Teardown: Mustek Gsmart mini 2

Miniature 1.3 MP camera with built-in lithium battery.
Captured images are stored in RAM (16 MB), not in Flash.
VC373A = Octal D-type transparent latch with 5-volt tolerant inputs/outputs 3-State 

The SPCA504A is a digital camera processor chip that provides a complete solution for dual mode camera
applications. This chip integrates image sensor interface, digital video input interface, color image processor,
storage media controller, JPEG image compression engine, USB interface, and a built-in micro-controller. The
SPCA504A supports both CCD and CMOS image sensors up to 1.1M and 2.0M pixels respectively. It is
designed to fulfill all the requirements for the dual mode camera applications. The SPCA504A camera processor
chip includes not only the latest technology, but also the full services and support of Sunplus.

The main functions of the SPCA504A includes:
● DSC mode : capture one frame each time
● Video clip mode : capture a video with frame rate 15~30 frames/sec
● PC-camera mode : 30 frames/sec for CIF size, 20 frames/sec for VGA size

Under the copper shielding foil: Winbond W39L512P-90, 512 kbit, 3.3V FLASH memory.
Battery: SYN382035A, 23x20x4mm according to http://www.jing-yang.com.tw.

Optical part is very simple - just few lenses, manually operated focus.
Optical sensor is surprisingly large for such small camera one could easily mistake for a toy, overall image quality is little disappointing though. I was hoping especially for useful PC camera mode (it also does not depend on internal battery that is in poor condition 9 years after manufacturing), but it is usable only in good light.
