(1) Programming adapter
(2) Write and read
(3) Erasing
To write into or read from data the internal PROM, use the dedicated programming adapter and general-purpose
PROM programmer as shown in Table 3.1.1.
In PROM mode, operation is the same as that of the M5M27C101, but programming conditions of PROM
programmer are not set automatically because there are no built-in device ID codes.
Accurately set the following conditions for data write/read. Do not apply 21 V to the Vpp pin (is also used as port
