IS62WV6416ALL IS62WV6416BLL 64K x 16 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM JANUARY 2008 FEATURES DESCRIPTION * High-speed access time: 45ns, 55ns The ISSI IS62WV6416ALL/ IS62WV6416BLL are highspeed, 1M bit static RAMs organized as 64K words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields highperformance and low power consumption devices. * CMOS low power operation: 30 mW (typical) operating 15 W (typical) CMOS standby When CS1 is HIGH (deselected) or when CS2 is LOW (deselected) or when CS1 is LOW, CS2 is HIGH and both LB and UB are HIGH, the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. * TTL compatible interface levels * Single power supply 1.7V--2.2V VDD (62WV6416ALL) 2.5V--3.6V VDD (62WV6416BLL) Easy memory expansion is provided by using Chip Enable and Output Enable inputs. 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. * Fully static operation: no clock or refresh required * Three state outputs * Data control for upper and lower bytes The IS62WV6416ALL and IS62WV6416BLL are packaged in the JEDEC standard 48-pin mini BGA (6mm x 8mm) and 44-Pin TSOP (TYPE II). * Industrial temperature available * 2CS Option Available * Lead-free available FUNCTIONAL BLOCK DIAGRAM A0-A15 DECODER 64K x 16 MEMORY ARRAY VDD GND I/O0-I/O7 Lower Byte I/O DATA CIRCUIT I/O8-I/O15 Upper Byte CS2 CS1 OE WE UB LB COLUMN I/O CONTROL CIRCUIT Copyright (c) 2008 Integrated Silicon Solution, Inc.
