Use the exact part number in your searches to filter out noise and find the correct memory chip for your repairs, whether in an automotive ECU or another embedded system.

The vast majority of references point to a 256-Kbit CMOS SRAM from NEC. This is the core of our guide. The part numbers found are consistently:

Users on ECU tuning forums have specifically identified the B58944 inside Nissan X-Trail diesel ECUs (model EDC 16CP33-6.7), noting that it is located next to an MZP665 BGA processor. This chip is integral to the ECU's operation and is a common point of failure in these modules. - Many distributors list the component under the

ECU Fix Tools: Provides practical context for the chip's use in automotive repair and ECU maintenance. Critical Considerations for Repair If you are using this chip for ECU repair:

Always ensure you are looking for the version that matches the physical IC package (SO-28 or QFP) and speed class needed for your specific application. Troubleshooting and Handling

The (often cross-referenced with Bosch numbering or associated with the D43256BGU-70Y component) is a highly specialized, surface-mount integrated circuit (IC) predominantly utilized as an Engine Control Unit (ECU) driver chip in automotive systems. Finding a reliable, free technical datasheet for older proprietary or manufacturer-specific automotive components like the B58944 can be difficult. Automotive ICs are typically tightly locked behind commercial distribution firewalls or restricted to original equipment manufacturers (OEMs).
