3.2 PROM Mode
(1)
Mode Setting and Function
PROM mode is set by setting the
to the “L” level.
RESET
and CLK pins
The programming and verification for the internal PROM is
achieved by using a general EPROM programmer with the
adaptor socket. The device selection (ROM Type)
should be “27256” with following conditions.
size: 256Kbit (32K x 8bit) VPP: 12.5V TPW: 1ms
Figure 3.2 shows the setting of pins in PROM mode.

Programming Flow Chart
The programming mode is set by applying 12.5V (pro-
gramming voltage) to the VPP pin when the following pins
are set as follows,
(Vcc
: 6.0V)
*These conditions can be
(
RESET
: “L” level) obtained by using adaptor
(CLK
: “L” level) socket.
After the address and data have been fixed, a data on
the Data Bus is programmed when the CE pin is set to
“Low” (1ms plus is required).
General Programming procedure of an EPROM programmer
is as follows,
Write a data to a specified address for 1ms.
Verify the data. If the read-out data does not match
the expected data, another writing is performed until
the correct data is written (Max. 25 times).
After the correct data is written, an additional writing is
performed by using three times longer programming
pulse width (1ms x programming times), or using three
times more programming pulse number. Then, verify
the data and increment the address.
The verification for all data is done under the condition
of Vpp = Vcc = 5V after all data were written.
Figure 3.3 shows the programming flow chart.
