Overview
MB91306RPFV-G-JNE1 from Infineon Technologies is a 32-bit ROMless microcontroller based on the FR-V architecture, featuring 120 LQFP package, 1.8 V core supply, 32 KB SRAM, and integrated JTAG debug interface. It targets real-time control in automotive body electronics and industrial motor control systems.
For engineers reviewing the MB91306RPFV-G-JNE1 datasheet, MB91306RPFV-G-JNE1 pinout, MB91306RPFV-G-JNE1 application, or MB91306RPFV-G-JNE1 equivalent, key selection criteria include its FR-V CPU clock capability (up to 100 MHz), SRAM-only execution model, LQFP-120 thermal profile, and automotive-grade AEC-Q100 qualification status.
Technical Context
The MB91306RPFV-G-JNE1 implements Fujitsu's FR-V v2.0 32-bit RISC core with dual-issue superscalar pipeline and hardware loop control. It supports real-time interrupt response with 16 priority levels and includes on-chip peripherals such as 32-bit timer/counters, UART, I²C, and CAN 2.0B controller.
Its ROMless architecture requires external boot code loading via JTAG or serial interface before operation. The device operates across −40°C to +125°C ambient temperature and meets AEC-Q100 Grade 2 reliability requirements for automotive under-hood applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit ROMless automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RH850/F1L-M (Renesas) | Integrated flash (512 KB), higher peripheral integration (ADC, CAN FD), 40-pin smaller footprint | Better suited for new designs requiring self-contained boot and mixed-signal capability | Select if flash-based boot and lower BOM count outweigh need for FR-V toolchain continuity |
| TC1766 (Infineon) | TriCore architecture, 2 MB flash, higher performance (133 MHz), larger LQFP-144 package | Targets high-end powertrain ECUs with ASIL-B functional safety requirements | Choose when ISO 26262 compliance and >100 MHz deterministic processing are mandatory |
Compared with RH850/F1L-M and TC1766, the MB91306RPFV-G-JNE1 offers unique value in legacy FR-V ecosystem migration paths and thermal efficiency in constrained 120-pin LQFP layouts, but lacks on-chip nonvolatile storage and functional safety certification.

FAQ
Does MB91306RPFV-G-JNE1 include on-chip flash memory?
No. The MB91306RPFV-G-JNE1 is ROMless and contains only 32 KB of on-chip SRAM. Firmware must be loaded externally via JTAG or serial interface at startup. This architecture supports field-upgradable code but requires a bootloader implementation in external memory or host processor.
What debug interfaces does MB91306RPFV-G-JNE1 support?
The device supports IEEE 1149.1-compliant JTAG for boundary scan testing and real-time debugging, including hardware breakpoints, watchpoints, and register visibility. No SWD or cJTAG interface is implemented; JTAG is the sole standardized debug access method.
Is MB91306RPFV-G-JNE1 qualified for automotive applications?
Yes. It is qualified to AEC-Q100 Grade 2 (−40°C to +125°C), with test reports covering HTOL, ESD, and thermal cycling. It is intended for non-safety-critical automotive applications such as body control and HVAC, but not certified to ISO 26262 ASIL levels.
Can MB91306RPFV-G-JNE1 operate without external memory?
No. As a ROMless MCU, it requires external code loading before execution. While it can run entirely from its 32 KB SRAM after boot, no persistent storage exists on-die; external SPI Flash or host processor initialization is mandatory for autonomous operation.
