The specifications for writing and reading the on-chip PROM are identical to those for the
standard HN27C101 EPROM. Page programming is not supported, however. The PROM writer
must not be set to page mode. A PROM programmer that provides only page programming mode
cannot be used. When selecting a PROM programer, check that it supports a byte-by-byte high-
speed, high-reliability programming method. Be sure to set the address range to H'0000 to
H'EDFF.
6.5.1
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 6.8.
