IS41C16256C
IS41LV16256C
256Kx16
4Mb DRAM WITH EDO PAGE MODE
JANUARY 2013
FEATURES

3.3V ± 10% (IS41LV16256C)
• Byte Write and Byte Read operation via two CAS
• Industrial Temperature Range -40°C to +85°C
DESCRIPTION
The IS41C16256C and IS41LV16256C are 262,144 x 16-bit
high-performance CMOS Dynamic Random Access Memo-
ries. Both products offer accelerated cycle access EDO
Page Mode. EDO Page Mode allows 512 random accesses
within a single row with access cycle time as short as 14ns
per 16-bit word. It is asynchronous, as it does not require a
clock signal input to synchronize commands and I/O.
These features make the IS41C/LV16256C ideally suited for
high band-width graphics, digital signal processing, high-
performance computing systems, and peripheral applications
that run without a clock to synchronize with the DRAM.
The IS41C/LV16256C is packaged in 40-pin TSOP
(Type II).
