FAQ
What is the maximum operating frequency and supply voltage range for the M3087BFKGP#U5?
The M3087BFKGP#U5 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, and at 24 MHz with VCC1 from 3.0 V to 5.5 V. VCC2 must be maintained between 3.0 V and VCC1. These ranges ensure stable execution of real-time control loops while supporting legacy 5 V system designs and newer 3.3 V interfaces. The M3087BFKGP#U5 meets these specifications across its rated -20°C to +85°C ambient temperature range.
Does the M3087BFKGP#U5 include on-chip debug and flash programming capability?
Yes, the M3087BFKGP#U5 integrates full on-chip debug functionality and supports on-board flash reprogramming via UART or dedicated debug interface. This enables in-system firmware updates, real-time variable inspection, and breakpoint debugging without requiring external emulators. The M3087BFKGP#U5 also includes ROM code protection and ID code check features to secure intellectual property during production programming and field deployment.
How many CAN channels does the M3087BFKGP#U5 support, and what version of the CAN specification is implemented?
The M3087BFKGP#U5 supports two independent CAN 2.0B-compliant channels, each with 16 message slots and full protocol handling including identifier masking, error framing, and automatic retransmission. Unlike the M32C/87A (one channel) and M32C/87B (no CAN), the M3087BFKGP#U5 is the only variant in the family with dual-CAN capability - making it suitable for applications requiring redundant bus communication or subsystem segregation. The M3087BFKGP#U5 does not support CAN FD.
What package type and pin count does the M3087BFKGP#U5 use?
The M3087BFKGP#U5 is housed in a 144-pin plastic LQFP package designated PLQP0144KA-A (144P6Q-A), measuring 20 mm × 20 mm with 0.5 mm pitch and RoHS-compliant lead-free finish. This package provides full access to all peripherals including dual CAN, 34-channel ADC, and 16-bit intelligent I/O timers. Pin assignments are documented in Renesas document REJ03B0127-0151, Figure 1.3 and Tables 1.8–1.9 for the M3087BFKGP#U5.
What is the flash memory capacity and endurance rating of the M3087BFKGP#U5?
The M3087BFKGP#U5 contains 768 KB of main flash memory plus an additional 4 KB of dedicated data flash memory, both erasable and programmable at 3.3 V ± 0.3 V or 5.0 V ± 0.5 V. Flash endurance is rated for 100 write/erase cycles across all areas - sufficient for factory calibration storage and infrequent field updates. The M3087BFKGP#U5 also supports ROM code protection and ID code verification to prevent unauthorized access or cloning of firmware assets.
