IC41C1665
IC41LV1665
64K x 16 (1-MBIT) DYNAMIC RAM
WITH FAST PAGE MODE
FEATURES
DESCRIPTION
• Fast access and cycle time
• TTL compatible inputs and outputs
• Refresh Interval: 256 cycles/4 ms
• Refresh Mode: RAS-Only, CAS-before-RAS
(CBR), Hidden
• JEDEC standard pinout
• Single power supply:
— 5V ± 10% (IC41C1665)
— 3.3V ± 10% (IC41LV1665)
The ICSI IC41C1665 and the IC41LV1665 are 65,536 x 16-
bit high-performance CMOS Dynamic Random Access
Memory. Fast Page Mode allows 256 random accesses
within a single row with access cycle time as short as 12 ns
per 16-bit word. The Byte Write control, of upper and lower
byte, makes these devices ideal for use in 16-, 32-bit wide
data bus systems.
These features make the IC41C1665 and the IC41LV1665
ideally suited for high band-width graphics, digital signal
processing, high-performance computing systems, and
peripheral applications.
• Byte Write and Byte Read operation via
two CAS
The IC41C1665 and the IC41LV1665 are packaged in a 40-
pin, 400mil SOJ and TSOP-2.
• Available in 40-pin SOJ and TSOP-2
