TP6820

The TP6820 is designed as one kind of digital camera solution,when collocated with PAS009 CMOS image sensor made by pixart,provides a total solution for a QQVGA resolution RS232 interface digital camera.It can act as a digital still camera when stand-alone mode,it also can act as a live view camera when connecting to PC through RS232 interface.By adding a SRAM with 128 kx 8 bits capacity,it can store twelve pictures while snapshot button is pressed.When connecting to PC,user can get the images from this storage through RS232 with "show me cam" software application.

Features of the TP6820 are:(1)supports PAS 009 sensor interface;(2)support image processor;(3)support image snapshot function;(4)support auto power saving mode with port wake up function;(5)support RS232 interface,up to 115200bps speed;(6)support indicator LED;(7)support warning buzzer;(8)support H/W erase picture function;(9)embedded an 8-bits micto controller;(10)embedded 128 bytes of RAM;(11)embedded 4K bytes of ROM;(12)support wide supply voltage range:from 3.0V to 3.6V;(13)operating frequency:11.0592MHz;(14)support SRAM interface with 128 Kbytes capacity.

The absolute maximum ratings of the TP6820 are:(1)operating temperature:0 to 70;(2)storage temperature:-65 to +150;(3)voltage on any pin:-0.5 to +7 V;(4)power dissipation:0.2 W.Note:stresses above those listed may cause permanent damage to the device.Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
