IC41C4100 I C 4 1 LV 4 1 0 0
1M x 4 (4-MBIT) DYNAMIC RAM WITH EDO PAGE MODE
FEATURES
Extended Data-Out (EDO) Page Mode access cycle TTL compatible inputs and outputs; tristate I/O Refresh Interval: 1024 cycles /16 ms Refresh Mode: RAS-Only, CAS-before-RAS (CBR), Hidden · Single power supply: 5V ± 10% (IC41C4100) 3.3V ± 10% (IC41LV4100) · Industrail Temperature Range -40oC to 85oC · · · ·
DESCRIPTION The ICSI IC41C4100 and IC41LV4100 is a 1,048,576 x 4-bit
high-performance CMOS Dynamic Random Access Memories. The IC41C4100 offer an accelerated cycle access called EDO Page Mode. EDO Page Mode allows 1024 random accesses within a single row with access cycle time as short as 12 ns per 4-bit word. These features make the IC41C4100and IC41LV4100 ideally suited for, digital signal processing, high-performance audio systems, and peripheral applications. The IC41C4100 is packaged in a 20-pin 300mil SOJ and 300mil TSOP-2.
