Product details

Overview

M3087BFLAGP#U3 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, and operation up to 32 MHz at 4.2–5.5 V. It integrates dual CAN 2.0B controllers, 34-channel 10-bit ADC, dual 8-bit DACs, and advanced motor control timers - deployed in industrial automation and office equipment.

For engineers reviewing the M3087BFLAGP#U3 datasheet, M3087BFLAGP#U3 pinout, M3087BFLAGP#U3 application, or M3087BFLAGP#U3 equivalent, key selection criteria include its 144-pin LQFP package, dual-CAN support (16-slot × 2 channels), 32 MHz max frequency with 31.3 ns instruction cycle, integrated 3-phase inverter control logic, and on-chip debug capability for embedded firmware development.

Technical Context

The M3087BFLAGP#U3 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 mode, with 16-Mbyte external address space and configurable bus interface (8-/16-bit width, 1–7 wait states).

Its peripheral set includes two independent DMAC units (DMAC and DMACII), seven UART channels (UART0–UART6), I²C, IrDA, HDLC, and optional IEBus - all managed via intelligent I/O with 16-bit timers supporting input capture (8 channels), output compare (16 channels), and 2-phase encoder input. The device lacks CAN functionality per specification (M32C/87B variant), confirming zero CAN modules.

FAQ

Does M3087BFLAGP#U3 include CAN controller hardware?

No. The M3087BFLAGP#U3 belongs to the M32C/87B variant, which explicitly omits CAN modules per Renesas documentation (Table 1.7 and Note 5 in REJ03B0127-0151). Pins P8_2/P8_3 and P9_5/P9_6 retain CAN-related labels for pin compatibility across the M32C/87 family but are non-functional in this part. The M3087BFLAGP#U3 provides UART, I²C, and IrDA instead.

What is the maximum clock frequency and corresponding supply voltage range for M3087BFLAGP#U3?

The M3087BFLAGP#U3 operates at up to 32 MHz when VCC1 is maintained between 4.2 V and 5.5 V. At 24 MHz, it supports a wider supply range of 3.0 V to 5.5 V. These specifications are confirmed in Tables 1.1 and 1.3 of the official datasheet REJ03B0127-0151 Rev.1.51.

How many analog-to-digital converter channels does M3087BFLAGP#U3 support?

In single-chip mode, the M3087BFLAGP#U3 supports 34 channels of 10-bit ADC with sample-and-hold. This count drops to 18 channels in memory expansion or microprocessor modes. All channels are accessible via dedicated ANx_y pin names (e.g., AN0_0 through AN0_7, AN15_0 through AN15_7) on the 144-pin LQFP package.

Is on-chip debug supported for M3087BFLAGP#U3 firmware development?

Yes. The M3087BFLAGP#U3 includes full on-chip debug capability compliant with Renesas E1/E20 emulators and CS+ IDE. Debug features include hardware breakpoints, real-time variable watch, and flash reprogramming - documented in Section 1.1.2 and Table 1.2 under "Debug functions".

What package type and dimensions does M3087BFLAGP#U3 use?

The M3087BFLAGP#U3 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 datasheet. Pin 1 location and mechanical dimensions are defined in the Renesas package outline document for PLQP0144KA-A.
