IS62C5128BL, IS65C5128BL 512K x 8 HIGH-SPEED CMOS STATIC RAM FEATURES • High-speed access time: 45ns • Low Active Power: 50 mW (typical) • Low Standby Power: 10 mW (typical) CMOS standby • TTL compatible interface levels • Single 5V ± 10% power supply • Fully static operation: no clock or refresh required • Available in 32-pin sTSOP-I, 32-pin SOP and 32-pin TSOP-II packages • Commercial, Industrial and Automotive temperature ranges available • Lead-free available JULY 2011 DESCRIPTION The ISSI IS62C5128BL and IS65C5128BL are high-speed, 4,194,304-bit static RAMs organized as 524,288 words by 8 bits. They are fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields access times as fast as 45ns with low power consumption. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The IS62C5128BL and IS65C5128BL are packaged in the JEDEC standard 32-pin sTSOP-I, 32-pin SOP and 32-pin TSOP-II packages FUNCTIONAL BLOCK DIAGRAM A0-A18 DECODER 512K X 8 MEMORY ARRAY I/O DATA CIRCUIT COLUMN I/O VDD GND I/O0-I/O7 CE OE CONTROL CIRCUIT WE Copyright © 2010 Integrated Silicon Solution, Inc.
