Product details
Overview
M3087BFKBGP#U3 from Renesas Electronics is a 144-pin LQFP microcontroller in the M32C/87B family, featuring the M32C/80 CPU core, 768 KB + 4 KB data flash memory, 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 UART interfaces - deployed in industrial motor control and office automation systems.
For engineers reviewing the M3087BFKBGP#U3 datasheet, M3087BFKBGP#U3 pinout, M3087BFKBGP#U3 application, or M3087BFKBGP#U3 equivalent, key selection criteria include its 144-pin LQFP package, absence of CAN peripherals, 32 MHz max clock, 10-bit ADC channel count, and support for three-phase inverter control using Timer A/B resources.
Technical Context
The M3087BFKBGP#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, debug-enabled on-board reprogramming, and configurable external bus interface supporting 8-/16-bit data width, 1–7 wait states, and four chip selects.
Peripheral integration centers on deterministic real-time control: five UARTs (including IrDA and I²C modes), two 8-bit DACs, a 10-bit 34-channel ADC with sample-and-hold, six 16-bit Timer B units for pulse measurement, and five 16-bit Timer A units supporting PWM, encoder input, and 3-phase motor control via dedicated dead-time logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP | RX66T 32-bit core, 120 MHz, 1 MB flash, integrated FPU, no native 3-phase motor timer block | Requires software-based dead-time insertion; higher performance but larger code footprint | Select when migrating to 32-bit platform with need for floating-point math and Ethernet connectivity |
| M30879FKBGP | Same M32C/87B family, 100-pin LQFP, 768 KB + 4 KB flash, 48 KB RAM, identical peripheral set | Reduced I/O count (85 CMOS vs. 121), fewer ADC channels (26 vs. 34), no P11–P15 ports | Choose for space-constrained designs where full 144-pin I/O and 34-channel ADC are unnecessary |
Compared with R5F566TEADFP and M30879FKBGP, the M3087BFKBGP#U3 delivers optimal balance of deterministic 3-phase motor control, compact 16-bit code density, and full 144-pin I/O - making it ideal for cost-sensitive industrial drives where hardware-accelerated timing is critical and migration to 32-bit is premature.

FAQ
Does M3087BFKBGP#U3 support CAN communication?
No, M3087BFKBGP#U3 belongs to the M32C/87B variant, which explicitly excludes CAN modules per Renesas documentation. While CAN-related pins (e.g., P8_2/P8_3) are physically present on the 144-pin LQFP package, they are unconnected internally and function only as general-purpose I/O or alternate UART signals. Engineers must select M3087BFLGP or M3087BFKGP for CAN 2.0B support.
What is the maximum ADC sampling rate achievable with M3087BFKBGP#U3?
The M3087BFKBGP#U3 supports a maximum ADC conversion time of 1.2 μs per 10-bit sample under optimal conditions (VCC = 5 V, internal clock source). With sequential channel scanning and no inter-channel delay, this yields up to ~833 kSPS aggregate throughput across all 34 channels - though practical sustained rates depend on software overhead and trigger source configuration.
Can M3087BFKBGP#U3 operate from a 3.3 V supply?
Yes, M3087BFKBGP#U3 supports dual-supply operation: VCC1 = 3.0–5.5 V and VCC2 = 3.0 V to VCC1. At 24 MHz, it operates reliably across VCC1 = 3.0–5.5 V; at 32 MHz, minimum VCC1 is 4.2 V. The 3.3 V supply is fully valid for 24 MHz operation and all low-power modes including stop mode (0.8 μA).
How many UART interfaces does M3087BFKBGP#U3 provide, and what protocols do they support?
M3087BFKBGP#U3 provides five UART interfaces (UART0–UART4), each supporting clock-synchronous and asynchronous serial communication. Additional protocol support includes I²C bus mode, IrDA physical layer, HDLC data processing, and optional IEBus - all implemented in hardware without CPU intervention. UART5 is not available in the M32C/87B variant.
Is on-chip debug supported for M3087BFKBGP#U3 during flash programming?
Yes, M3087BFKBGP#U3 includes full on-chip debug capability compliant with Renesas E8/E8a debug interface standards. This enables real-time breakpoint setting, register inspection, and in-system flash programming - including secure reprogramming of the 768 KB main flash and 4 KB data flash areas while the device remains soldered on the target board.
