(1) The F-ZTAT and mask ROM versions have been confirmed as fully meeting the reference
(2) On-chip power supply step-down circuit
values for electrical characteristics shown in this manual. However, actual performance
figures, operating margins, noise margins, and other properties may vary due to differences in
the manufacturing process, on-chip ROM, layout patterns, etc.
When system evaluation testing is carried out using the F-ZTAT version, the same evaluation
tests should also be conducted for the mask ROM version when changing over to that version.
The H8S/2138 F-ZTAT does not incorporate an internal power supply step-down circuit.
When changing over to F-ZTAT versions or mask ROM versions incorporating an internal
step-down circuit, the V
Therefore, note that the circuit patterns differ between these two types of products.
3. Block erase time (shows the total period for which the E-bit in FLMCR1 is set. It does
4. Maximum programming time (tP (max))
5. Number of times when the wait time after P-bit setting (z) = 200 µs.
6. Maximum erase time (tE (max))
7. Number of times when the wait time after E-bit setting (z) = 10 ms.
Usage Note
The number of writes should be set according to the actual set value of (z) to allow

The number of erases should be set according to the actual set value of (z) to allow
erasing within the maximum erase time (tE (max)).
