Programming and verification should be carried out using the same specifications as for the
standard HN27C101 EPROM.
However, do not set the PROM programmer to page mode does not support page programming. A
PROM programmer that only supports page programming cannot be used. When choosing a
PROM programmer, check that it supports high-speed programming in byte units. Always set
addresses within the range H'00000 to H'1FFFF.
19.5.2
An efficient, high-speed programming procedure can be used to program and verify PROM data.
This procedure writes data quickly without subjecting the chip to voltage stress or sacrificing data
reliability. It leaves the data H'FF in unused addresses. Figure 19.4 shows the basic high-speed
programming flowchart. Tables 19.6 and 19.7 list the electrical characteristics of the chip during
programming. Figure 19.5 shows a timing chart.
