Nec B58944 Datasheet 2021

The NEC B58944 is ; it was specifically qualified and supplied by NEC for Bosch engine control units (ECUs) . As a result, you will find the chip inside many common Bosch ECU families, including:

: Typically indicated by the suffix (e.g., "-70L" denotes a 70ns access time). Datasheet Availability

256K bit Static RAM (typically organized as 32K x 8-bit). nec b58944 datasheet 2021

When replacing a degraded unit, use a temperature-controlled hot air rework station. Given the thick multi-layer PCB design of automotive ECUs, applying a localized pre-heater beneath the board reduces thermal shock. Use high-quality leaded or lead-free solder paste depending on environmental compliance needs, ensuring a complete wetting of the 28 SOP pins to avoid cold joint fractures caused by engine vibration. If you are currently diagnosing an ECU board, let me know:
