18Mb Pipelined QDR II SRAM Burst of 2 IDT71P72804 IDT71P72604 18Mb Density 1Mx18, 512kx36 Separate, Independent Read and Write Data Ports - Supports concurrent transactions Dual Echo Clock Output 2-Word Burst on all SRAM accesses DDR Double Data Rate Multiplexed Address Bus - One Read and One Write request per clock cycle DDR Double Data Rate Data Buses - Two word burst data per clock on each port - Four word transfers per clock cycle 2 word bursts on 2 ports Depth expansion through Control Logic HSTL 1.5V inputs that can be scaled to receive signals from 1.4V to 1.9V. Scalable output drivers - Can drive HSTL, 1.8V TTL or any voltage level from 1.4V to 1.9V. - Output Impedance adjustable from 35 ohms to 70 ohms Commercial and Industrial Temperature Ranges 1.8V Core Voltage VDD 165-ball, 1.0mm pitch, 13mm x 15mm fBGA Package JTAG Interface The IDT QDRIITM Burst of two SRAMs are high-speed synchronous memories with independent, double-data-rate DDR , read and write data ports. This scheme allows simultaneous read and write access for the maximum device throughput, with two data items passed with each read or write. Four data word transfers occur per clock cycle, providing quad-data-rate QDR performance. Comparing this with standard SRAM common I/O CIO , single data rate SDR devices, a four to one increase in data access is achieved at equivalent clock speeds. Considering that QDRII allows clock speeds in excess of standard SRAM devices, the throughput can be increased well beyond four to one in most applications. Using independent ports for read and write data access, simplifies system design by eliminating the need for bi-directional buses. All buses associated with the QDRII are unidirectional and can be optimized for signal integrity at very high bus speeds. The QDRII has scalable output impedance on its data output bus and echo clocks, allowing the user to tune the bus for low noise and high performance. The QDRII has a single DDR address bus with multiplexed read and write addresses. All read addresses are received on the first half of the clock cycle and all write addresses are received on the second half of the clock cycle. The read and write enables are received on the first half of the clock cycle. The byte and nibble write signals are received on both halves of the clock cycle simultaneously with the data they are controlling on the data input bus.
