The 25LC160D-I/ST is a 16K, SPI bus serial EEPROM memory device. It can be used for storing data such as calibration constants, design parameters and user information. The 25LC160D-I/ST has an access time of 6µs, a clock speed of up to 5 MHz, and is available in 8-pin PDIP, 8-pin SOIC, and 8-pin TSSOP packages. It is also available with software write protectability.The 25LC160D-I/ST is a SPI bus serial EEPROM in the 25x family of serial EEPROMs, which offers very low-power operation, fast access times and a low standby current.

Memory Field Application

The most common applications of the 25LC160D-I/ST serial EEPROMs are in industrial and automotive products. Applications include automotive engine control, industrial process control, computer input/output, data acquisition, and programmable logic controllers. The 25LC160D-I/ST is ideal for use in environments where high temperature and vibration are present.

Working Principle

The 25LC160D-I/ST chip uses synchronous Serial Peripheral Interface (SPI) for communication. The serial data transmission consists of a serial clock (SCLK), a serial input (SI) to load data from the master, and a serial output (SO) to shift data to the master. The 25LC160D-I/ST supports single- and double-byte instructions, including write status register, read status register, write data, read data, write disable, write enable and chip erase. The chip is divided into 32 pages, with each page having 512-bits of data. The 25LC160D-I/ST supports both sequential and random access modes.

The 25LC160D-I/ST supports write protection levels on user-defined segments of the memory space. The write protect pin (WP) supports up to four memory segment write protection levels, while the software write protect feature (SWP) allows certain memory ranges to be protected from any write operation.

The 25LC160D-I/ST has a control register that can be used to control the operation of the device. It can be set to either normal or power-saving mode. In the power-saving mode, the chip consumes only 0.4µA when idle and 8µA when active. The power-up current is 400µA.

In addition, the device also supports an external voltage-sense pin (VS) to detect the supply voltage range. The sensing range is 0.9V to 5V. The device supports a reset pin (RST) to reset the device after a power-on or any other reset condition.

The 25LC160D-I/ST has an operating temperature range of -40C to +105C. The chip also has an industrial temperature range of -40C to +125C. The package is designated as 8-pin PDIP, 8-pin SOIC and 8-pin TSSOP, with total dimensions of 6.225mm x 8.16mm x 0.7mm.

In summary, the 25LC160D-I/ST is a 16K, SPI bus serial EEPROM memory device that offers very low-power operation, fast access times and a low standby current. It is ideal for use in industrial and automotive products, and can be used to store data such as calibration constants, design parameters and user information. The 25LC160D-I/ST supports write protection, voltage sensing, and several other features. It is available in multiple package styles and temperature ranges.
