IS41C16100S
IS41LV16100S
1M x 16 (16-MBIT) DYNAMIC RAM
WITH EDO PAGE MODE
FEATURES
DESCRIPTION
The ICSI IS41C16100S and IS41LV16100S are 1,048,576 x
• Extended Data-Out (EDO) Page Mode access cycle
• TTL compatible inputs and outputs; tristate I/O
• Refresh Interval:
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
• Single power supply:
5V ± 10% (IS41C16100S)
3.3V ± 10% (IS41LV16100S)
• Byte Write and Byte Read operation via two CAS
16-bit high-performance CMOS Dynamic Random Access
Memories. These devices offer an accelerated cycle access
called EDO Page Mode. EDO Page Mode allows 1,024 random accesses within a single row with access cycle time as
short as 20 ns per 16-bit word. The Byte Write control, of upper
and lower byte, makes the IS41C16100S ideal for use in
16-, 32-bit wide data bus systems.
These features make the IS41C16100Sand IS41LV16100S
ideally suited for high-bandwidth graphics, digital signal
processing, high-performance computing systems, and
peripheral applications.
• Industrail Temperature Range -40°C to 85°C
The IS41C16100S and IS41LV16100S are packaged in a
42-pin 400mil SOJ and 400mil 50- (44-) pin TSOP-2.
