AS7C1024B-15TJCN is a 1024K-bit (128K * 8) Serial CMOS EEPROM device. It belongs to the Memory in electronic devices, which is intended for general purpose applications. It is organized as 131,072 Pairs of 8-bit words, and occupies less than half of the space required for a standard parallel EEPROM. The device is expanded through 3-wire protocol and has a faster transfer rate than SPI devices.

The AS7C1024B-15TJCN is manufactured in a tiny 4-pin SOT-23 surface mount package -- which allows the device to be used in space-sensitive applications. It has a wide operating voltage range of 2.3V to 5.5V, using an I²C communication structure, and each device requires only one slave address. The device is available in three different package configurations: SOIC-8, TSSOP-8 and SOT-23.

AS7C1024B-15TJCN application field and working principle are the focus of the following content.

Application Fields

The AS7C1024B-15TJCN Serial CMOS EEPROMs are intended to provide cost-effective, non-volatile memory for applications requiring a small footprint and low power consumption. The non-volatile, electrically erasable, programmable memory (EEPROM) can be used for data storage in a variety of different applications, including industrial, medical, consumer and automotive.

In industrial applications, it can be used for data logging in devices that track industrial processes, such as temperature and pressure readings. In the medical field, it can be used for vital signs monitoring, patient identification and tracking. In consumer electronics, it is used for settings configuration and software protection. In automotive applications, it is used for fuel injection control and module parameters storage.

Working Principle

AS7C1024B-15TJCN Serial CMOS EEPROMs employ a 3-wire protocol— DATA, CLOCK and CHIP SELECT—to allow multiple devices to be connected to a single communication channel. The device is controlled by the CPU or logic circuit through the DATA and CLOCK lines. The CLOCK line validates the DATA line. The memory size is up to 128K-bit.

AS7C1024B-15TJCN can be programmed (programmable) and erased with 10 µs of instruction cycle time. The device can be written, erased and re-programmed to store up to 16 bits of data per instruction cycle. A single command can select either read or write mode with 13 programmable chips. No external components are required to interface with the device. The AS7C1024B-15TJCN also incorporates a number of on-board protection features that protect it against accidental exposures to various voltages and currents. The device is assembled in a standard four-pin SOT-23 package, with two of the pins used for power, and one each for DATA and CLOCK.

AS7C1024B-15TJCN is a very popular Serial CMOS EEPROM device due to its reliable, cost-effective and small size. The device provides a great solution for a variety of applications requiring small footprint and low power consumption. With its fast transfer rate and robust protection features, it has proven to be a valuable addition to any electronic system.
