TW8845AT-LB1-GET

Overview

The TW8845AT-LB1-GET is an LCD video processor manufactured by Renesas Electronics Corporation, designed for video display applications. It integrates a built-in decoder supporting NTSC, PAL, and SECAM standards with automatic format detection. The device features LVDS and TTL inputs, an on-screen display (OSD) engine, a timing controller (TCON), and LVDS/MIPI interfaces. It operates within a temperature range of -40 to +105°C and utilizes a 156-pin LQFP package with dimensions of 20.0 x 14.0 x 1.40 mm and a 0.4 mm pitch.

Feature Summary

• Supports analog video decoding for NTSC, PAL, and SECAM with adaptive 2D comb filtering and automatic gain control.
• Handles digital inputs including BT.656, BT.601, BT.1120, and YCbCr/RGB up to 1080p resolution.
• Integrates a programmable TCON supporting single or dual channel LVDS panels up to 1920x1080 resolution.
• Includes font-based OSD with SPI Flash and EEPROM interface support for fast boot initialization.

Applications

• Video displays
• Surround view systems
• AR HUD video output expansion

Procurement Notes

Verify the specific suffix GET indicates reel packaging versus GE tray packaging when ordering. Confirm moisture sensitivity level MSL 3 requirements are met for storage and handling. Ensure compatibility with I2C control interfaces and check for any recent product change notices regarding label updates or manufacturing location changes before finalizing procurement plans.

Selection Notes

Select this component for designs requiring integrated analog-to-digital conversion and panel driving capabilities. Consider its support for multiple input formats and built-in image enhancement features. Evaluate the 156-pin LQFP footprint against available board space. Verify that the operating temperature range meets the environmental constraints of the target application.

Part Context

This part belongs to the TW8844/TW8845 family of LCD video processors from Renesas Electronics. It serves as a central processing unit for converting various video signals into formats suitable for TFT panels. The series is noted for integrating decoding, scaling, and display driving functions into a single chip to reduce system complexity.

Replacement Considerations

The TW8847 is listed as a substitute option, though it carries a Not Recommended for New Designs status. Verify functional equivalence and availability before considering replacement strategies for existing designs.
