Manufacturer Part Number

7130SA55PFI

Description

IC SRAM with 8Kbit storage. Dual Port, Asynchronous type. Organized as 1K x 8 bits, providing high-speed parallel data access. Surface mount in a 64-pin TQFP package (14x14 mm). Access time and write cycle time both at 55ns allow fast read/write operations. Specifically designed for applications needing simultaneous access to memory from two buses.

Specifications

Memory type is volatile SRAM. Memory format is Dual Port, Asynchronous. Memory size is 8Kbit, organized as 1K words of 8 bits each. Parallel interface enables easy integration into digital systems. Supply voltage range from 4.5V to 5.5V. Operating temperature range from -40°C to +85°C. Packaging type is 64-LQFP, MSL 3 (168 hours floor life), RoHS non-compliant. ECCN EAR99, HTSUS 8542.32.0041.

Device Structure

Device uses Dual Port SRAM architecture, which supports two independent access ports for simultaneous operations. 64-pin plastic TQFP package allows compact surface mounting. Each port can read or write memory independently, supporting parallel processing and reducing bottlenecks.

Performance Characteristics

55ns access and write times enable fast memory transactions. Capable of operating over industrial temperature range from -40°C to 85°C. Designed to support high-speed and low-latency memory-intensive applications. Stable performance under recommended supply voltage (4.5V~5.5V).

Application Environments

Suitable for industrial equipment, communication devices, networking hardware, and embedded systems requiring dual port memory for concurrent access. Also used in designs needing reliable asynchronous SRAM with fast cycle times, such as buffers, caches, and shared memory spaces between processors.

Selection Guidelines

Use this device when simultaneous memory access from two buses is required. Choose for applications needing fast parallel SRAM with medium capacity. Verify supply voltage compatibility (4.5V-5.5V). Make sure the system can handle the parallel interface and the 64-pin TQFP footprint. Pay attention to its obsolete status if planning long-term production.

Usage Considerations

Device is discontinued and is classified as obsolete. Not RoHS compliant, so unsuitable for some new designs or regulated industries. Moisture sensitivity level is MSL 3; must be mounted within 168 hours of opening packaging. Ensure system compatibility with 64-TQFP (14x14 mm) layout.

Potential Equivalent/Replacement Models

Equivalent or alternative models available: 7130LA25PFGI is suggested as a substitute. Customers should always confirm compatibility in terms of speed, voltage, package, and pinout.
