EPROM CELL STRUCTURE
OTP(One Time Programmable) has been implemented on the S6B0756. The EPROM stores the offset volume for
VOUT calibration after the device has been assembled and calibrated on a LCD module. For OTP programming,
OTPD pin and OTPG pin are used. Those pins should be made available on the module glass
The OTP block of the S6B0756 consists of 6 bits. 1 bit is used for OTP mode protection bit(OPRT), and 5 bits are
used for VOUT calibration(OV4~OV0).

Description -.
OPRT : The Offset Volume(OV) can be written to EPROM only when OPRT bit = ‘ 0
OV4~OV0 : The OV is used for calibrating the VOUT voltage as an offset to the
EV register value.
VOUT CALIBRATION FLOW
VOUT may be calibrated with OTP in the following order.(ex : EX = 32, OV=-3)
