IS62C1024-55QI中文资料矽成半导体数据手册PDF规格书

DESCRIPTION

The ISSI IS62C1024 is a low power,131,072-word by 8-bit CMOS static RAM. It is fabricated using ISSIs high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields higher performance and low power consumption devices.

When CE1 is HIGH or CE2 is LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced by using CMOS input levels. Easy memory expansion is provided by using two Chip Enable inputs, CE1 and CE2. The active LOW Write Enable (WE) controls both writing and reading of the memory.

The IS62C1024 is available in 32-pin 525-mil plastic SOP and TSOP (type 1) packages.
