Renesas M3087BFLBGP#U5

Overview

M3087BFLBGP#U5 from Renesas Electronics is a 144-pin LQFP microcontroller in the M32C/87B group, featuring the M32C/80 CPU core, 1 MB + 4 KB data flash, 48 KB RAM, and no CAN module. It supports 32 MHz operation at 4.2–5.5 V, delivers 10-bit A/D conversion across 34 channels, and integrates dual 8-bit D/A converters, five 16-bit Timer A units, and six 16-bit Timer B units for motor control and PWM generation - deployed in industrial automation and office equipment.

For engineers reviewing the M3087BFLBGP#U5 datasheet, M3087BFLBGP#U5 pinout, M3087BFLBGP#U5 application, or M3087BFLBGP#U5 equivalent, key selection considerations include its 144-pin PLQP0144KA-A package, absence of CAN interfaces, full 34-channel ADC support (144-pin variant), on-chip PLL and four DMAC channels, and compatibility with single-chip, memory expansion, and microprocessor operating modes.

Technical Context

The M3087BFLBGP#U5 implements the M32C/80 16-bit CPU core with 108 basic instructions and multiplier support for 16×16→32-bit operations and 16×16+48→48-bit multiply-add. Its clock system includes main/sub oscillators, on-chip oscillator, and PLL frequency synthesizer with selectable division ratios (1–16).

It provides 16-Mbyte external address space with configurable bus width (8/16-bit), up to 7 wait states, and four chip select outputs. Peripheral integration includes UART0–UART4 (5 channels), I²C, IrDA, HDLC, and intelligent I/O with input capture (8 channels) and output compare (16 channels) - all mapped to dedicated pins in the 144-pin LQFP layout.

FAQ

Does M3087BFLBGP#U5 support CAN communication?

No, M3087BFLBGP#U5 is an M32C/87B-series device and explicitly excludes CAN modules per Renesas documentation. While CAN-related pins (e.g., P8_2, P8_3) are physically present on the 144-pin package, they are not functional in this variant. Engineers requiring CAN must select M32C/87 (dual-channel) or M32C/87A (single-channel) variants such as M3087BFLGP or M3087BFLAGP.

What is the maximum ADC channel count supported by M3087BFLBGP#U5?

M3087BFLBGP#U5 supports 34 analog input channels in single-chip mode, as confirmed in Table 1.1 and Figure 1.2 of the Renesas REJ03B0127-0151 datasheet. This full complement is enabled only in the 144-pin LQFP package; the 100-pin variants support 26 channels. All channels feature 10-bit resolution with sample-and-hold capability.

Which package type does M3087BFLBGP#U5 use?

M3087BFLBGP#U5 uses the 144-pin plastic LQFP package designated PLQP0144KA-A (also referenced as 144P6Q-A), measuring 20 mm × 20 mm with 0.5 mm lead pitch. This is confirmed in Table 1.7 and Figure 1.3 of the official Renesas datasheet REJ03B0127-0151.

Can M3087BFLBGP#U5 operate at 3.3 V supply?

Yes, M3087BFLBGP#U5 supports 24 MHz operation with VCC1 = 3.0–5.5 V and VCC2 = 3.0 V to VCC1, enabling reliable 3.3 V system design. At 3.3 V, typical current consumption is 23 mA (active), 45 μA (wait mode), and 0.8 μA (stop mode), as specified in Tables 1.1 and 1.2 of the Renesas datasheet.

Does M3087BFLBGP#U5 include on-chip debug capability?

Yes, M3087BFLBGP#U5 includes full on-chip debug support per Renesas documentation, enabling real-time breakpoint setting, register inspection, and flash memory programming via the standard debug interface. This capability is listed under "Debug functions" in Table 1.1 and Table 1.2, and is compatible with Renesas E1/E20 emulators and standard IDE toolchains.
