IS62LV256AL-45TLI-TR are a type of Dual-Port Static CMOS RAM, ideal for use in applications where a fast access time of 45ns, low power consumption, and superior reliability are essential. These memory chips feature a maximum operating power of 90mW at 3.3V, with a low standby current of 0.3mA, making them the perfect choice for battery-based applications. IS62LV256AL-45TLI-TR are also capable of operating at temperatures ranging from -40°C to 85°C, making them suitable for use in a range of environments.

The IS62LV256AL-45TLI-TR features 256K bits of memory, organized in 32K words by 8 bits. It is manufactured with a 0.3um, 5-metal layer CMOS process. The memory is organized into 8 banks of 32K words each. The address pointer for each bank is separated into two bytes, allowing the memory to be operated in either big-endian (most-significant byte first) or little-endian (least-significant byte first) mode. The address space is divided into two equal halves, with each bank providing access to the same exact address space.

The IS62LV256AL-45TLI-TR memory is designed for two-port operations, allowing two separate read/write operations to be performed simultaneously from the same address space. Each port can access the same data independently, or they can be programmed to access different data at the same time. This two-port architecture enables high-speed data transfer, allowing for efficient applications such as video processing and data acquisition.

An on-chip register is available for setting various configurations. These configurations include write protect, ROM/RAM instruction set, ROM address decoding, wait cycle, auto address increment and size, endianness, and wait-state generation. This register can be programmed via the serial or parallel port.

The IS62LV256AL-45TLI-TR memory is ideal for use in communications, computer and peripheral equipment, automotive and industrial applications, and many other types of embedded systems. due to its high-speed access time, low power consumption, and versatility.

The IS62LV256AL-45TLI-TR memory chip works by utilizing a stack-access architecture, which functions by retaining the data in a queue, advancing write and read accesses in a continuous loop, thereby speeding the access time. Once access has occurred, the stack advances, and the next access can begin. This architecture eliminates the need for large onboard SRAMs and allows for maximum performance.

In summary, the IS62LV256AL-45TLI-TR is a powerful and reliable dual-port static CMOS RAM ideal for use in a variety of applications. Its low power consumption, high-speed access time, and versatile programming options make it an ideal choice for any embedded system. When compared to other similar memory chips, the IS62LV256AL-45TLI-TR stands out and provides an unparalleled performance and reliability.
