NT68F62 Datasheet PDF – 8-Bit Microcontroller for Monitor
8-Bit Microcontroller for Monitor (32K Flash MTP Type)
NT68F62 overview
The NT68F62 is an 8-Bit Microcontroller for Monitor (32K Flash MTP Type) made by Novatek Microelectronics, supplied in a 40-pin P-DIP and 42-pin S-DIP Type package. This page brings together the NT68F62 pinout, with the full datasheet PDF to preview below or download.
The NT68F62 is a new generation of monitor mC for auto- sync and digital control applications. Particularly, this chip supports various functions to allow users to easily develop USB monitors. It contains the 6502 8-bit CPU core, 512 bytes of RAM for use as working RAM and as stack area, 32K bytes of Flash memory, 13-channels of 8-bit PWM D/A converters, 4-channel A/D converters for detection of keys which can save I/O pins, one 8-bit pre-loadable base timer, an internal Hsync and Vsync signals processor and a watch-dog timer, which prevents the system from abnormal operation and two IIC bus interfaces. The user can store EDID data in the 128 bytes of RAM for DDC1/2B, so that the user can reduce a dedicated EEPROM for EDID. The half frequency output function can save the external one- shot circuit. All of these designs are borne of our commitment to offer our user savings on component costs. The 42 pin S-DIP IC provides two additional I/O pins – port40 & port41, Part number NT68F62U represents the S- DIP IC. For future reference, port40 & port42 are only available for the 42 pin S-DIP IC.
