IS61WV10248EDBLL IS64WV10248EDBLL 1M x 8 HIGH-SPEED ASYNCHRONOUS CMOS STATIC RAM WITH ECC FEATURES • High-speed access times: 8, 10, 20 ns • High-performance, low-power CMOS process • Multiple center power and ground pins for greater noise immunity • Easy memory expansion with CE and OE options • CE power-down • Fully static operation: no clock or refresh required • TTL compatible inputs and outputs • Packages available: – 48-ball miniBGA (6mm x 8mm) – 44-pin TSOP (Type II) • Industrial and Automotive Temperature Support • Lead-free available FEBRUARY 2013 DESCRIPTION The ISSI IS61/64WV10248EDBLL are very high-speed, low power, 1M-word by 8-bit CMOS static RAM. The IS61/64WV10248EDBLL are fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher 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. The IS61/64WV10248EDBLL operate from a single power supply and all inputs are TTL-compatible. The IS61/64WV10248EDBLL are available in 48 ball mini BGA (6mm x 8mm) and 44-pin TSOP (Type II) packages.
