The DF71476AK64FPV is an obsolete Renesas SH7147 automotive microcontroller featuring a 64MHz 32-bit SH-2 CPU, 512KB of flash memory, 16KB of RAM and one CAN channel. Its 5V architecture, 100-pin LFQFP package and -40°C to +125°C operating range make it relevant to qualified legacy chassis, safety and embedded control systems.

Renesas lists both DF71476AK64FPV and the SH7147 group as Obsolete. DataStorageIC can check legacy inventory for repair, repeat-production and lifecycle-support requirements. Available quantity, date code, condition and traceability must be confirmed for the specific lot offered.

DF71476AK64FPV Specifications

Renesas marks DF71476AK64FPV as obsolete, and the SH7147 product table shows manufacturer stock as unavailable. Remaining supply is therefore generally limited to legacy or aftermarket inventory.

Renesas recommends the RH850/P1x Series for new SH7147 designs. This is a migration direction rather than a pin-compatible replacement. A redesign should compare:

SH-2 instruction set and firmware portability;

flash, RAM and startup behavior;

CAN controller implementation and communication timing;

timer, ADC, DMA, interrupt and I/O requirements;

5V interfaces, clocking and power sequencing;

package footprint and pin assignment;

compiler, debugger, programmer and production-test tools;

automotive qualification and system revalidation.

For a short-term repair or production gap, sourcing the exact DF71476AK64FPV may minimize engineering changes. Long-term programs should evaluate RH850 migration and final-lifetime inventory in parallel.

Frequently Asked Questions

Is DF71476AK64FPV obsolete?

Yes. Renesas lists the exact part number and the SH7147 group as Obsolete. The manufacturer's product table currently shows this device as out of stock.

What CPU and memory does DF71476AK64FPV have?

It integrates a 64MHz 32-bit SH-2 CPU, 512KB of flash program memory and 16KB of RAM. It does not include data flash.

How many CAN channels does DF71476AK64FPV provide?

It provides one CAN channel. This is important when comparing it with DF71426AK64FPV, which Renesas specifies with two CAN channels.

What package and temperature range does it use?

DF71476AK64FPV uses a 100-pin LFQFP package measuring 14 × 14 × 1.7mm with a 0.5mm pitch. Its specified operating temperature range is -40°C to +125°C.

How does DF71476AK64FPV differ from DF71476BD80FPV?

DF71476AK64FPV is the 64MHz, -40°C to +125°C version. DF71476BD80FPV operates at up to 80MHz but is specified for -40°C to +85°C. A substitution requires full electrical and system validation.

Is RH850/P1x a drop-in replacement?

No. Renesas recommends RH850/P1x for new designs, but it is a migration platform rather than a pin-compatible replacement. Hardware, firmware, development tools and qualification must be reviewed.
