If the B58944 is a switching regulator (e.g., similar to NEC µPC494 PWM controller), then specifications would differ drastically – switching frequency ~40kHz, output current up to 3A external transistor. NEC B58944 Datasheet: A Comprehensive Review of the

SRAM (Static Random Access Memory)

Technically, the B58944 is an chip. It is frequently identified as an automotive-grade equivalent or a rebranded version of the μPD43256BGU-70L . Capacity: 256 Kib (32K x 8 bits). If external: Maintain 50-ohm impedance trace
