Description
8Kbit Dual Port, Asynchronous SRAM memory IC. Enables parallel access and operation from two different ports. Package type is 64-TQFP (14x14mm). Obsolete status. Used for fast memory access and concurrent multi-device data sharing.
Specifications
Memory type: Volatile SRAM
Technology: Dual port, asynchronous
Memory size: 8 Kbit (8,192 bits)
Memory organization: 1K x 8 (1,024 words of 8 bits each)
Access time: 100 ns
Write cycle time (word, page): 100 ns
Voltage supply: 4.5V to 5.5V
Operating temperature: 0°C to 70°C (commercial grade)
Interface: Parallel
Mounting: Surface mount
Package: 64-LQFP or 64-TQFP (14mm x 14mm)
Moisture Sensitivity Level (MSL): 3 (168 hours)
Device Structure
Uses dual independent data ports for simultaneous access
Parallel interface for fast read/write operations
No integrated error correction
Composed of SRAM memory arrays and interface control logic
Encapsulated with 64-QFP plastic package suitable for SMD assembly
Leads arranged in a quad flat package for high-density PCB integration
Performance Characteristics
Fast data access (100ns access time)
Simultaneous, conflict-free operations at both ports
Stable operation from 4.5V to 5.5V
Does not retain data after power-off (volatile)
Reliable under standard commercial temperature range
Low-latency for critical data buffering and exchange tasks
Application Environments
Widely used in DSP, communication systems, data routers, switches
Suited for dual-processor or multi-master bus architectures
Used for shared memory storage, FIFO buffering, multi-user data access
Not recommended for new design due to obsolete status
Recommended for environments needing high-speed shared SRAM, but not for severe temperature/industrial conditions
RoHS non-compliant, not suitable for eco-restricted manufacturing
Selection Guidelines
Best for designs requiring dual-port, asynchronous access to small fast memory
Choose when parallel interface and 5V operation are required
Verify operating voltage and temperature range for compatibility
Check long-term supply needs due to obsolete status
Consider package requirement: 64-QFP surface-mount type
Check RoHS and REACH requirements for your application
Review access/write cycle timing for system speed matching
Usage Considerations
Power loss erases memory contents
Observe maximum voltage and temperature limits for reliable operation
Handle as Moisture Sensitivity Level 3 device; proper bake/dry procedures before reflow soldering
Not suitable for automotive, high-reliability, or extended temperature environments
Plan for EOL (end of life) and sourcing strategy
Be aware of non-compliance with RoHS environmental standards
Potential Equivalent/Replacement Models
Direct substitute model available: 7140LA25PFG
For other options or alternative equivalents, consult the Ariat-Tech sales team for detailed support and replacement suggestions tailored to your application needs.
If no suitable substitute is found, consider custom solutions or redesign using currently available dual-port SRAMs from other manufacturers.
