The IS61C5128AS-25TLI is a 128Kx8bit low power and high performance Static RAMs (SRAMs) which offer fast access time and low active power. These SRAMs are ideal for applications such as mobile phones, PDAs, gaming consoles and laptop computers. They are also suitable for use in compact devices that require minimal power. This SRAM is available in three different package types such as LQFP, TFBGA and TSOP.

The IS61C5128AS-25TLI uses a silicon-on-insulator (SOI) process for fabricating the device and uses a voltage range of 2.4 to 2.9V. The device has a programmable real time clock/calendar, an internal 2K-word read/write RAM, and an internal power down controller. The device has two power-saving modes: Sleep and Power Down. In Sleep mode, the device is put in idle by setting a single bit, while in Power Down mode the device is completely shut off and the clock is stopped to reduce power consumption. The device features a typical access time of 25ns and a typical standby current of 10uA.

The IS61C5128AS-25TLI is a nonvolatile SRAM meaning that it can retain data without the need for an external power source. It uses a ferro-magnetic layer between the DRAM and SRAM cells to achieve the nonvolatile function. This SRAM is capable of storing up to 128Kx8-bits of data in a single chip. The device has an extended temperature range of -55C to +100C and is resistant to radiation. It also has enhanced IMD (In-System Memory Detection) designed to detect and isolate any defective SRAM cells.

The working principle of IS61C5128AS-25TLI is very simple yet highly effective. Its internal circuitry is designed for fast and reliable data access. It consists of cell arrays, internal logic circuits, and a row address multiplexer (RAM) to access the memory cells. When a row address is provided to the RAM, it uses the decoded address to select the corresponding row of memory cells. The data stored in the memory cells can then be accessed by decoding the column address. The internal logic circuitry also handles read and write operations while the RAM is accessing a row address.

The IS61C5128AS-25TLI is a versatile memory solution for numerous embedded applications. It can be used in automotive, robotics, consumer, industrial and medical applications. This type of SRAM is also used in applications such as multimedia devices, navigation systems, smart meters, security systems, and so on. In terms of larger-scale applications, this SRAM can be used in large-scale industrial controllers, telecommunications systems, digital signal processing systems, and embedded system designs. This SRAM is an ideal choice for systems that require low power consumption and fast access time.
