Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit RISC microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F7049FJ40V | Same SH-2 core and pinout, but 128 KB mask ROM instead of 256 KB Flash - no field reprogramming capability. | Suitable only for volume-manufactured, unchanging firmware deployments where cost-per-unit outweighs flexibility. | Select HD64F7049FJ40V only when firmware is finalized and mask ROM economics justify tooling investment. |
| R5F72047GDFP | Successor RH850/F1L series part with enhanced CAN FD support, 64 KB RAM, and updated debug interface - not pin-compatible. | Required for new designs needing CAN FD, ASIL-B compliance, or extended lifecycle support beyond 2025. | Choose R5F72047GDFP for greenfield projects requiring long-term availability and functional safety extensions. |
Compared with HD64F7047FJ40V, HD64F7049FJ40V trades field-upgradability for lower unit cost in fixed-function roles, while R5F72047GDFP offers modern peripherals and safety features at the expense of PCB redesign and firmware porting effort.

FAQ
What is the maximum operating frequency of the HD64F7047FJ40V?
The HD64F7047FJ40V operates at a maximum CPU clock frequency of 40 MHz, achieved using its on-chip PLL clock pulse generator with external crystal or clock input. This frequency is specified under 3.0–3.6 V supply and −40°C to +85°C ambient conditions, and enables 38 MIPS performance for real-time deterministic execution in the HD64F7047FJ40V.
Does the HD64F7047FJ40V include on-chip Flash memory, and what is its size?
Yes, the HD64F7047FJ40V integrates 256 KB of on-chip Flash memory organized in 1 KB erasable sectors. This Flash is used for program storage and supports in-system programming via on-chip boot ROM routines, making it suitable for field firmware updates without external programming hardware in the HD64F7047FJ40V.
How many CAN interfaces does the HD64F7047FJ40V support, and what protocol versions are implemented?
The HD64F7047FJ40V supports two independent CAN controllers compliant with CAN 2.0B (ISO 11898), each with dedicated TX/RX pins, message buffers, and acceptance filtering. These controllers operate concurrently and are fully integrated into the HD64F7047FJ40V's interrupt and DMA subsystems for zero-CPU-overhead message handling.
What package type and pin count does the HD64F7047FJ40V use?
The HD64F7047FJ40V uses a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, conforming to JEDEC MS-026AC. This package provides full access to all I/O, memory bus, and peripheral signals, and is compatible with standard SMT assembly processes used for the HD64F7047FJ40V in industrial and automotive production.
Is the HD64F7047FJ40V suitable for automotive applications, and what quality grade is assigned?
The HD64F7047FJ40V is classified as a Renesas "Standard" quality grade device, qualified for automotive body electronics such as door modules and lighting controllers-but not for safety-critical powertrain or ADAS functions. Its −40°C to +85°C operating range and AEC-Q100 stress testing alignment make it appropriate for non-life-support automotive applications per HD64F7047FJ40V documentation.
