FUNCTION IN EPROM MODE
1M mode (equivalent to the M5M27C101K)
Reading
__
To read the EPROM, set the CE and OE pins to a “L” level. Input the
address of the data (A0 – A16) to be read, and the data will be output
to the I/O pins D0 – D7. The data I/O pins will be floating when either
__
the CE or OE pins are in the “H” state.
Programming
Programming must be performed in 8 bits by a byte program. To
__
program to the EPROM, set the CE pin to a “L” level and the OE pin to
a “H” level. The CPU will enter the programming mode when 12.5 V
is applied to the VPP pin. The address to be programmed to is selected
with pins A0 – A16, and the data to be programmed is input to pins D0
___
– D7. Set the PGM pin to a “L” level to being programming.
Erasing
To erase data on this chip, use an ultraviolet light source with a 2537
Angstrom wave length. The minimum radiation power necessary for
erasing is 15 J/cm2.
Programming operation
To program the M37735EHBXXXFP, first set VCC = 6 V, VPP = 12.5
V, and set the address to 0100016. Apply a 0.2 ms programming
pulse, check that the data can be read, and if it cannot be read OK,
repeat the procedure, applying a 0.2 ms programming pulse and
checking that the data can be read until it can be read OK. Record
the accumulated number of pulse applied (X) before the data can be
read OK, and then write the data again, applying a further once this
number of pulses (0.2 ! X ms).
When this series of programming operations is complete, increment
the address, and continue to repeat the procedure above until the
last address has been reached.
Finally, when all addresses have been programmed, read with VCC =
VPP = 5 V (or VCC = VPP = 5.5 V).
