Yes. Renesas officially lists DF71426BJ80FPV and the SH7147 group as obsolete. The manufacturer's product table currently shows the part as out of stock.
What CPU and memory does DF71426BJ80FPV have?
It uses a 32-bit SH-2 core operating at up to 80MHz, with 512KB of program flash and 16KB of RAM. It does not include separate data flash.
How many CAN channels are integrated?
DF71426BJ80FPV provides two CAN channels, which distinguishes it from some SH7147 variants that provide only one CAN channel.
What package does DF71426BJ80FPV use?
It uses a 100-pin LFQFP package measuring 14 × 14 × 1.7mm with a 0.5mm lead pitch.
Is there a direct replacement for DF71426BJ80FPV?
Renesas recommends the RH850/P1x Series for new designs, but it is not a direct pin-compatible substitute. Migration requires hardware, firmware and qualification work.
What information is needed for a stock quotation?
Provide the exact part number, quantity, acceptable date codes, delivery destination and any testing or traceability requirements. Stock should be confirmed at the time of RFQ.
