The specifications for writing and reading are identical to those for the standard HN27C101
EPROM. However, page programming is not supported, and so page programming mode must not
be set. A PROM programmer that only supports page programming mode cannot be used. When
selecting a PROM programmer, ensure that it supports high-speed, high-reliability byte-by-byte
programming. Also, be sure to specify addresses from H'0000 to H'EDFF.
6.3.1
An efficient, high-speed, high-reliability method is available for writing and verifying the PROM
data. This method achieves high speed without voltage stress on the device and without lowering
the reliability of written data. The basic flow of this high-speed, high-reliability programming
method is shown in figure 6-4.
