Overview
IS42/45R86400D/16320D/32160D IS42/45S86400D/16320D/32160D 16Mx32, 32Mx16, 64Mx8 MAY 2015 512Mb SDRAM device OVERVIEW FEATURES • Clock frequency: 200, 166, 143 MHz • Fully synchronous; all signals referenced to a positive clock edge • Internal bank for hiding row access/precharge • Power supply: Vdd/Vddq = 2.
3V-3.
6V IS42/45SxxxxxD - Vdd/Vddq = 3.
3V IS42/45RxxxxxD - Vdd/Vddq = 2.
5 • LVTTL interface • Programmable burst length – (1, 2, 4, 8, full page) • Programmable burst sequence: Sequential/Interleave ISSI's 512Mb Synchronous DRAM achieves high-speed data transfer using pipeline architecture.
All inputs and outputs signals refer to the rising edge of the clock input.
The 512Mb SDRAM is organized as follows.
