Renesas M3087BFLBGP#U3

Overview

M3087BFLBGP#U3 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 operates at up to 32 MHz (VCC1 = 4.2–5.5 V), supports 16-Mbyte external bus expansion, and integrates dual 8-bit D/A converters, 10-bit A/D converter with 34 channels, and five UARTs - used in industrial motor control and office automation systems.

For engineers reviewing the M3087BFLBGP#U3 datasheet, M3087BFLBGP#U3 pinout, M3087BFLBGP#U3 application, or M3087BFLBGP#U3 equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, absence of CAN interface, 32 MHz max clock with 31.3 ns instruction cycle, integrated three-phase motor control timers, and support for wait/stop low-power modes.

Technical Context

The M3087BFLBGP#U3 implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit). Its memory architecture includes on-chip flash with ROM code protection, 48 KB RAM, and configurable external bus interface supporting 8-/16-bit data width, 1–7 wait states, and four chip selects.

Peripheral integration includes Timer A (5×16-bit) with PWM and 2-phase encoder input, Timer B (6×16-bit) for pulse measurement, DMAC (4-channel cycle-steal) and DMACII (burst/chain transfer), CRC-CCITT engine, X/Y converter, and intelligent I/O with 16-channel waveform generation and 8-channel input capture - all optimized for deterministic real-time control in embedded systems.

FAQ

Does M3087BFLBGP#U3 support CAN communication?

No, M3087BFLBGP#U3 is part of the M32C/87B variant, which explicitly omits CAN modules per Renesas documentation (Table 1.7 and Note 5 in Figure 1.2). Pins P8_2/P8_3 and P9_5/P9_6 retain CAN signal names for pin compatibility within the family but are non-functional in this part. For CAN-enabled variants, consider M3087BFLGP (M32C/87) or M3087BFLAGP (M32C/87A).

What is the maximum operating frequency and corresponding supply voltage range for M3087BFLBGP#U3?

M3087BFLBGP#U3 achieves 32 MHz maximum operation at VCC1 = 4.2–5.5 V, delivering a minimum instruction execution time of 31.3 ns. At lower supply voltages (3.0–5.5 V), it operates up to 24 MHz with 41.7 ns minimum cycle time. VCC2 must be maintained between 3.0 V and VCC1 in all cases.

How many A/D converter channels does M3087BFLBGP#U3 support, and under what conditions?

M3087BFLBGP#U3 supports 34 channels of 10-bit A/D conversion in single-chip mode, as confirmed in Table 1.1 and Figure 1.2 notes. This full channel count is only available when the device is configured in single-chip mode; memory expansion or microprocessor modes reduce it to 18 channels. The A/D includes sample-and-hold for simultaneous multi-channel acquisition.

What package type and dimensions does M3087BFLBGP#U3 use?

M3087BFLBGP#U3 uses the PLQP0144KA-A package: a 144-pin plastic LQFP with 20 mm × 20 mm body size and 0.5 mm lead pitch. This matches the 144P6Q-A designation in Renesas' product numbering system (Figure 1.1) and is distinct from the 100-pin variants (PLQP0100KB-A or PRQP0100JB-A).

Does M3087BFLBGP#U3 include on-chip debug and flash reprogramming capability?

Yes, M3087BFLBGP#U3 includes full on-chip debug support and on-board flash reprogramming capability, as specified in Table 1.2 and Table 1.7. These features enable in-system firmware updates and real-time debugging without external emulators, with security enforced via ROM code protect and ID code check mechanisms.
