minimum glue logic. Maximum access delay from clock rise is
6.5 ns (133-MHz version). A 2-bit on-chip counter captures the
first address in a burst and increments the address automati-
cally for the rest of the burst access. All synchronous inputs
are gated by registers controlled by a positive-edge-triggered
Clock Input (CLK). The synchronous inputs include all
addresses, all data inputs, address-pipelining Chip Enable
( CE
Control inputs ( ADSC , ADSP , and ADV ), Write Enables
( BW
i nputs include the Output Enable ( OE ) and the ZZ pin .
The CY7C1325F allows either interleaved or linear burst
sequences, selected by the MODE input pin. A HIGH selects
an interleaved burst sequence, while a LOW selects a linear
burst sequence. Burst accesses can be initiated with the
Processor Address Strobe (ADSP) or the cache Controller
Address Strobe (ADSC) inputs.
Addresses and chip enables are registered at rising edge of
clock when either Address Strobe Processor ( ADSP ) or
Address Strobe Controller ( ADSC ) are active. Subsequent
burst addresses can be internally generated as controlled by
the Advance pin ( ADV ).
The CY7C1325F operates from a +3.3V core power supply
while all outputs may operate with either a +2.5 or +3.3V
supply. All inputs and
