AS7C4098A-20JCNTR belongs to a family of non-volatile static RAM (NVSRAM). It provides the best of memory technologies, combining the speed of SRAM and the non-volatility of EEPROM. This device is ideal for use in embedded control applications that require low power consumption, reliable data retention, and fast access times.

Application Field

The AS7C4098A-20JCNTR can be used in a wide variety of applications, both in industrial and consumer markets. Industrial applications include programmable logic controllers (PLCs), intelligent instruments, vending machines, data loggers, and factory process control. Consumer applications include security systems, remote control systems, automotive applications, and smart cards.

In addition to these, AS7C4098A-20JCNTR can be used for data retention in power supplies, for data buffering, for operand storage in microcontrollers, and in programmable logic controllers (PLCs).

Working Principle

AS7C4098A-20JCNTR is composed of a non-volatile storage configured as a bank of 8Kbytes. It has an asynchronous CMOS control circuitry and an on-chip low-power supply regulator.The low-power operation mode allows power requirements to be reduced when the device is not in use.

AS7C4098A-20JCNTR’s asynchronous control circuitry provides users with the flexibility to use either 8-, 9-, or 10-bit data bus access. This allows for an easy migration from existing 8-bit systems, as well as ensuring efficient data transfer for 9- and 10-bit systems. The device also features a random access memory (RAM) mode which allows for reading and writing of data on-the-fly, and a burst read mode which allows for quick access to a range of data.

AS7C4098A-20JCNTR incorporates advanced features such as EEPROM cell reliability and power-on self-recalibration that allows it to maintain data integrity during power cycling while at the same time achieving a dramatic reduction in current consumption. All these features make the AS7C4098A-20JCNTR an ideal choice for embedded memory applications.
