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 CY7C1516V18 and two 9-bit words in the case of CY7C1527V18 that burst sequentially into or out of the device. The burst counter always starts with a “0” internally in the case of CY7C1516V18 and CY7C1527V18. On CY7C1518V18 and CY7C1520V18, the burst counter takes in the least significant bit of the external address and bursts two 18-bit words in the case of CY7C1518V18 and two 36-bit words in the case of CY7C1520V18 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 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.

Functional Description

The CY7C1516V18, CY7C1527V18, CY7C1518V18, and CY7C1520V18 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 CY7C1516V18 and two 9-bit words in the case of CY7C1527V18 that burst sequentially into or out of the device. The burst counter always starts with a “0” internally in the case of CY7C1516V18 and CY7C1527V18. On CY7C1518V18 and CY7C1520V18, the burst counter takes in the least significant bit of the external address and bursts two 18-bit words in the case of CY7C1518V18 and two 36-bit words in the case of CY7C1520V18 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 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.
