IS62/65WV20488EALL IS62/65WV20488EBLL JANUARY 2015 2Mx8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM FEATURES DESCRIPTION High-speed access time: 45ns, 55ns The ISSI IS62WV20488EALL/BLL and CMOS low power operation IS65WV20488EALL/BLL are high-speed, 16M bit static 30 mW (typical) operating RAMs organized as 2M words by 8 bits. It is fabricated using 12 W (typical) CMOS standby ISSI s high-performance CMOS technology. This highly TTL compatible interface levels reliable process coupled with innovative circuit design Single power supply techniques, yields high-performance and low power 1.65V1.98V Vdd (62/65WV20488EALL) consumption devices. 2.2V--3.6V Vdd (62/65WV20488EBLL) When is HIGH (deselected) or when CS2 is LOW Fully static operation: no clock or refresh (deselected), the device assumes a standby mode at which required o o the power dissipation can be reduced down with CMOS input Industrial (-40 C to +85 C) and Automotive o o levels. (-40 C to +125 C) temperature support Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable controls both writing and reading of the memory. The IS62WV20488EALL/BLL and IS65WV20488EALL/BLL are packaged in the JEDEC standard 48-pin mini BGA (6mm x 8mm). BLOCK DIAGRAM Copyright 2014 Integrated Silicon Solution, Inc. All rights reserved.
