Family Overview
The GSQ8662Q08/09/18/36E are built in compliance with
the SigmaQuad-II SRAM pinout standard for Separate I/O
synchronous SRAMs. They are 75,497,472-bit (72Mb)
SRAMs. The GSQ8662Q08/09/18/36E SigmaQuad SRAMs
are just one element in a family of low power, low voltage
HSTL I/O SRAMs designed to operate at the speeds needed to
implement economical high performance networking systems.
Clocking and Addressing Schemes
The GSQ8662Q08/09/18/36E SigmaQuad-II SRAMs are
synchronous devices. They employ two input register clock
inputs, K and K. K and K are independent single-ended clock
inputs, not differential inputs to a single differential clock input
buffer. The device also allows the user to manipulate the
output register clock inputs quasi independently with the C and
C clock inputs. C and C are also independent single-ended
clock inputs, not differential inputs. If the C clocks are tied
high, the K clocks are routed internally to fire the output
registers instead.
Because Separate I/O SigmaQuad-II B2
RAMs always transfer
data in two packets, A0 is internally set to 0 for the first read or
write transfer, and automatically incremented by 1 for the next
transfer. Because the LSB is tied off internally, the address
field of a SigmaQuad-II B2
RAM is always one address pin
less than the advertised index depth (e.g., the 4M x 18 has a
2048K addressable index).
