IS61WV25632BLL-10BLI

Memory IC Overview

The IS61WV25632BLL-10BLI is an asynchronous static random-access memory (SRAM) manufactured by ISSI. It provides a total storage capacity of 8 Mbit, organized as 256K words by 32 bits. The device features a parallel interface with a maximum access time of 10 ns. It operates within a supply voltage range of 2.4 V to 3.6 V and supports surface mount installation in a 90-TFBGA package measuring 8x13 mm. The component is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Asynchronous parallel interface for direct data access without clock synchronization
• High-speed 10 ns access time for rapid read operations
• Wide single-voltage supply compatibility ranging from 2.4 V to 3.6 V
• Industrial temperature rating ensuring reliable performance in extreme environments

Memory IC Applications

• Embedded systems requiring fast local data buffering
• Industrial control units needing reliable volatile memory
• Telecommunications equipment utilizing high-speed data processing
• Automotive electronics operating under variable thermal conditions

Memory IC Procurement Notes

Verify the specific suffix BLI confirms the 90-TFBGA package and lead-free status. Confirm RoHS compliance requirements match project specifications. Check for moisture sensitivity level constraints during storage and handling. Ensure the 10 ns speed grade aligns with system timing budgets. Validate that the 256K x 32 organization fits the memory map architecture.

Memory IC Selection Notes

Select this component when a 32-bit wide data path is required for high-throughput applications. The 8 Mbit density offers a balance between capacity and pin count compared to narrower alternatives. The TFBGA package suits space-constrained designs needing robust surface mounting. Consider the 10 ns speed if synchronous alternatives are unsuitable for the control logic.

Memory IC Part Context

This part belongs to the IS61WV series of high-speed asynchronous SRAMs from ISSI. The WV designation typically indicates wide voltage operation. The BLL suffix often denotes specific package and temperature grades within the family. This series complements other densities like 16Mbit or 4Mbit variants for scalable memory solutions.

Memory IC Replacement Considerations

Direct substitutes include IS61WV25632BLL-10BLI-TR for tape-and-reel packaging. Verify pinout compatibility before replacing with other 90-TFBGA SRAMs. Cross-reference electrical specs with similar ISSI models like IS61WV25632BLL-10TLI if package changes are acceptable.
