20.6.2 Bus timing and EPROM mode
The PROM versions shown in Table 20.6.2 have the different bus timing from other PROM versions, mask
ROM, external ROM versions. Additionally, they can use only 256K mode as the EPROM mode though its
PROM size is 32 Kbytes or less.
(1) Bus timing
(2) EPROM mode
The limits and formulas of the PROM versions having the peculiar bus timing which is different from
other PROM versions are shown in Table 20.6.2.
When the user is planning to use the product shown in Table 20.6.2 for evaluation or in early
production and replace it later with the mask ROM version, we recommend to use the substitute
shown in Table 20.6.3 for evaluation or in early production.
However, the substitute version has the higher frequency of external clock input. There are no
precaution about its operation.
The products shown in Table 20.6.2 can use only 256K mode as the EPROM mode. Do not use 1M
mode.
