IS62C1024AL IS65C1024AL 128K x 8 LOW POWER CMOS DECEMBER 2017 STATIC RAM 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, Industr ial, and Automotive tem- perature ranges available Standard Pin Configuration: 32-pin SOP/ 32-pin TSOP (Type 1) Lead free available FUNCTIONAL BLOCK DIAGRAM 128K x 8 A0-A16 DECODER MEMORY ARRAY VDD GND I/O COLUMN I/O I/O0-I/O7 DATA CIRCUIT CE1 CONTROL CE2 CIRCUIT OE WE Copyright 2017 Integrated Silicon Solution, Inc.
