PROM VERSION
19.2 EPROM mode
19.2 EPROM mode
The built-in PROM version has the following two modes :
19–4
19.2.1 Write method
There are 2 types of the EPROM mode: 1M mode and 256K mode.
256K mode is recommended to write data deeply for the one time PROM version of which internal PROM
size is 32 Kbytes or less. 1M mode is recommended for the EPROM version owing to its write velocity
faster than 256K mode. It is because to write and erase is repeated for the EPROM version. However, the
M37702E2AFS and M37702E4AFS cannot use 1M mode.
Additionally, use 1M mode to write and read in the built-in PROM version of which PROM size is 32 Kbytes
or more.
Normal operating mode
EPROM mode
This mode has the same function as the mask ROM version.
The built-in PROM can be programmed and read in this mode. The PROM version enters this mode when
“L” level is input to the RESET pin
