The device provides 10ns maximum access time, making it suitable for zero-wait-state operation with fast microprocessors and DSPs. The device operates from a single 3.3V supply (2.4V to 3.6V range), with active current of 115mA typical and standby current of only 3mA when deselected. Upper and lower byte enable pins (UB# and LB#) allow independent access to each byte of the 16-bit data word. The device is fully static and requires no external clocks or refresh circuitry. The -10MLI suffix indicates 10ns speed grade, TSOP-II package, and industrial temperature range (-40C to +85C).","working_principle":"The IS61WV51216BLL-10MLI is an asynchronous 6-transistor (6T) CMOS static RAM. (1) Memory Cell: Each bit is stored in a 6-transistor cross-coupled inverter latch. The two stable states represent logic 0 and 1. Unlike DRAM, the data is retained without periodic refresh as long as power is applied. (2) Read Operation: When CE# and OE# are low, the address decoders select one of 512K word lines. The selected 16 memory cells drive the bit lines, and the sense amplifiers detect the small voltage differences. The output buffers drive the data onto the I\/O pins within 10ns of address valid. (3) Write Operation: When CE# and WE# are low, the input data on the I\/O pins is driven onto the bit lines and written into the selected memory cells, overwriting the previous data. (4) Byte Control: The LB# and UB# pins independently enable the lower byte (I\/O0-7) and upper byte (I\/O8-15), allowing byte-wide or word-wide write operations.","pin_description":"
