IC41C8513 and IC41LV8513
512K x 8 (4-MBIT) DYNAMIC RAM
WITH FAST PAGE MODE
FEATURES
DESCRIPTION
• Fast Page Mode Access Cycle
• TTL compatible inputs and outputs
• Refresh Interval:
The ICSI 8513 Series is a 524,288 x 8-bit high-performance
CMOS Dynamic Random Access Memory. The Fast Page
Mode allows 1,024 random accesses within a single row with
access cycle time as short as 12 ns per 8-bit word.
-- 1,024 cycles/16 ms
• Refresh Mode: RAS-Only,
CAS-before-RAS (CBR), and Hidden
• JEDEC standard pinout
• Single power supply:
5V ± 10% or 3.3V ± 10%
• Byte Write and Byte Read operation via
two CAS
These features make the 8513 Series ideally suited for high-
bandwidthgraphics, digitalsignalprocessing, high-performance
computing systems, and peripheral applications.
The 8513 Series is packaged in a 28-pin 400mil SOJ and a 28
pin TSOP-2
