Part Overview
Description
The IDT7025 is a high-speed 8K x 16 dual-port static RAM with true dual-ported memory cells that allow simultaneous reads of the same memory location. It features low-power operation, with active power consumption of 750mW (typ.) for the IDT7025S and 750mW (typ.) for the IDT7025L, and standby power consumption of 5mW (typ.) for the IDT7025S and 1mW (typ.) for the IDT7025L.
The IDT7025 easily expands data bus width to 32 bits or more using the Master/Slave select when cascading more than one device. It has on-chip port arbitration logic and full on-chip hardware support of semaphore signaling between ports. The device operates fully asynchronously from either port and supports battery backup operation with 2V data retention. It is TTL-compatible, operates from a single 5V (±10%) power supply, and is available in 84-pin PGA, Flatpack, PLCC, and 100-pin Thin Quad Flatpack packages.

  • Mounting Type

    Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include: * Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side. * Surface-mount: Component is placed on the surface of the PCB and soldered in place. * Press-fit: Component is pressed into place on the PCB without soldering. * Socket: Component is inserted into a socket on the PCB, allowing for easy replacement. The mounting type is determined by factors such as the component's size, shape, and power requirements.

    Surface Mount
  • Package / Case

    Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

  • Supplier Device Package
    84-PLCC (29.21x29.21)
  • Operating Temperature

    Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

    -40°C~85°C TA
  • Packaging
    Tape & Reel (TR)
  • Part Status

    Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

    Obsolete
  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

  • Technology

    Technology, in the context of electronic components, refers to the specific manufacturing process and materials used to create the component. It encompasses the semiconductor fabrication techniques, such as the type of transistor used (e.g., MOSFET, BJT), the gate oxide thickness, and the interconnect materials. Technology also includes the packaging type, such as surface mount or through-hole, and the leadframe or substrate material. The technology used impacts the component's performance characteristics, such as speed, power consumption, and reliability.

  • Memory Type

    Memory Type refers to the type of memory technology used in an electronic device. It indicates the specific design and architecture of the memory, such as DRAM (Dynamic Random Access Memory), SRAM (Static Random Access Memory), ROM (Read-Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), or Flash memory. Each memory type has unique characteristics, including speed, capacity, volatility, and cost, which determine its suitability for different applications.

    Volatile
  • Access Time

    Access time is the time it takes for a memory device to retrieve data from a specific location. It is typically measured in nanoseconds (ns) and is a critical factor in determining the performance of a computer system. The lower the access time, the faster the memory device can retrieve data and the faster the computer can perform tasks.

    55ns
  • Memory Format

    Memory Format refers to the arrangement and organization of data within a memory device. It specifies the number of bits, bytes, or words stored in each memory location and how they are accessed.
