rev 2.01 c328r jpeg camera module w/ uart interface general description the c328r is vga camera module performs as a jpeg compressed still camera and can be attached to a wireless or pda host. users can send out a snapshot command from the host in order to capture a full resolution single-frame still picture. the picture is then compressed by the jpeg engine and transferred to the host thru serial port. block diagram features z small in size, 20x28mm z vga resolution, down sample to qvga or cif z 3.3v operation z low power consumption 60ma z user friendly commands to control the module z uart interface of up to 115.2kbps z auto detect baud rate and make connection to the host z power saving mode z various lens options pin description pin description vcc power 3.3vdc txd data transmit (3.3v) rxd data receive (3.3v) gnd power ground connector specification: 2mm pitch, 4pin single row reference part no: suyin 190600 mating connector: suyin 140600 command summary detail command control, please refer to the user?s manual 1. initial to configure the image size, color type 2. get picture get picture type 3. snapshot set snap shot image type 4. set package size set the package size to transmit data from module to host 5. set baudrate change the baud rate 6. reset reset the whole syst em or reset the state machine 7. power off to enter sleep mode 8. data set the data type and length for transmitting data to host 9. sync sync signal to connect between host and module 10. ack command to indicate the communication success 11. nak command to indicate the communication fail with error code vga image sensor jpeg compression engine eeprom (program) vcc gnd txd rxd gnd rxd txd vcc bottom view
