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.

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
Series
Series, in the context of electronic components, refers to the arrangement of components in a circuit. When components are connected in series, they form a single path for current to flow through. The total resistance of a series circuit is the sum of the individual resistances of each component. Series connections are often used to control the flow of current in a circuit, as the total resistance can be adjusted by changing the number or type of components in the series.

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.

2.375V~2.625V
Supply Voltage
Supply Voltage is the voltage required to power an electronic component. It is typically measured in volts (V) and is specified in the component's datasheet. The supply voltage must be within the specified range for the component to function properly. If the supply voltage is too low, the component may not function at all. If the supply voltage is too high, the component may be damaged.

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
Clock Frequency
Clock Frequency, measured in Hertz (Hz), is the rate at which an electronic component, such as a microprocessor or oscillator, generates electrical pulses. It determines the speed at which the component can process data and execute instructions. A higher clock frequency generally indicates faster performance, but also higher power consumption and heat generation. Clock Frequency is a crucial parameter for timing-sensitive applications, such as digital signal processing and real-time systems.

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.

Length
Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.

Description
The CY7C1470BV25, CY7C1472BV25, and CY7C1474BV25 are 2.5V, 2M x 36/4M x 18/1M x 72 synchronous pipelined burst SRAMs with No Bus Latency (NoBLT) logic. They are designed to support unlimited true back-to-back read or write operations with no wait states. The CY7C1470BV25, CY7C1472BV25, and CY7C1474BV25 are equipped with the advanced (NoBL) logic required to enable consecutive read or write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data in systems that require frequent read or write transitions. The CY7C1470BV25, CY7C1472BV25, and CY7C1474BV25 are pin-compatible and functionally equivalent to ZBT devices.
All synchronous inputs pass through input registers controlled by the rising edge of the clock. All data outputs pass through output registers controlled by the rising edge of the clock. The clock input is qualified by the Clock Enable (CEN) signal, which when deasserted suspends operation and extends the previous clock cycle. Write operations are controlled by the Byte Write Selects (BW-BW for CY7C1470BV25, BW-BW for CY7C1472BV25, and BW-BW, for CY7C1474BV25) and a Write Enable (WE) input. All writes are conducted with on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE1, CE2, CE3) and an asynchronous Output Enable (OE) provide for easy bank selection and output tri-state control. To avoid bus contention, the output drivers are synchronously tri-stated during the data portion of a write sequence.
