Functional Description
The CY7C1516JV18, CY7C1527JV18, CY7C1518JV18, and
CY7C1520JV18 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 CY7C1516JV18
and two 9-bit words in the case of CY7C1527JV18 that burst
sequentially into or out of the device. The burst counter always
starts with a “0” internally in the case of CY7C1516JV18 and
CY7C1527JV18. On CY7C1518JV18 and CY7C1520JV18, the
burst counter takes in the least significant bit of the external
address and bursts two 18-bit words in the case of
CY7C1518JV18 and two 36-bit words in the case of
CY7C1520JV18 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.
