The CY7C1484BV33-250BZXC is a Synchronous SRAM that belongs to the memory family. It is specially designed for low power applications such as cellular phones, personal digital assistants, and so on. Furthermore, it can interface with ARM® Cortex™-M3, Cortex™-M4, ARM7TDMI™ and ARM9™ to provide more flexibility in design and power management. This article discusses how the CY7C1484BV33-250BZXC works and what its potential applications are.

Application fields

The unique features of CY7C1484BV33-250BZXC make it suitable for use in many applications. It operates on a single 3.3V power supply and its maximum operating frequency is approximately 150 MHz. This makes it suitable for use in applications with higher speed and power requirements, such as mobile device applications and embedded systems. In addition, its wide range of operating temperature, from -40°C to 85°C, makes it suitable for various environments. Additionally, the device can support multiple connections and is suitable for use in parallel architectures, which makes it ideal for use in multiple processor architectures.

The CY7C1484BV33-250BZXC also has a small footprint, with its 48-pin TSOP-II (5x5mm) package occupying only 0.5mm2 of PCB space. This makes it perfect for use in devices with limited PCB space. Furthermore, its 3.6ns cycle time makes it suitable for medium-to-high speed applications.

Working Principle

The CY7C1484BV33-250BZXC operates as a synchronous, static RAM. This means that all operations are synchronized to a clock signal, such as a processor’s clock. The device consists of two 4-bit input/output ports and an 8-bit wide memory (1Kx8 bits). The 4-bit input/output ports are used for transfer of data to and from the memory, while the 8-bit wide memory stores the data.

The CY7C1484BV33-250BZXC can function as a 64K asynchronous static RAM, depending on user-selected options. When used as an asynchronous static RAM, the device operates similar to a conventional SRAM by awaiting an external control signal, such as a processor’s memory address. When used asynchronously, write and read operations are possible at any time and the read and write operations are not synchronized to a clock signal.

When used as a synchronous static RAM, the device uses a clock signal to control the read and write operations. This means that the write and read operations will be synchronized to the clock signal, allowing for more efficient data transfer. Furthermore, the device is capable of burst read/write operations, allowing it to transfer multiple bytes of data in a single cycle.

Conclusion

The CY7C1484BV33-250BZXC is a Synchronous SRAM that belongs to the memory family. It is specially designed for low power applications such as cellular phones, personal digital assistants, and so on. Furthermore, it can interface with ARM® Cortex™-M3, Cortex™-M4, ARM7TDMI™ and ARM9™ to provide more flexibility in design and power management. In addition, its wide operating temperature range, low power requirements, wide range of operating frequency, small footprint, and burst read/write capability make it suitable for many applications, including mobile device applications, embedded systems and multiple processor architectures.
