32 MHz when operated at VCC1 = 4.2–5.5 V. At this frequency, the minimum instruction execution time is 31.3 ns. Operation at 24 MHz is supported down to VCC1 = 3.0 V, enabling flexible power/performance trade-offs in battery-powered or low-voltage industrial systems. The M3087BFLAGP#U5 achieves this via its integrated PLL frequency synthesizer and selectable clock dividers.

Does the M3087BFLAGP#U5 include CAN functionality, and how many channels are implemented?

Yes, the M3087BFLAGP#U5 includes two fully independent CAN 2.0B-compliant controllers - one for CAN0 and one for CAN1 - each with 16 message slots. This dual-CAN capability is confirmed in Table 1.1 and Figure 1.2 of the official Renesas documentation. Unlike the M32C/87A (1 channel) or M32C/87B (no CAN), the M3087BFLAGP#U5 is part of the base M32C/87 variant, making it suitable for automotive gateway or industrial dual-bus applications. The M3087BFLAGP#U5 CAN pins are mapped to P8_2/P8_3 (CAN0) and P9_5/P9_6 (CAN1).

What package type and pin count does the M3087BFLAGP#U5 use?

The M3087BFLAGP#U5 uses a 144-pin plastic 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 datasheet. This package provides full access to all peripherals, including 34 ADC channels, dual CAN, seven UARTs, and the complete 16-bit intelligent I/O set. The "GP" suffix in the part number explicitly denotes the 144-pin LQFP variant, distinguishing it from 100-pin QFP ("FP") or LQFP ("GP") alternatives in the same family.

How much embedded memory does the M3087BFLAGP#U5 integrate?

The M3087BFLAGP#U5 integrates 1 MB of on-chip flash memory for program storage plus an additional 4 KB of dedicated data flash memory for parameter retention, along with 48 KB of RAM. This memory configuration is documented in Table 1.5 under the M32C/87 Group product list. The flash supports erase/program cycles at 3.3 V ±0.3 V or 5.0 V ±0.5 V, and includes ROM code protection and ID code verification for secure firmware deployment. All memory resources are directly accessible by the M32C/80 CPU core in the M3087BFLAGP#U5.

What is the operating temperature range for the M3087BFLAGP#U5?

The M3087BFLAGP#U5 is rated for an operating ambient temperature range of –20°C to +85°C, as stated in Tables 1.1 and 1.2 of the Renesas datasheet. This qualifies it for standard industrial applications without thermal derating. An optional –40°C to +85°C grade is available for extended environments, but the base M3087BFLAGP#U5 part shipped by Aetrix Electronics meets the –20°C to +85°C specification. This range aligns with Renesas' "Standard" quality grade, intended for office equipment, communications gear, and industrial robots - consistent with the intended use of the M3087BFLAGP#U5.
