What are the key features of IS61WV3216BLL-12TLI?

  • 12 ns maximum asynchronous access time with a 32K×16 organization (512 Kbit total) enables direct bus-interface operation at clock rates up to 83 MHz without wait states on 3.3V logic systems
  • 16-bit data bus width (×16 I/O) doubles throughput versus ×8 alternatives in the same 512 Kbit density, reducing bus cycle count for wide data-path microcontrollers and DSPs
  • Low-voltage 3.3V supply with a 44-pin TSOP-II (R-PDSO-G44) surface-mount package and Pb-free construction for RoHS-compliant, space-efficient embedded memory subsystem designs

What is IS61WV3216BLL-12TLI used for?

The IS61WV3216BLL-12TLI is widely deployed as a fast asynchronous work-RAM or frame buffer in embedded systems including FPGAs, DSPs, and microcontroller-based designs that require a 512 Kbit external SRAM with sub-15 ns access time on a 3.3V rail. Its 32K×16 organization suits 16-bit bus architectures common in communication equipment, industrial real-time controllers, and network packet buffers where low latency is critical. The 44-pin TSOP-II footprint integrates compactly onto multilayer PCBs alongside host processors in space-constrained designs such as video capture cards, protocol analyzers, and embedded vision modules.

Frequently Asked Questions

What is the access time and memory organization of the IS61WV3216BLL-12TLI SRAM?

The IS61WV3216BLL-12TLI provides a maximum asynchronous access time of 12 ns at 3.3V, organized as 32K addresses × 16-bit data words for a total density of 512 Kbits (524,288 bits). This 12 ns speed grade allows direct interfacing to bus masters running at up to 83 MHz without software wait states, making it suitable for real-time data buffers, FIFO memories, and cache scratch-pads in 16-bit embedded systems.

How does the 16-bit (×16) data bus of IS61WV3216BLL-12TLI benefit DSP and FPGA memory designs?

The ×16 data width transfers 16 bits per bus cycle compared to only 8 bits from a ×8 SRAM at the same 512 Kbit density, doubling effective bandwidth at equivalent clock rates. For a DSP or FPGA reading 32-bit words, only 2 bus cycles are needed instead of 4, reducing memory-access overhead by 50%. At 12 ns per access, this translates to peak bandwidth of approximately 1.33 Gbps on a 16-bit bus, which is sufficient for full-rate 720p video line buffering and high-speed protocol state machines.

What package does IS61WV3216BLL-12TLI use and what is its PCB footprint benefit over DIP alternatives?

The IS61WV3216BLL-12TLI uses the TSOP-II 44-pin (R-PDSO-G44) surface-mount package, which occupies a board footprint of approximately 18.4 mm × 10.2 mm at 0.8 mm pin pitch. Compared to a 44-pin DIP SRAM that requires through-hole vias and occupies over 55 mm × 15 mm, the TSOP-II package reduces PCB area by more than 50%, enables automated SMT placement, and allows routing on inner PCB layers beneath the component for multi-layer board designs.

What is the lead time for IS61WV3216BLL-12TLI and how should engineers plan SRAM procurement?

ISSI lists a 10-week factory lead time for the IS61WV3216BLL-12TLI, which is typical for specialized SRAM devices with low-volume demand. Engineering teams targeting a product launch should place orders at least 12 weeks before the production start date to account for potential queue fluctuations. Holding a buffer stock of 500 to 1000 units covers approximately 2 to 4 months of production at typical embedded-system volumes and guards against lead-time extensions caused by wafer-fab capacity constraints common for specialty 512 Kbit SRAM die.
