Frequently Asked Questions
What are the access time and memory density specifications of IS62LV256AL-45ULI?
The IS62LV256AL-45ULI is a 256K x 8-bit SRAM offering 2 Mbit total density with a maximum access time of 45 ns. This combination of density and speed makes it suitable for buffer memory, lookup tables, and working data storage in embedded microcontroller systems operating at bus speeds up to approximately 20 MHz.
How does IS62LV256AL-45ULI compare to synchronous SRAM alternatives for simpler embedded designs?
Unlike synchronous SRAMs that require a clock signal and specific setup/hold timing, IS62LV256AL-45ULI is a fully asynchronous device with 45 ns access time that responds directly to address and control signals. This simplifies interfacing with 8-bit microcontrollers and FPGAs that support asynchronous bus protocols, eliminating the need for clock domain management and reducing firmware complexity.
What lead time and packaging details should procurement teams consider for IS62LV256AL-45ULI?
IS62LV256AL-45ULI carries a factory lead time of approximately 10 weeks and comes in a 28-pin SOP package with 0.330 mm lead pitch. For programs with tight schedules, procurement should maintain safety stock given the 10-week replenishment cycle, and verify that the SOP-28 footprint matches PCB layout requirements before committing to a volume purchase order.
