Product details

Overview

M3087BFLGP#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, dual CAN 2.0B modules, and operation up to 32 MHz at 4.2–5.5 V. It targets industrial motor control, office automation, and communication equipment requiring integrated timing, PWM, and serial interfaces.

For engineers reviewing the M3087BFLGP#U5 datasheet, M3087BFLGP#U5 pinout, M3087BFLGP#U5 application, or M3087BFLGP#U5 equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, dual-CAN capability, 34-channel 10-bit ADC, on-chip dead-time timer for 3-phase inverter control, and support for wait/stop low-power modes.

Technical Context

The M3087BFLGP#U5 implements the M32C/80 core with 16×16→32-bit multiplier and 16×16+48→48-bit multiply-add instructions, enabling efficient real-time control. Its external bus supports 16-Mbyte address space with configurable wait states, separate/multiplexed bus formats, and 8-/16-bit data width-critical for memory expansion in embedded systems.

It integrates two independent CAN 2.0B controllers (16-slot × 2 channels), five UARTs with IrDA/GCI/IEBus options, six 16-bit timers (Timer A/B) supporting PWM, encoder input, and 3-phase motor control using dedicated hardware logic across Timer A1/A2/A4 and Timer B2, plus an on-chip dead-time timer.

FAQ

What is the maximum operating frequency and supply voltage range for the M3087BFLGP#U5?

The M3087BFLGP#U5 operates at up to 32 MHz with VCC1 = 4.2 V to 5.5 V, delivering a 31.3 ns minimum instruction cycle time. At lower frequencies (24 MHz), it supports VCC1 = 3.0 V to 5.5 V, enabling flexible power design across 3.3 V and 5 V systems. The M3087BFLGP#U5 also specifies VCC2 = 3.0 V to VCC1, ensuring stable I/O and internal logic operation across the full supply range.

Does the M3087BFLGP#U5 support CAN FD or only classical CAN 2.0B?

The M3087BFLGP#U5 supports only CAN 2.0B (ISO 11898-1:2003), with two independent controllers each implementing 16 message slots and full protocol handling. It does not support CAN FD features such as flexible data-rate or extended payload length. For CAN FD migration, engineers should evaluate Renesas' RX66T or RA6T2 families, as the M3087BFLGP#U5's CAN peripheral is fixed to classical CAN timing and frame structure.

How many ADC channels are accessible in the M3087BFLGP#U5, and what is their resolution?

The M3087BFLGP#U5 provides 34 channels of 10-bit successive-approximation ADC in single-chip mode, with sample-and-hold functionality. This configuration is enabled in the default operating mode and matches the 144-pin package's full analog input allocation. The M3087BFLGP#U5's ADC supports simultaneous sampling triggers from timers or external events-critical for multi-axis current sensing in motor control applications.

What debug and programming interfaces does the M3087BFLGP#U5 include?

The M3087BFLGP#U5 integrates full on-chip debug (OCD) via JTAG interface, supporting real-time breakpoints, register inspection, and flash memory programming without external emulators. It also enables in-system programming (ISP) through its built-in bootloader, allowing firmware updates over UART or CAN after deployment. These capabilities are native to the M3087BFLGP#U5 silicon and require no additional debug hardware beyond standard JTAG adapters.

Is the M3087BFLGP#U5 pin-compatible with other members of the M32C/87 Group?

Yes-the M3087BFLGP#U5 uses the PLQP0144KA-A (144-pin LQFP) package shared across all 144-pin M32C/87 variants (e.g., M30878FJGP, M30875FHGP). Pin functions are identical within the same package type, though peripheral enablement (e.g., CAN modules) differs by part number. The M3087BFLGP#U5's pinout matches Table 1.8 and Figure 1.3 in the official Renesas documentation, confirming mechanical and electrical compatibility with drop-in replacement of other 144-pin M32C/87 flash variants.
