ꢀEATURES
DESCRIPTION
ꢀAST Page Mode access cycle
TTL compatible inputs and outputs
Refresh Interval:
The ICSI 82052 Series is a 2,097,152 x 8-bit high-performance
CMOS Dynamic Random Access Memory. The &ast Page
Mode allows 2,048 random accesses within a single row with
access cycle time as short as 20 ns per 8-bit word.
-- 2,048 cycles/32 ms
These features make the 82052 Series ideally suited for high-
bandwidthgraphics, digitalsignalprocessing, high-performance
computing systems, and peripheral applications.
Refresh Mode: RAS-Only,
CAS-before-RAS (CBR), and Hidden
JEDEC standard pinout
Single power supply:
The 82052 Series is packaged in a 28-pin 300mil SOJ and a 28
pin TSOP-2
5V±10% or 3.3V ± 10%
