Memory IC datasheet and documents for IS62WV2568BLL-55TLI-TR
Memory IC Overview
The IS62WV2568BLL-55TLI-TR is a 2M-bit (256K x 8) asynchronous static RAM fabricated using high-performance CMOS technology. It operates within a voltage range of 2.5V to 3.6V and features a typical access time of 55ns. The device supports industrial temperature operation from -40°C to +85°C and utilizes a 32-pin TSOP Type I package. Key electrical characteristics include a maximum dynamic operating current of 35mA and a typical standby current of 10µA.
Memory IC Feature Summary
- Provides fully static operation without requiring clock signals or periodic refresh cycles.
- Features three-state outputs with TTL-compatible interface levels for versatile logic integration.
- Supports easy memory expansion through dedicated Chip Enable and Output Enable inputs.
Memory IC Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microprocessor architectures
- Industrial control system data storage
Memory IC Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm package type, lead-free status, and temperature grade. Ensure the supply voltage matches the BLL series requirements. Confirm moisture sensitivity handling procedures are followed during assembly due to surface mount construction.
Memory IC Selection Notes
Select this component when a 256K x 8 organization is required with 55ns access speed. It is suitable for designs needing low power consumption with a 2.5V to 3.6V supply rail. Consider the TSOP-32 footprint constraints and industrial temperature rating during PCB layout.
Memory IC Part Context
This part belongs to the IS62WV2568BLL family of low-voltage, ultra-low power CMOS SRAMs. The BLL designation indicates compatibility with 2.5V to 3.6V power supplies, distinguishing it from the ALL series which supports lower voltages. The family offers multiple speed grades and package options including TSOP and mini BGA.
Memory IC Replacement Considerations
Compatible substitutes include other 256K x 8 asynchronous SRAMs with similar 55ns access times and 3.3V operation. Verify pinout compatibility and voltage tolerances before substitution.
