The IS62WV51216HBLL-45TLI is an 8Mbit (512K x 16-bit) ultra-low-power asynchronous SRAM from ISSI operating at 2.2V to 3.6V with 45 ns access time. The HBLL variant features the lowest standby current in the ISSI SRAM portfolio (~1.5 \u00b5A typical) with industrial temperature grade, making it ideal for battery-backed applications requiring months or years of data retention.<\/p>\n

The HBLL variant achieves the industry's lowest standby current of 1.5 \u00b5A typical and data retention down to 1.2V, enabling years of battery-backed data retention in industrial and telecom applications. Upper\/lower byte control via LB#\/UB# provides flexible 8-bit or 16-bit access.","working_principle":"Fully static asynchronous SRAM with ultra-low-power design.
