2.
Operation cannot be guaranteed when the number of writes exceeds 20 times. In the case of the
μ
PD78F4216A and 78F4216AY with K standard, operation cannot be guaranteed when the number of
writes exceeds 5 times.

Cautions 1. If writing is not successful in write operation, execute the program command again, and
execute the verify command to confirm the normal completion of the write operation.

2. Handshake mode is supported by the following products.
μ
PD78F4216A, 78F4216AY: Other than I, K, E standard
μ
PD78F4218A, 78F4218AY: Other than I standard
Remark
The fifth alphabetic character from the left in the lot number indicates the standard of the product. After
executing the program command, execute the verify command to confirm the normal completion of the
write operation.
Handshake mode is the CSI write mode that uses P24.
