The IS64LPS204818B-166TQLA3-TR is a member of the IS64 family of RAM (Random Access Memory) devices manufactured by ISSI (Integrated Silicon Solutions Inc). It is a low-power, high density, multi-bank synchronous dynamic random access memory based on the DDR-SDRAM architecture. The device is designed to operate over multiple supply voltages, with a maximum voltage of 1.8 volts. It is designed to be used in a wide range of applications, from consumer electronics to industrial control systems.

The IS64LPS204818B RAM has a single or two-bank architecture. Each bank consists of 64Mbits (8M x 8) of memory built from 4M x 16 DRAM chips. The device has a total organization of 2048K x 16 and is organized as a 16-bit device. It has a maximum access time of 18ns, a maximum clock rate of 166MHz, and a Data Bus width of 16-bits. The device also has built-in self-refresh and self-calibration capabilities.

The IS64LPS204818B RAM can be used in a variety of applications including real-time data processing, memory-mapped I/O, industrial control systems, embedded systems, high-speed networking, and many others. The device is designed to be used with devices operating at various supply voltages ranging from 1.7V to 1.8V.

In terms of its working principle, the IS64LPS204818B-166TQLA3-TR operates in a synchronous manner, whereby the operations between the clock and the memory are synchronized. The device has built-in circuitry to handle the pump-up and pump-down conditions inherent in dynamic RAM operations. The device uses an external clock source to synchronize its operations. The clock rate is determined by the external clock source, which is set in the design of the system. The maximum clock rate of 166MHz is derived from the external clock.

The device also has deep power-down mode, a feature that enables lower power consumption when the memory is not in use. This feature is particularly useful in applications where power consumption is critical. Additionally, the device has self-refresh and self-calibration capabilities, which ensure that data stored in the memory is accurate and reliable.

Overall, the IS64LPS204818B-166TQLA3-TR is a highly versatile device, capable of providing reliable and fast memory operations over a wide range of supply voltages. Its low-power, high-density design makes it particularly well-suited for applications where power requirements are critical. Its self-refresh and self-calibration capabilities also ensure that data stored in the memory is accurate and reliable.
