TW8806-DPB2-GR (NON-EPI)

Video Processing Overview

The TW8806-DPB2-GR (NON-EPI) is an LCD flat panel TV and PC monitor controller manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates a high-performance NTSC/PAL/SECAM video decoder, analog RGB inputs, DACs, and a timing controller (T-CON). The device supports TFT panel resolutions up to 1280x768 with one pixel per clock format. It features three 9-bit ADCs for YPbPr/RGB component input and accepts 24-bit digital RGB or 8/16/24-bit YCbCr inputs. The core operates at 1.8 V while I/O operates at 3.3 V.

Video Processing Procurement Notes

Verify the specific suffix DPB2-GR against current manufacturer documentation to confirm pinout and electrical characteristics. Confirm availability status as this component may be discontinued or subject to limited supply constraints. Ensure compatibility with existing system power requirements of 1.8V core and 3.3V I/O before integration.

Video Processing Selection Notes

Select this component for applications requiring integrated TV decoding and TFT panel driving in a compact form factor. It is suitable for designs needing direct connection to analog PC graphics cards or DTV sources via YCbCr inputs. Consider the 128-pin PQFP package size when designing PCB layouts for portable or automotive electronics.

Video Processing Part Context

This part belongs to the TW8806 series of LCD display processors designed for mixed-signal integration. Originally developed by Techwell and acquired by Intersil, it serves as a cost-effective solution for standalone LCD displays. The NON-EPI designation typically indicates non-epitaxial substrate processing, though specific manufacturing details should be verified in official datasheets.

Video Processing Replacement Considerations

The datasheet explicitly recommends the TW8835 as a replacement part. Note that the TW8835 is not pin-compatible with the TW8806. Design modifications will be required if substituting this component with the recommended alternative.
