IS61WV5128EDBLL IS64WV5128EDBLL 512K x 8 HIGH SPEED ASYNCHRONOUS NOVEMBER 2011 CMOS STATIC RAM WITH ECC DESCRIPTION FEATURES The I S S I IS61/64WV5128EDBLL is a high-speed, High-speed access time: 8, 10 ns 4,194,304-bit static RAMs organized as 524,288 words by Low Active Power: 85 mW (typical) 8 bits. It is fabricated using ISSI s high-performance CMOS Low Standby Power: 7 mW (typical) technology. This highly reliable process coupled with inno- CMOS standby vative circuit design techniques, yields high-performance and low power consumption devices. Single power supply Vdd 2.4V to 3.6V (10 ns) When CE is HIGH (deselected), the device assumes a Vdd 3.3V 10% (8 ns) standby mode at which the power dissipation can be re- Fully static operation: no clock or refresh duced down with CMOS input levels. required Easy memory expansion is provided by using Chip Enable Three state outputs and Output Enable inputs, CE and OE. The active LOW Industrial and Automotive temperature support Write Enable (WE) controls both writing and reading of the memory. Lead-free available Error Detection and Error Correction The IS61/64WV5128EDBLL is packaged in the JEDEC standard 44-pin TSOP-II, 36-pin SOJ and 36-pin Mini BGA (6mm x 8mm).
