OPERATION MODES
protection and data polling. When incorporating the device into a deign, please refer to the timing charts and
flowcharts in combination with the description below.
In addition to the Read, Write and Erase Modes, the TC58FVT160/B160A features many functions including block
READ MODE
high-speed random access as asynchronous ROM.
operation. A software reset releases ID Read Mode and the lock state which the device enters if automatic
operation ends abnormally, and sets the device to Read Mode. A hardware reset terminates operation of the
device and resets it to Read Mode. When reading data without changing the address immediately after power-on,
either input a hardware Reset or change CE from H to L.
ID Read Mode
EPROM programmers to identify the device type automatically.
(1) Applying V
(2) Input command sequence
Standby Mode
(1) Control using CE and RESET
(2) Control using RESET only
Auto-Sleep Mode
device will automatically enter Sleep Mode and the current will be reduced to the standby current (I
Because the output data is latched, data is output in Sleep Mode. When the address is changed, Sleep Mode is
automatically released, and data from the new address is output.
To read data from the memory cell array, set the device to Read Mode. In Read Mode the device can perform
The device is automatically set to Read Mode immediately after power-on or on completion of automatic
ID Read Mode is used to read the device maker code and device code. The mode is useful in that it allows
ID read can be executed in two ways, as follows:
There are two ways to put the device into Standby Mode.
This function suppresses power dissipation during reading. If the address input does not change for 150 ns, the

This method is used mainly by EPROM programmers. Applying V
Inputting an ID Read command sets to ID Read Mode. The maker code is output from address 00; the
Access time in ID Read Mode is the same as that in Read Mode. For a list of the codes, please refer to the
