Description
Synchronous Load/Advance: Loads a new address into counter when
low. RAM uses internally generated burst addresses when high.
Clock: This signal registers the address, data in, and all control signals
except G and LBO.
Clock Enable: Disables the CK input when CKE is high.
Synchronous Data I/O: “x” refers to the byte being read or written
(byte a, b, c, d).

Input
Linear Burst Order Input: This pin must remain in steady state (this
signal not registered or latched). It must be tied high or low.
Low – linear burst counter.
High – interleaved burst counter.
Input Synchronous Address Inputs: These inputs are registered and must
meet setup and hold times.
Input
Synchronous Burst Address Inputs: The two LSB’s of the address field.
These pins must preset the burst address counter values. These inputs
are registered and must meet setup and hold times.
Input Synchronous Byte Write Inputs: Enables write to byte “x”
(byte a, b, c, d) in conjunction with SW. Has no effect on read cycles.
Input Synchronous Chip Enable: Active low to enable chip.
Input Synchronous Chip Enable: Active high for depth expansion.
Input Synchronous Chip Enable: Active low for depth expansion.
Input Synchronous Write: This signal writes only those bytes that have been
selected using the byte write SBx pins.
Supply Core Power Supply.
Supply I/O Power Supply.
Supply Ground.
NC
— No Connection: There is no connection to the chip.
