BU6521KV-E2

Overview

The BU6521KV-E2 is a video encoder manufactured by ROHM Semiconductor, designed for converting digital video signals. It operates within a supply voltage range of 1.4 V to 1.6 V and draws a typical operating current of 40 mA. The device supports an I2C interface for control and is housed in a 48-pin VQFP package suitable for surface mount installation. It handles input resolutions up to 720 x 480 pixels with an 8-bit resolution capability. The component functions reliably across an extended temperature range from -40°C to +85°C, with a maximum power dissipation of 900 mW.

Feature Summary

• Integrates video encoding functionality for standard definition formats
• Supports I2C serial interface for register configuration and control
• Operates on low voltage single power supply
• Includes built-in LVDS transmitter capabilities

Applications

• Video signal processing in consumer electronics
• Embedded systems requiring SD video encoding

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate that stock is currently unavailable or discontinued. Buyers should verify final availability through authorized distributors and consider alternative sourcing strategies due to the discontinuation status.

Selection Notes

Designers must account for the low supply voltage requirement of 1.4 V to 1.6 V when selecting power management components. The 48-pin VQFP package requires specific PCB footprint considerations. Since the part is discontinued, engineers should evaluate replacement options early in the design phase to ensure long-term supply chain stability.

Part Context

The BU6521KV-E2 belongs to the BU6521KV series of video ICs produced by ROHM Semiconductor. This series focuses on providing integrated video encoding solutions for compact electronic applications. The E2 suffix typically denotes specific manufacturing or compliance variations within the product line.

Replacement Considerations

As this part is discontinued, engineers should consult ROHM's official documentation for recommended substitute models. Cross-referencing pin compatibility and electrical specifications with newer generation video encoders is essential for successful migration.
