3.3 Notes on use
3.3.6 Notes on built-in PROM
(1) Programming adapter
To write or read data into/from the internal PROM, use the dedicated programming adapter and general-purpose
PROM programmer as shown in Table 3.3.1.

(2) Write and read
In PROM mode, operation is the same as that of the M5M27C256AK, but programming conditions of PROM
programmer are not set automatically because there are no internal device ID codes.
Accurately set the following conditions for data write/read. Take care not to apply 21 V to Vpp pin (is also used as
the CNVSS pin), or the product may be permanently damaged.
q Programming voltage : 12.5 V
q Setting of programming adapter switch : refer to table 3.3.2
q Setting of PROM programmer address : refer to table 3.3.3
