IS61WV12816EDBLL IS64WV12816EDBLL 128K x 16 HIGH SPEED ASYNCHRONOUS OCTOBER 2011 CMOS STATIC RAM WITH ECC DESCRIPTION FEATURES The I S S I IS61/64WV12816EDBLL is a high-speed, High-speed access time: 8, 10 ns 2,097,152-bit static RAMs organized as 131,072 words Low Active Power: 85 mW (typical) by 16 bits. It is fabricated using ISSI s high-performance Low Standby Power: 7 mW (typical) CMOS technology. This highly reliable process coupled CMOS standby with innovative 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 Data control for upper and lower bytes Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Industrial and Automotive temperature support Byte (LB) access. Lead-free available Error Detection and Error Correction The IS61/64WV12816EDBLL is packaged in the JEDEC standard 44-pin TSOP-II and 48-pin Mini BGA (6mm x 8mm).
