Ready/Busy (RB)
The Ready/Busy output, RB, is an open-drain output that can be used to identify if the Program/ Erase/ Read (PER)
Controller is currently active.
When Ready/Busy is Low, V
OL
, a read, program or erase operation is in progress. When the operation completes
Ready/Busy goes High, V
OH
.
The use of an open-drain output allows the Ready/ Busy pins from several memories to be connected to a single pull-
up resistor. A Low will then indicate that one, or more, of the memories is busy.
Refer to the Ready/Busy Signal Electrical Characteristics section for details on how to calculate the value of the pull-up
resistor.
V
CC
Supply Voltage
V
CC
provides the power supply to the internal core of the memory device. It is the main power supply for all operations
(read,program and erase).
An internal voltage detector disables all functions whenever V
CC
is below 2.5V (for 3V devices) or 1.5V (for 1.8V
devices) to protect the device from any involuntary program/erase during power-transitions.
Each device in a system should have V
CC
decoupled with a 0.1uF capacitor. The PCB track widths should be sufficient
to carry the required program and erase currents
V
SS
Ground
Ground, V
SS
, is the reference for the power supply. It must be connected to the system ground.
BUS OPERATIONS
There are six standard bus operations that control the memory. Each of these is described in this section, see Tables 2,
Bus Operations, for a summary.
Command Input
Command Input bus operations are used to give commands to the memory. Command are accepted when Chip Enable
is Low, Command Latch Enable is High, Address Latch Enable is Low and Read Enable is High. They are latched on the
rising edge of the Write Enable signal.
Only I/O
0
to I/O
7
are used to input commands. See Figure 21 and Table 14 for details of the timings requirements.
Address Input
Address Input bus operations are used to input the memory address. Four bus cycles are required to input the
addresses for the 512Mb devices (refer to Tables 3 and 4, Address Insertion). The addresses are accepted when Chip
Enable is Low, Address Latch Enable is High, Command Latch Enable is Low and Read Enable is High. They are latched
on the rising edge of the Write Enable signal. Only I/O
0
to I/O
7
are used to input addresses.
See Figure 22 and Table 14 for details of the timings requirements.
Data Input
Data Input bus operations are used to input the data to be programmed.
Data is accepted only when Chip Enable is Low, Address Latch Enable is Low, Command Latch Enable is Low and Read
Enable is High. The data is latched on the rising edge of the Write Enable signal. The data is input sequentially using
the Write Enable signal.
See Figure 23 and Tables 14 and 15 for details of the timings requirements.
