Flash Programming Voltage Output (Flash Vcc Out) - Epson S5U1C17001H2 User Manual

4.1.2.3

Flash programming voltage output (FLASH VCC OUT)

Depending on the Flash memory built into the target S1C processor, it may be necessary to supply the Flash
programming voltage to the V
supplying the Flash programming voltage from the FLASH VCC OUT pin. The voltage can be supplied as
described below.
When S1C17 processor is selected
Use in conjunction with S5U1C17001C (GNU17 v2.0.0 or later) outputs a variable voltage of 6.0 V to 8.0 V
(max. 100 mA).
For more details of the Flash programming voltage output method with the S1C17 processor selected, refer
to "5.4 Flash Programming Voltage Setting" or "6. Flash Programmer Mode."
When S1C33 processor is selected
Setting SW8 to "ON" outputs a fixed voltage of 7.0 V (max. 100 mA).
Setting SW8 to "ON", always outputs a voltage of 7 V voltage from the FLASH VCC OUT pin regardless
of whether the RESET/START switch is operated.
Note: Refer to the individual technical manual for each model to determine whether the Flash programming
voltage supply is required. Do not use this voltage unless mentioned in the technical manual. Otherwise,
there is a risk of damaging the S1C processor due to overvoltage.
