Flash Programming Voltage Output (Flash Vcc Out) - Epson S5U1C33001H1400 Manual

5.3.3

Flash programming voltage output (FLASH VCC OUT)

Some target S1C processors have internal flash memory that can supply the voltage (7 V)
necessary for flash programming from the S5U1C33001H. The maximum current that can
be provided in this way is 200 mA.
To use this output, set the DIP SW8 to ON and connect the power supply from the target
system to the FLASH VCC OUT pin. Note that setting the DIPS SW8 to ON results in a
constant output of 7 V from the FLASH VCC OUT pin regardless of the operation of the
RESET/START switch.
Note: Refer to the relevant technical manual to determine if the target S1C processor can

use this output. (To prevent overvoltage-induced damage to the S1C processor, avoid
using this output if no applicable instructions are provided in the technical manual.)
