Overview
M3087BFKGP#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, 768 KB + 4 KB data flash, 48 KB RAM, dual CAN 2.0B modules (16-slot × 2 channels), 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, analog conversion, and real-time I/O.
For engineers reviewing the M3087BFKGP#U3 datasheet, M3087BFKGP#U3 pinout, M3087BFKGP#U3 application, or M3087BFKGP#U3 equivalent, key selection considerations include its dual-CAN capability, 34-channel 10-bit ADC in single-chip mode, on-chip PLL and four clock sources, 16-bit timer A/B resources for PWM and encoder input, and support for external bus expansion with 16-Mbyte address space.
Technical Context
The M3087BFKGP#U3 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier supporting 16×16→32-bit multiply-add operations. Its memory architecture includes 768 KB main flash plus 4 KB dedicated data flash, enabling field reprogramming and parameter storage without erasing application code.
Peripheral integration includes two independent CAN 2.0B controllers (16 message slots each), five 16-bit Timer A units (supporting PWM, one-shot, and 2-phase encoder input), six 16-bit Timer B units (for pulse width/period measurement), and a DMAC with 43 trigger sources and dual transfer modes-enabling deterministic real-time response in motor and industrial control loops.

FAQ
What is the maximum operating frequency and supply voltage range for the M3087BFKGP#U3?
The M3087BFKGP#U3 operates at up to 32 MHz with VCC1 = 4.2 V to 5.5 V, delivering a minimum instruction execution time of 31.3 ns. At lower frequencies (24 MHz), it supports VCC1 = 3.0 V to 5.5 V, enabling flexible power design across industrial voltage rails. The M3087BFKGP#U3 also features separate VCC2 supply (3.0 V to VCC1) for I/O domains.
Does the M3087BFKGP#U3 support both CAN 2.0A and CAN 2.0B protocols?
Yes, the M3087BFKGP#U3 supports the full CAN 2.0B specification, including both standard (11-bit) and extended (29-bit) identifier frames. Its dual CAN controllers operate independently with dedicated 16-slot message buffers, enabling simultaneous handling of different network priorities or protocols. The M3087BFKGP#U3 does not implement CAN FD.
How many analog-to-digital converter channels does the M3087BFKGP#U3 provide, and what is their resolution?
The M3087BFKGP#U3 provides 34 channels of 10-bit analog-to-digital conversion in single-chip mode, with built-in sample-and-hold functionality. In memory expansion or microprocessor modes, it supports 18 channels. All channels are accessible via dedicated ANx_y pin names and configurable through the AD control registers in the M3087BFKGP#U3 peripheral set.
What debug and programming interfaces are available on the M3087BFKGP#U3?
The M3087BFKGP#U3 supports on-chip debug via the E8/E8a emulator interface and on-board flash reprogramming using the built-in bootloader. It includes ROM code protection and ID code check features to prevent unauthorized access. No JTAG port is present; debugging relies on Renesas' proprietary FINE interface compatible with standard E8 debug probes.
Is the M3087BFKGP#U3 pin-compatible with other members of the M32C/87 Group?
Yes, the M3087BFKGP#U3 shares the same 144-pin LQFP (PLQP0144KA-A) package and pinout with all other 144-pin M32C/87 variants-including M3087BFLGP and M3087BFKAGP-ensuring mechanical and electrical compatibility. Firmware portability is supported within the M32C/87 family, though feature availability (e.g., CAN channel count) varies by suffix ('B' = no CAN, 'A' = one CAN, base = dual CAN).
