Key input
MX25LV512
(Flash Memory)
Function: Stores the
MCU code (Hex) data.
24C02
(DDC - Digital)
Function: Stores the
digital EDID data
Function: Transfers the inputs entered by the user to the Micom using
Location
Scaler Besides the ADC, LVDS, and scaling part, an MCU is embedded as well. All of
IC200 them are integrated into one chip.
Flash
Stores the MCU program embedded in the scaler. It is of a flash type and
Memory
rewritable.
IC201
IC203 Stores the OSD and various timing values.
IC202 The memory to which DIGITAL DDC data is input
An IC that receives DC voltage inputs. It is used in circuits that stabilize the DC
Regulator
voltage.
SE758MRH-LF
Embeded MCU
Function: Receives analog/digital inputs and
scales to and outputs LVDS signals which
are fit to the panel resolution.
It works the same way as an old Micom
because it has an embedded MCU core.
But it uses external memory because it has no
ISP MCU memory.
One EEPROM is embedded to store DDC data.
Digital Signal
