Nec B58944 Datasheet [top] -

If you are sourcing a replacement chip for circuit board repair, you can look for equivalent 32K x 8 asynchronous CMOS SRAMs with a 70ns access speed in a 28-pin SOP package. Direct architectural equivalents include:

: Provides general product details, package information, and stock status. nec b58944 datasheet

: The bi-directional bus lines that transmit sensor configurations, injector timings, and diagnostic trouble codes (DTCs). If you are sourcing a replacement chip for

: Power the ECU on a bench rig at 12V. Use a thermal camera to spot if the B58944 glows rapidly above 70°C, indicating an internal short circuit. : Power the ECU on a bench rig at 12V

Including ME7.4.4, ME7.5, and ME7.9.6 (common in Honda and Volkswagen/Audi groups).
