Product Overview
The AL440B-24-PBF is a cost-effective uni-directional single-port synchronous video FIFO memory developed by AverLogic Technologies. Equipped with integrated auto address pointer logic to eliminate external address decoding circuits, it supports stable sequential pixel read/write operation for video stream buffering, frame synchronization, time base correction and scan interpolation tasks. This 4M-bit CMOS memory chip adopts lead-free 44-Pin TSSOP packaging, delivering low-latency performance up to 40MHz, acting as a compact, low-cost alternative to bulky external SDRAM video buffers.
Core Advantages
Single-Port Synchronous Video FIFO Architecture
Built-in unified synchronous clock control with 8-bit unidirectional parallel data bus, realizing reliable pixel data caching for different video clock domains without complex arbitration peripheral circuits.
Simplified Video Buffer Peripheral Design
Eliminates redundant memory row/column address calculation, refresh circuit and extra external controller required by DRAM solutions. Data reads and writes sequentially via simple control signals, effectively reducing PCB layout area and overall BOM cost.
Low-Latency 40MHz High-Speed Operation
Supports maximum 40MHz synchronous clock frequency to meet real-time frame buffering demand of standard-definition video devices, with ultra-short access delay to avoid frame loss and image distortion.
Integrated Multi-Level Data Flow Protection Flags
On-chip programmable Empty, Full and Half-Full status flags provide real-time data volume monitoring, preventing data overflow or loss during continuous video stream transmission.
Low-Power Lead-Free Compact Packaging
Adopts low power consumption CMOS process and 44-Pin TSSOP lead-free package, compatible with standard SMT mass production, suitable for surveillance, broadcast and portable imaging equipment.

Frequently Asked Questions
Q1: Is AL440B-24-PBF 100% genuine original stock?
A: All stocked AL440B-24-PBF are brand new factory-original chips from AverLogic. Every batch passes strict quality inspection and packed with factory standard anti-static shielding packaging.
Q2: Why choose AL440B-24-PBF FIFO instead of traditional SDRAM/DRAM for video processing?
A: Ordinary DRAM/SRAM requires extra external controllers for address generation, bus arbitration and refresh cycles. AL440B integrates internal address sequencing logic, supporting direct pixel stream read/write without complicated peripheral circuits or delay.
Q3: What does the “PBF” suffix stand for?
A: PBF means Pb-Free lead-free manufacturing, fully compliant with EU RoHS, REACH and global hazardous substance control standards.
Q4: How to get official datasheet and bulk quotation?
A: Fill out the Quick Inquiry form on this page with your order quantity and technical demands. Our technical team will send complete datasheets and competitive bulk prices within 24 hours.
Q5: What is the maximum operating clock frequency of AL440B-24-PBF?
A: This video FIFO supports up to 40MHz synchronous clock, fully suitable for standard definition real-time video processing equipment.
