CY7C1316CV18 CY7C1916CV18 CY7C1318CV18 CY7C1320CV18 18-Mbit DDR-II SRAM 2-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 • 2-Word burst for reducing address bus frequency • Double Data Rate DDR interfaces data transferred at 600 MHz 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 like 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 lead-free and non lead-free packages • JTAG 1149.1-compatible test access port • Delay Lock Loop DLL for accurate data placement Configurations CY7C1316CV18 2M x 8 CY7C1916CV18 2M x 9 CY7C1318CV18 1M x 18 CY7C1320CV18 512K x 36 The CY7C1316CV18, CY7C1916CV18, CY7C1318CV18 and CY7C1320CV18 are 1.8V Synchronous Pipelined SRAM equipped with DDR-II architecture. The DDR-II consists of an SRAM core with advanced synchronous peripheral circuitry and a 1-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 two 8-bit words in the case of CY7C1316CV18 and two 9-bit words in the case of CY7C1916CV18 that burst sequentially into or out of the device. The burst counter always starts with a “0” internally in the case of CY7C1316CV18 and CY7C1916CV18. On CY7C1318CV18 and CY7C1320CV18, the burst counter takes in the least significant bit of the external address and bursts two 18-bit words in the case of CY7C1318CV18 and two 36-bit words in the case of CY7C1320CV18 sequentially into or out of the device. Asynchronous inputs include 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 for separately capturing data 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.
