Description
8Kbit dual-port asynchronous SRAM memory IC. Provides 1K x 8-bit parallel access. Packaged in 64-TQFP (14x14mm). Obsolete status, new original stock available (961 pcs). Made by Renesas.
Specifications
Memory size is 8Kbit (1,024 locations x 8 bits each). Parallel interface. Access time and write cycle time are 55 nanoseconds. Operates at supply voltage from 4.5V to 5.5V. Operates in ambient temperature range 0°C to 70°C. Requires surface-mount assembly with 64-TQFP package.
Device Structure
Dual port, asynchronous SRAM. Allows simultaneous access to memory from two separate ports without bus contention. Volatile memory technology, which means data is lost when power is removed.
Performance Characteristics
Fast access and write speeds—both 55ns. Robust for standard commercial temperature range (0°C to 70°C). Supports high data throughput for parallel bus applications. Capable of full-speed concurrent read/write operations.
Application Environments
Ideal for high-speed buffer memories, data-sharing between two processors, communication equipment, networking, and multi-processor systems where simultaneous memory access is needed. Used in various computing and industrial control systems.
Selection Guidelines
Choose if you need a dual-port SRAM with moderate memory size (8Kbit), standard speed (55ns), and parallel interface. Check that 4.5~5.5V supply and 64-TQFP package suit your design. Consider alternative options if lead-free (RoHS compliant) components are required due to this model being non-compliant.
Usage Considerations
This part is obsolete; consider long-term procurement risks. It is not RoHS-compliant so it’s not suitable for all applications, especially in regions with lead restrictions. Sensitive to moisture (MSL 3: 168 hours floor life), handle carefully during assembly. Not for use where wide supply voltage or extended temperature range is required.
Potential Equivalent/Replacement Models
