I'm trying to identify this logo/part, I've searched combinations of the letters that appear on it as well as IC manufacturer logos and didn't have much luck. At one point I was pointed to a "display processor" site but I can't seem to find it again. Here is the image:


There is a USB port with the power pins running to this chip. I supplied 3.3V with my programmable power supply, it appears its is drawing about 300 mA. The display turns on, displays a lightning bolt graphic/animation, as if the battery is charging, and that's it.

Other info: A rather unique device was turned into lost and found and no one has claimed it, so it was turned over to the hardware lab to properly dispose of it--but I'm curious, what is it?! It is a device that has a lithium ion battery, some push buttons, a small speaker, a panel display (HYB070HD), and a 2Gb NXP RAM component. None of it is in an enclosure, rather its a circuit board glued to the back of the display with the push buttons dangling by wires soldered t other.

    \$\begingroup\$ It's a mailed video advertisement. I have one here that was programmed with a commercial for a projector company, and another that was programmed with several videos advertising a security camera company. I generally dismantle these kits and use the perfectly good components for other projects. \$\endgroup\$

This is a V100 chip from chinese IC company Actions Semiconductor.

The chip function is described in this press release:

The V100 is a versatile, all-in-one solution tailored for 3D movie watching applications. The V100 integrates a MIPS32 processor together with a compact integrated video engine, display subsystem and audio engine to deliver an immersive 3D video experience. It supports up to 1280x800@60fps LCD display and all standard video decoding playback capabilities which includes H.264 FHD 1080P@30fps video decoder. The V100 features DDR2/DDR1 DRAM, SPI NOR, NAND Flash Controller with max 40-bit ECC, integrated RGB and LVDS LCD interface, built-in stereo 20-bit DAC and 20mW power amplifier for headphones. The V100 offers rich interfaces such as USB 2.0, SDIO and integrates several regulators to maximize power efficiency and reduce residual heat.
