IS61WV102416DBLL-10TLI 概要
Asynchronous static RAM (SRAM) is a volatile memory technology that retains data as long as power is applied, without the refresh cycles required by DRAM. Within the broader memory hierarchy, SRAM sits closest to the processor because of its sub-15 ns access times; it is used for cache, look-up tables, scratch-pad buffers, and FIFO storage in networking, industrial, and embedded systems. Compared with synchronous SRAM (such as QDR or DDR SRAM), asynchronous SRAM uses simple chip-enable, output-enable, and write-enable control signals and is ideal for glue-less processor bus interfaces.
The IS61WV102416DBLL-10TLI provides fully static operation (no clock required), TTL-compatible I/O levels, common data-in/data-out bus architecture, and an active-low output enable for bus sharing. Power consumption is minimized through a Chip Enable power-down mode, and the device supports industrial temperature range operation. The CMOS fabrication process delivers high noise immunity and low standby current, both of which are critical for battery-backed or energy-conscious designs.
Typical applications include industrial controllers, networking line cards, routers and switches requiring fast look-up tables, automotive telematics (non-safety-critical subsystems), medical instrumentation buffers, RAID controllers, and any embedded CPU/MCU design that needs a large, low-latency external data store beyond the on-chip SRAM budget. The wide word width (x16) is well matched to 16-bit and 32-bit microcontrollers and DSPs.
When designing with this device, keep in mind that asynchronous SRAM bandwidth is limited by the controller's ability to issue back-to-back read or write strobes, so the 10 ns access time implies roughly 100 MHz equivalent single-transfer throughput per cycle. Decoupling and signal routing must be handled carefully on long busloads to maximize margin.

主な用途
IS61WV102416DBLL-10TLI の用途: 6 件s: Industrial Controller Scratch-Pad Memory, Networking Router / Switch Look-Up Table, Automotive Infotainment / Telematics Buffer, Medical Instrumentation Data Buffer, RAID Controller Cache Memory, Embedded CPU/MCU External Data Store.
Industrial Controller Scratch-Pad Memory
The IS61WV102416DBLL-10TLI provides a 2 MB asynchronous SRAM scratch pad for industrial PLCs, HMI panels, and motion controllers. The 10 ns access time and 1M x 16 organization give 16-bit MCUs and DSPs a deterministic, glue-less external memory that needs no controller overhead. Operating from 2.4-3.6 V it tolerates loosely regulated 24 V->3.3 V rails common in industrial racks, and the industrial -40C to +85C temperature range ensures reliable operation on factory floors.
おすすめ
Networking Router / Switch Look-Up Table
In routers, switches, and firewalls the IS61WV102416DBLL-10TLI is used as a fast parallel look-up table for routing entries, ACL tables, and packet buffers. The 10 ns access time supports line-rate look-ups at typical 100 MHz forwarding clock, and the 16-bit bus aligns with standard network processor datapaths. The wide 2.4-3.6 V supply range simplifies power tree design across router line cards.
おすすめ
Automotive Infotainment / Telematics Buffer
The IS61WV102416DBLL-10TLI serves as a fast external buffer for automotive infotainment head units and telematics control units (non-safety-critical subsystems). The 1M x 16 organization provides ample scratch space for navigation maps, audio DSP delay lines, and CAN/LIN gateway buffers. The wide operating voltage eases integration into 12 V automotive battery rails with linear regulation, and the industrial temperature range covers in-cabin environments.
おすすめ
Medical Instrumentation Data Buffer
In ultrasound carts, patient monitoring stations, and portable diagnostic devices, the IS61WV102416DBLL-10TLI acts as a high-speed FIFO between the analog front end and the host DSP. The 10 ns access time keeps up with high-sample-rate ADCs, while the 16-bit bus matches typical medical imaging pipelines. Low standby current and TTL-compatible I/O simplify battery-powered handheld instrument designs.
おすすめ
RAID Controller Cache Memory
RAID controllers use asynchronous SRAM as a write-back cache to absorb burst writes from the host before draining to disk. The IS61WV102416DBLL-10TLI's 10 ns access time and 1M x 16 organization give 2 MB of low-latency cache that fits typical small-RAID or SSD controller architectures. The 48-pin TSOP-I footprint simplifies board layout next to SATA/SAS controller ASICs.
おすすめ
Embedded CPU/MCU External Data Store
Many 16-bit and 32-bit MCUs ship with only a few hundred KB of internal RAM, insufficient for buffering sensor streams or graphics frame data. The IS61WV102416DBLL-10TLI provides 2 MB of external storage with a simple asynchronous bus interface - no SDRAM controller, no refresh cycles. It pairs directly with the external memory bus of most Cortex-M, RX, and dsPIC devices, freeing the internal SRAM for deterministic real-time tasks.

主な差別化要因
- Wide 2.4 V to 3.6 V supply supports loosely regulated rails （vs IS61WV102416BLL-10TLI (3.3 V +/- 0.3 V))
- Same 48-pin TSOP-I pinout across ISSI family for PCB reuse （vs CY7C1061AV33-10ZXI (54-pin TSOP-II))
- Industrial -40C to +85C temperature range standard （vs Consumer-grade 0C to +70C SRAM)
設計ノート
Route address and data buses with matched trace lengths and 50 ohm controlled impedance on the 48-pin TSOP-I footprint. Place at least one 0.1 uF ceramic decoupling capacitor close to each VCC pin (pin 23) and a bulk 10 uF tantalum or ceramic capacitor near the package. The wide 16-bit bus is sensitive to skew; avoid running address lines parallel to noisy clock or switching-power traces for more than 25 mm.
Do not leave Chip Enable (CE1-bar) floating. CE1-bar must be driven low during the access cycle; a floating CE can cause the device to enter an undefined state and draw elevated supply current. Similarly, UB-bar and LB-bar must be tied to GND when byte-write control is not used, otherwise I/O bus contention can occur. According to the ISSI datasheet, OE-bar should never be asserted before CE1-bar goes active.
Active supply current scales with read/write frequency. Estimated: at 10 ns cycle (100 MHz equivalent) the IS61WV102416DBLL-10TLI typically draws 90-110 mA active, but in standby (CE1-bar high) it drops below 5 mA. Use chip-enable power-down aggressively in battery-backed designs: gate CE1-bar with the host MCU's chip-select to achieve >90% current reduction during idle periods.
Because asynchronous SRAM relies on address-to-data timing rather than a clock, hold and setup margins must be validated across voltage and temperature. According to the ISSI datasheet, output hold time after OE-bar rising edge is at least 2 ns; designers should sample data on the rising edge of OE-bar (or equivalent strobe) and add 1-2 ns of margin in production test to absorb process variation at the temperature corners.
