SE717M-LF SE717M-
SCALER
Function Besides the ADC, LVDS, and scaling part, an MCU is embedded as well. All of them are integrated into one chip. Stores the MCU program embedded in the scaler. It is of a flash type and rewritable. Stores the OSD and various timing values. An IC that receives DC voltage inputs. It is used in circuits that stabilize the DC voltage.

Panel LVDS signal Key input Crystal
SE717M-LF (Scaler) Embeded MCU
Function: Transmits the LVDS signals obtained by scaling the received analog or digital inputs to fit the panel resolution. Since the MCU Core is embedded, it performs the existing Micom function but uses external memory as it has no internal memory.
MX25L1005MC (Flash Memory) Function: Saves the MCU code (Hex) data
SDR
I2C
24C08 (NVRAM) Function: Saves the timing value for each OSD and mode.
Analog Signal
Function Ass'y Function: Transmits the voltage value input when pressing a key.
