S34ML02G100TFI000 Pin Description

I/O0 - I/O7 (×8) / I/O8 - I/O15 (×16): Inputs/Outputs. The I/O pins are used for command input, address input, data input, and data output. The I/O pins float to High-Z when the device is deselected or the outputs are disabled.

CLE: Command Latch Enable. This input activates the latching of the I/O inputs inside the Command Register on the rising edge of Write Enable (WE#).

ALE: Address Latch Enable. This input activates the latching of the I/O inputs inside the Address Register on the rising edge of Write Enable (WE#).

CE#: Chip Enable. This input controls the selection of the device. When the device is not busy CE# low selects the memory.

WE#: Write Enable. This input latches Command, Address and Data. The I/O inputs are latched on the rising edge of WE#.

RE#: Read Enable. The RE# input is the serial data-out control, and when active drives the data onto the I/O bus. Data is valid tREA after the falling edge of RE# which also increments the internal column address counter by one.

WP#: Write Protect. The WP# pin, when low, provides hardware protection against undesired data modification (program / erase).

R/B#: Ready Busy. The Ready/Busy output is an Open Drain pin that signals the state of the memory.

VCC: Supply Voltage. The VCC supplies the power for all the operations (Read, Program, Erase). An internal lock circuit prevents the insertion of Commands when VCC is less than VLKO.

VSS: Ground.

NC: Not Connected.
