Read Sequence
The device is selected by pulling CS low. The 8-bit
READ instruction is transmitted to the 25LC512 fol-
lowed by the 16-bit address. After the correct READ
instruction and address are sent, the data stored in the
memory at the selected address is shifted out on the
SO pin. The data stored in the memory at the next
address can be read sequentially by continuing to

16-bit Address
provide clock pulses. The internal Address Pointer is
automatically incremented to the next higher address
after each byte of data is shifted out. When the highest
address is reached (FFFFh), the address counter rolls
over to address 0000h allowing the read cycle to be
continued
terminated by raising the CS pin (Figure 2-1).
