71321SA55J Description

Short technical summary and product information.

The Renesas Electronics America Inc 71321SA55TF is a volatile dual-port SRAM with a total memory capacity of 16Kbit. It is organized as 2K words by 8 bits per word and features a fast parallel interface for data transfer. This SRAM IC has an access time and write cycle time of 55ns, making it suitable for applications requiring quick data exchange.

The device operates within a supply voltage range of 4.5V to 5.5V and is designed for a commercial temperature range of 0°C to 70°C. It is housed in a compact 64-TQFP surface mount package with dimensions of 10mm x 10mm. The dual-port architecture allows for two independent access ports, enabling asynchronous and simultaneous read/write operations without conflicts.

This SRAM is best suited for embedded systems, networking equipment, and data buffering applications where simultaneous memory access by multiple processors or controllers is necessary. Selection should consider the 4.5V to 5.5V operating voltage and the 0°C to 70°C temperature requirements. Handling considerations for Moisture Sensitivity Level (MSL) 3 are also important for assembly.
