IS61WV10248EDBLL IS64WV10248EDBLL 1M x 8 HIGH-SPEED ASYNCHRONOUS APRIL 2020 CMOS STATIC RAM WITH ECC FEATURES DESCRIPTION High-speed access times: 8, 10, 20 ns The ISSI IS61/64WV10248EDBLL are very high-speed, High-performance, low-power CMOS process low power, 1M-word by 8-bit CMOS static RAM. The Multiple center power and ground pins for IS61/64WV10248EDBLL are fabricated using ISSI s high-performance CMOS technology. This highly reli- greater noise immunity able process coupled with innovative circuit design Easy memory expansion with CE and OE options techniques, yields higher performance and low power CE power-down consumption devices. Fully static operation: no clock or refresh When CE is HIGH (deselected), the device assumes required a standby mode at which the power dissipation can be TTL compatible inputs and outputs reduced down with CMOS input levels. Packages available: The IS61/64WV10248EDBLL operate from a single 48-ball miniBGA (6mm x 8mm) power supply and all inputs are TTL-compatible. 44-pin TSOP (Type II) The IS61/64WV10248EDBLL are available in 48 ball Industrial and Automotive Temperature Support mini BGA (6mm x 8mm) and 44-pin TSOP (Type II) Lead-free available packages.
