FEATURES
DESCRIPTION
• TTL compatible inputs and outputs; tristate I/O
The ISSI IS41C16100 and IS41LV16100 are 1,048,576 x 16-bit
high-performance CMOS Dynamic Random Access Memories.
ThesedevicesofferanacceleratedcycleaccesscalledEDOPage
Mode. EDO Page Mode allows 1,024 random accesses within a
singlerowwithaccesscycletimeasshortas20nsper16-bitword.
The Byte Write control, of upper and lower byte, makes the
IS41C16100idealforusein16-bitand32-bitwidedatabussystems.
• Refresh Interval:
— Auto refresh Mode: 1,024 cycles /16 ms
—
RAS-Only, CAS-before-RAS (CBR), and Hidden
— Self refresh Mode - 1,024 cycles / 128ms
• JEDEC standard pinout
ThesefeaturesmaketheIS41C16100andIS41LV16100ideallysuited
for high-bandwidth graphics, digital signal processing, high-
performancecomputingsystems,andperipheralapplications.
• Single power supply:
— 5V 10ꢀ (IS41C16100)
— 3.3V 10ꢀ (IS41LV16100)
