IS62WV20488ALL IS62WV20488BLL 2M x 8 HIGH-SPEED LOW POWER August 2016 CMOS STATIC RAM FEATURES DESCRIPTION High-speed access times: The ISSI IS62WV20488ALL/BLL is a high-speed, 25, 35 ns low power, 2M-word by 8-bit CMOS static RAM. The High-performance, low-power CMOS process IS62WV20488ALL/BLL is fabricated using ISSI s high- performance CMOS technology. This highly reliable pro- Multiple center power and ground pins for greater cess coupled with innovative circuit design techniques, noise immunity yields higher performance and low power consumption Fully static operation: no clock or refresh devices. required When CS1 is HIGH (deselected) or when CS2 is LOW TTL compatible inputs and outputs (deselected), the device assumes a standby mode at Single power supply which the power dissipation can be reduced down with Vdd 1.65V to 2.2V (IS62WV20488ALL) CMOS input levels. speed = 35ns for Vcc = 1.65V to 2.2V The IS62WV20488ALL/BLL operates from a single power supply and all inputs are TTL-compatible. Vdd 2.4V to 3.6V (IS62WV20488BLL) speed = 25ns for Vcc = 2.4V to 3.6V The IS62WV20488ALL/BLL is available in 48 ball mini BGA and 44-pin TSOP (Type II) packages. Packages available: 48-ball miniBGA (9mm x 11mm) 44-pin TSOP (Type II) Industrial Temperature Support Lead-free available FUNCTIONAL BLOCK DIAGRAM 2M X 8 A0-A20 DECODER MEMORY ARRAY VDD GND I/O COLUMN I/O I/O0-I/O7 DATA CIRCUIT CS2 CS1 CONTROL CIRCUIT OE WE Copyright 2016 Integrated Silicon Solution, Inc.
