SN54F32AJ Datasheet first five address bits are reserved for larger density devices (see Notes on page 8), the next 10 address bits (PA9-PAO) specify the page address, and the next nine address bits (BA8-BAO) specify the starting byte address within the page. The 32 don't care bits which follow the 24 address bits are sent to initialize the read operation. Fol- lowing the 32 don't care bits, additional pulses on SCK result in serial data being output on the SO (serial output) pin. The CS pin must remain low during the loading of the opcode, the address bits, and the reading of data. When the end of a page in main memory is reached during a main memory page read, the device will continue reading at the beginning of the same page. A low to high transition on the CS pin will terminate the read operation and tri-state the SO pin. SN54F32AJ Price Control Signal Layout There are no time-critical control signals on the GigaPHY-SD device. However, it is important to route control lines to the chips in such a way as to avoid crosstalk and noise injection. Data Bus Layout SN54F32AJ on stock
The Data Output pin is a tri-state TTL compatible output. It is normally in a high impedance state unless a READ or an ENABLE BUSY instruction is executed. Following the completion ofa 16-bitor 8-bit data stream, the output will return to the high impedance state. During a pro- gram/erase cycle, if the ENABLE BUSY instruction has been previously executed, the output will stay LOW while the device is BUSY, and it will be set HIGH when the program/erase cycle is completed. DO will stay HIGH until the completion of the next instruction's op- code and,ifthe nextinstruction is a READ, DO willoutput the appropriate data at the end of the instruction. If the ENABLE BUSY instruction has not been previously executed, DO will stayin a high impedance state. DO will
