WITH EDO PAGE MODE
NOVEMBER 2000
FEATURES
DESCRIPTION
• Extended Data-Out (EDO) Page Mode access cycle
TheISSI IS41C82002andIS41LV82002are2,097,152x8-bit
high-performance CMOS Dynamic Random Access
Memory. These devices offer an accelarated cycle ac-
cess called EDO Page Mode. EDO Page Mode allows
2,048 random accesses within a single row with access
cycle time as short as 20 ns per 4-bit word.
• TTL compatible inputs and outputs
• Refresh Interval:
-- 2,048 cycles/32 ms
• Refresh Mode: RAS-Only,
CAS-before-RAS (CBR), and Hidden
• Single power supply:
These features make the IS41C82002 and IS41LV82002
ideally suited for high-bandwidth graphics, digital signal
processing, high-performance computing systems, and
peripheral applications.
5V 10ꢀ or 3.3V 10ꢀ
• Byte Write and Byte Read operation via two CAS
• Industrial temperature range -40°C to 85°C
TheIS41C82002andIS41LV82002arepackagedin28-pin
300-mil SOJ and 28-pin TSOP (Type II) with JEDEC
standard pinouts.
