| CY7C1317CV18, CY7C1917CV18 CY7C1319CV18, CY7C1321CV18 18-Mbit DDR-II SRAM 4-Word Burst Architecture Functional Description • 18-Mbit density 2M x 8, 2M x 9, 1M x 18, 512K x 36 • 300 MHz clock for high bandwidth • 4-word burst for reducing address bus frequency • Double Data Rate DDR interfaces data transferred at 600 MHz at 300 MHz • Two input clocks K and K for precise DDR timing SRAM uses rising edges only • Two input clocks for output data C and C to minimize clock skew and flight time mismatches • Echo clocks CQ and CQ simplify data capture in high-speed systems • Synchronous internally self-timed writes • DDR-II operates with cycle read latency when the DLL is enabled • Operates similar to a DDR-I device with 1 cycle read latency in DLL off mode • 1.8V core power supply with HSTL inputs and outputs • Variable drive HSTL output buffers • Expanded HSTL output voltage • Available in 165-Ball FBGA package 13 x 15 x mm • Offered in both Pb-free and non Pb-free packages • JTAG compatible test access port • Delay Lock Loop DLL for accurate data placement The CY7C1317CV18, CY7C1917CV18, CY7C1319CV18, and CY7C1321CV18 are 1.8V Synchronous Pipelined SRAMs equipped with DDR-II architecture. The DDR-II consists of an SRAM core with advanced synchronous peripheral circuitry and a two-bit burst counter. Addresses for read and write are latched on alternate rising edges of the input K clock. Write data is registered on the rising edges of both K and K. Read data is driven on the rising edges of C and C if provided, or on the rising edge of K and K if C/C are not provided. Each address location is associated with four 8-bit words in the case of CY7C1317CV18 and four 9-bit words in the case of CY7C1917CV18 that burst sequentially into or out of the device. The burst counter always starts with a ‘00’ internally in the case of CY7C1317CV18 and CY7C1917CV18. For CY7C1319CV18 and CY7C1321CV18, the burst counter takes in the least two significant bits of the external address and bursts four 18-bit words in the case of CY7C1319CV18, and four 36-bit words in the case of CY7C1321CV18, sequentially into or out of the device. Asynchronous inputs include an output impedance matching input ZQ . Synchronous data outputs Q, sharing the same physical pins as the data inputs, D are tightly matched to the two output echo clocks CQ/CQ, eliminating the need to capture data separately from each individual DDR SRAM in the system design. Output data clocks C/C enable maximum system clocking and data synchronization flexibility. All synchronous inputs pass through input registers controlled by the K or K input clocks. All data outputs pass through output registers controlled by the C or C or K or K in a single clock domain input clocks. Writes are conducted with on-chip synchronous self-timed write circuitry.
