descriptions below.
In addition to the Read, Write and Erase Modes, the TC58FVM6(T/B)5B features many functions including block protection and
10.1. Read Mode
Software Reset Command releases The ID Read Mode, releases the lock state when an automatic operation ends abnormally,
and sets the device to Read Mode. Hardware Reset terminates operation of the device and resets it to Read Mode. When
reading data without changing the address immediately after power-on, the host should input Hardware Reset or change CE
from H to L.

current to flow. 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.
The device is automatically set to Read Mode immediately after power-on or on completion of an automatic operation. The
ID Read Mode is used to read the device maker code and device code. The mode is useful in that it allows EPROM
Access time in ID Read Mode is the same as that in Read Mode. For a list of the codes, please refer to the ID Code Table.
ID read can be executed in two ways, as follows:
TC58FVM6(T/B)5B has two ways to put the device into Standby Mode. In Standby Mode, DQ is put into the High-Impedance

To read an ID code, the bank address as well as the ID read address must be specified (with
maker code is output from address BK + 00; the device code is output from address BK + 01. From other banks, data is
output from the memory cells. Inputting a Reset command releases ID Read Mode and returns the device to Read Mode.
Mainly EPROM programmers use this method. Applying V
