2 / 21 page IC41C8512 IC41LV8512 2 Integrated Circuit Solution Inc. DR029-0A 09/28/2001 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% (IC41C8512) 3.3V ± 10% (IC41LV8512) • Industrail Temperature Range -40oC to 85oC DESCRIPTION The ICSI IC41C8512 and IC41LV8512 is a 524,288 x 8-bit high- performance CMOS Dynamic Random Access Memories. The IC41C8512 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 8-bit word. These features make the IC41C8512and IC41LV8512 ideally suited for, digital signal processing, high-performance audio systems, and peripheral applications. The IC41C8512 is packaged in a 28-pin 400mil SOJ and 400mil TSOP-2. 512K x 8 (4-MBIT) DYNAMIC RAM WITH EDO PAGE MODE KEY TIMING PARAMETERS Parameter -35 -50 -60 Unit Max. RAS Access Time (tRAC) 355060 ns Max. CAS Access Time (tCAC) 101415 ns Max. Column Address Access Time (tAA) 182530 ns Min. EDO Page Mode Cycle Time (tPC) 122025 ns Min.
