PROM Programming

The PROM mode write/verify specifications are the same as those of the standard EPROM

HN27C101. However, because the page program format is not supported, do not set the PROM

writer to the page programming mode. PROM writers that only support page programming mode

cannot be used. When selecting a PROM writer, confirm that it supports the byte-by-byte high-

speed, high-reliability programming format.

21.3.1

Programming Mode Selection

There are two on-chip PROM programming modes: write and verify (reads and confirms written

data). The mode is selected by using the pins (table 21.2).
