Description
Overview
The ISSI IS61WV5128BLL-10TLI is a high-performance, low-power 4Mb (512K × 8-bit) asynchronous static RAM manufactured by Integrated Silicon Solution Inc. (ISSI). Sourced directly from Digi-Key, this is a guaranteed authentic component — no counterfeits, no surplus grey-market stock. Whether you’re prototyping a microcontroller design, building an FPGA memory interface, or replacing a failed chip on a PCB, this SRAM delivers reliable, fast access times in a compact surface-mount package.
Key Specifications
- Organization: 512K × 8 bits (4Mb total)
- Access Time: 10 ns (ultra-fast asynchronous operation)
- Supply Voltage: 2.7V – 3.6V (3.3V nominal, 5V I/O tolerant)
- Package: 32-pin TSOP II (thin small-outline package) — surface-mount friendly
- Temperature Range: Industrial (-40°C to +85°C)
- Operating Current: Typically 25 mA active; ultra-low standby ~1 µA
- Interface: Fully asynchronous, parallel — easy to interface with any MCU or FPGA
- Data Retention: Unlimited write cycles — true SRAM, not flash
- RoHS Compliant: Yes (lead-free, halogen-free)
Condition Details
This component is in Like New condition — used only once or twice during initial testing or prototyping. There are absolutely no signs of physical wear, no bent pins, no solder residue, and no thermal stress marks. The chip appears indistinguishable from brand-new stock. As confirmed by the seller, this unit was originally purchased from Digi-Key, ensuring full authenticity and traceability to a reputable distributor.
