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