Operation
The S1C60R08 has two operation modes,
• Programming mode: Load the data from the Serial EEPROM
• Normal mode:
Work as if the mask ROM type
The following describes how to operate the S1C60R08.
1) Make an application software.
2) Convert the software to the Serial EEPROM format with winedg in the S1C60R08 package.
3) Write the program which is converted to the Serial EEPROM format to the Serial EEPROM.
4) Set up the S1C60R08, the Serial EEPROM and the other peripheral components on the user target
application. (The example is described in "BASIC EXTERNAL CONNECTION DIAGRAM".)
5) The application power on.
6) The S1C60R08 enters to the Programming mode, and starts data loading from the Serial EEPROM to the
built-in ROM emulator automatically. In the loading, internal circuit is kept as system reset condition ex-
cept the Programmer. And data error checking is done at the same time.
7) If the data error happens, the ERROUT pin goes HIGH level and data loading is terminated.
8) If the data has loaded without any error, the S1C60R08 enters to the Normal mode automatically. Then
the CPU read the ROM emulator data as the instruction and start to run as if the mask ROM type.
9) If you want to re-load the data, input a HIGH pulse to the OTPRST pin. Then the S1C60R08 enters to
Programming mode and starts re-loading.

SUMMARY OF NOTES
q
Target Type for S1C60N08 Series
The S1C60N08 has 3 types (S1C60N08, S1C60A08 and S1C60L08).
In these models, the S1C60R08 supports the following 2 types as the ROM emulator model.
S1C60N08 V
DD
= 3.0 V (Typ.), OSC1
S1C60A08 V
DD
= 3.0 V (Typ.), OSC1/OSC3
Refer the "S1C60N08/60R08 Technical Manual".
q
Mask/Segment Option
The S1C60R08 can load ROM emulator data. But cannot load the mask option and segment option. Therefore
customer must make the function option data and segment option data by the S1C60R08 development tool at
first. Then send the data to SEIKO EPSON and order the mask. SEIKO EPSON makes the S1C60R08 with a
customized option according to this request.
q
Serial EEPROM
The external Serial EEPROM is necessary for programming the ROM emulator data, and this component
is recommended.
Recommended component: AK6010A/12A (AKM)
M24C64/32 (SGS-THOMSON)
BR24C64 (ROHM)
24AA64 (Microchip)
Note: Use larger EEPROM than program memory size.
