The B58944 is housed in a , a surface-mount design featuring 28 pins intended for efficient PCB integration. Technically, it is closely related to the D43256BGU series, which is a 256K-bit (32K x 8) CMOS static RAM. Its primary role in an ECU environment is to handle data storage or engine-driving functions that are essential for real-time vehicle management. Package Type: SOP-28 Manufacturer: NEC (often branded or used in Bosch modules)
Supplied as an empty hardware chip (requires no independent firmware programming; operations are driven completely by the master ECU MCU) Understanding the SOP-28 Pin Configuration
: It is integrated into several generations of Bosch hardware, including the ME7.4.4, ME7.5, ME7.5.10, ME7.9.6, ME7.9.20, EDC7, and EDC16 ECU platforms. These modules manage engine mapping across common consumer vehicle brands like Volkswagen, Audi, Honda, and Iveco. nec b58944 datasheet
