IS62C10248AL IS65C10248AL 1Mx 8LOW VOLTAGE, ULTRALOWPOWERCMOSST ATICRAM PRELIMINARYINFORMA TION DECEMBER2010 FEATURES DESCRIPTION The I S S I IS62C10248AL/IS65C10248AL are high- High-speed access time: 45ns, 55ns speed, 8M bit static RAMs organized as 1M words by CMOS low power operation 8 bits. It is fabricated using I S S I s high-performance CMOS technology. This highly reliable process coupled 36 mW (typical) operating with innovative circuit design techniques, yields high- 12 W (typical) CMOS standby performance and low power consumption devices. TTL compatible interface levels When CS1 is HIGH (deselected) or when CS2 is LOW (deselected), the device assumes a standby mode at Single power supply which the power dissipation can be reduced down with CMOS input levels. 4.5V--5.5V Vdd Easy memory expansion is provided by using Chip Enable Three state outputs and Output Enable inputs. The active LOW Write Enable o o Automotive temperature (-40 C to +125 C) (WE) controls both writing and reading of the memory. The IS62C10248AL and IS65C10248AL are packaged in Lead-free available the JEDEC standard 48-pin mini BGA (9mm x 11mm) and 44-Pin TSOP (TYPE II).
