23LCV512T-E/ST Application Field and Working Principle

The 23LCV512T-E/ST is a low-power serial SRAM device, facilitating the development of solutions catering the growing market demand for a cost-efficient memory devices with enhanced features. Looking past its features and specs, let us take a closer look at the 23LCV512T-E/ST application field and working principle.

Application Field

The 23LCV512T-E/ST is typically used in portable or battery-powered applications, and are suitable for use in consumer, automotive and industrial applications alike. It is designed to store profile settings for consumer applications, such as audio, video, gaming consoles and distance entertainment systems. Additionally, the memory device can provide the necessary data storage for industrial applications such as power supplies, motor control applications, medical systems, process control and communication systems.

The 23LCV512T-E/ST provides up to 16 Megabit of nonvolatile memory in a small serial-access package. The device operates over a Vcc range from 2.5 to 3.6 Volts. It contains two independent nonvolatile memory banks, each with its own control circuitry, that can be configured to store either 512K-bit of data in the lower bank, or 8 Megabit of data in the upper bank.

Features

The 23LCV512T-E/ST features three dedicated pins, used to select the upper or lower banks, to program and erase the memory. It also supports dual transfer rate of 10 MHz and 5 MHz. It requires two supply voltages to operate and offers 16 Megabit of fast program and erasure time. It is capable of storing up to 512K-bits of data in its lower bank, or 8 Megabit of data in the upper bank.The 23LCV512T-E/ST also features a low-power sleep mode, which reduces its power consumption during data operations. This allows for low-power consumption and extended battery life in portable or battery-powered applications.

Working Principle

The 23LCV512T-E/ST is an asynchronous, low-power serial SRAM device that is characterized by its self-timed programming and erase timing. This means that no external clock, external memory controller, or microcontroller is necessary to program and erase it. All data input, output and program and erase operations are carried out using serial communication lines.

The 23LCV512T-E/ST uses nonvolatile memory as its data storage element. The device comes programmed with 16 Megabits of nonvolatile memory array, organized as two independent “banks”. The lower bank contains 512K bits of memory and the upper bank contains 8 Megabits.

The device contains independent circuits for controlling the programming, erasing and reading of the data stored in each bank. The programming, reading and erasing of the data is performed by the 24-bit address and by the 4-bit instruction register.

An external microcontroller can be used to write and read data to and from the memory banks. The microcontroller is connected to the SRAM device using a serial communication interface, which can be either one of the two standard parallel bus protocols, the SPIE protocol or the SABP protocol.

Conclusion

The 23LCV512T-E/ST is an ideal device for applications requiring low-power and cost-effective memory solution. It supports dual transfer rate, is capable of storing up to 512K-bit or up to 8 Megabits of data, and can be programmed and erased using no external clock, microcontroller or memory controller. The device’s nonvolatile memory array makes it suitable for use in battery-powered applications, and its low-power sleep mode ensures extended battery life.
