FEATURES DESCRIPTION
The ISSI IS62C1024AL/IS65C1024AL is a low power,
High-speed access time: 35, 45 ns
131,072-word by 8-bit CMOS static RAM. It is fabricated
Low active power :100 mW (typical)
using high-performance CMOS technology. This highly
Low standby power :20 W (typical) CMOS
reliable process coupled with innovative circuit design
standby
techniques, yields higher performance and low power
consumption devices.
Output Enable (OE) and two Chip Enable
(CE1 and CE2) inputs for ease in applications
When CE1 is HIGH or CE2 is LOW (deselected), the device
assumes a standby mode at which the power dissipation
Fully static operation: no clock or refresh
can be reduced by using CMOS input levels.
required
TTL compatible inputs and outputs Easy memory expansion is provided by using two Chip
Enable inputs, CE1 and CE2. The active LOW Write Enable
Single 5V (10%) power supply
(WE) controls both writing and reading of the memory.
Commercial, Industrial, and Automotive tem-
perature ranges available
Standard Pin Configuration:
32-pin SOP/ 32-pinTSOP (Type 1)
Lead free available
