About Asynchronous SRAM

Asynchronous Static Random-Access Memory (SRAM) provides instant non-sequential data access without clock synchronization, offering deterministic latency for real-time systems. Unlike DRAM, it retains data without refresh cycles, reducing controller complexity and power overhead.

These memories excel in applications requiring rapid read/write operations and low-latency response, such as processor cache, communication buffers, and high-speed data acquisition. Their simplicity, speed, and noise immunity make asynchronous SRAM fundamental in embedded designs where timing precision is critical.

Frequently Asked Questions

Q: Does this SRAM require external refresh circuitry?
A: No – asynchronous SRAM maintains data without refresh cycles, simplifying system design.

Q: Is the 3.3V nominal voltage compatible with 5V TTL logic?
A: Yes, the 2.4V-3.6V operating range supports 3.3V systems while accepting TTL-level inputs.

Q: Can I use this in automotive temperature environments?
A: With its -40°C to 85°C industrial rating, it’s suitable for extended temperature applications but not AEC-Q100 automotive certified.

Q: How does asynchronous SRAM differ from synchronous types?
A: Asynchronous models operate without clock signals for immediate data access, while synchronous SRAM (SSRAM) uses clocked interfaces for burst transfers.

Q: What is the standby current consumption?
A: Refer to the ISSI datasheet for detailed power specifications – contact PCX for technical documentation.

Q: Are legacy replacements available for obsolete SRAMs?
A: ISSI specializes in long-lifecycle industrial memory. PCX can source compatible alternatives for discontinued parts.
