IS65C256AL IS62C256AL 32K x 8 LOW POWER CMOS STATIC RAM www.DataSheet4U.com ISSI ® MARCH 2006 FEATURES • Access time: 25 ns, 45 ns • Low active power: 200 mW (typical) • Low standby power — 150 µW (typical) CMOS standby — 15 mW (typical) operating • Fully static operation: no clock or refresh required • TTL compatible inputs and outputs • Single 5V power supply • Lead-free available • Industrial and Automotive temperatures available DESCRIPTION The ISSI IS62C256AL/IS65C256AL is a low power, 32,768 word by 8-bit CMOS static RAM. It is fabricated using ISSI’s high-performance, low power CMOS technology. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down to 150 µW (typical) at CMOS input levels. Easy memory expansion is provided by using an active LOW Chip Select (CE) input and an active LOW Output Enable (OE) input. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS62C256AL/IS65C256AL is pin compatible with other 32Kx8 SRAMs in plastic SOP or TSOP (Type I) package.
