FAQ
Is MB91F587LAPMC-GTK5E1 pin-compatible with other FR-family MCUs?
No - MB91F587LAPMC-GTK5E1 uses a unique 100-pin LQFP footprint optimized for its dual-CAN and LIN peripherals. While other FR devices share architectural similarities, pin assignments for CAN, ADC, and debug interfaces differ significantly across models. Migration requires PCB redesign and firmware adaptation.
Does this MCU support ISO 26262 ASIL-B compliance out of the box?
MB91F587LAPMC-GTK5E1 includes hardware features required for ASIL-B implementation - such as ECC flash, parity RAM, windowed WDT, and CRC unit - but full compliance depends on system-level integration, software safety mechanisms, and certification documentation provided by the end-user's safety case.
What debug tools are officially supported for this part?
Fujitsu's FINE™ debug interface is supported by the official FDT-5000 debugger and compatible third-party tools like Lauterbach TRACE32. The device does not support JTAG; instead, it uses Fujitsu's proprietary 4-wire serial debug protocol with real-time trace capability and non-intrusive breakpoints.
Can the on-chip flash be programmed in-system via CAN or LIN?
Yes - the MB91F587LAPMC-GTK5E1 supports in-system programming (ISP) via CAN using Fujitsu's standardized bootloader protocol. LIN-based ISP is not implemented; however, LIN can be used to trigger CAN-initiated firmware updates or enter bootloader mode through dedicated GPIO sequences.
