AT28C17E-15PC

AT28C17E-15PC is a kind of CMOS nonvolatile memory that combines EEPROM andRIOT (RAM/I/O port) in one chip. This kind of memory has a wide range of application fields, such as microprocessor based systems, digital communication systems, instrumentation systems, automotive, industrial control and other embedded systems. In addition, AT28C17E-15PC also has the characteristics of low power consumption, high speed, high reliability, large capacity and low cost. So, it’s very popular.

AT28C17E-15PC main features are as follows:

• 17,408 bits of nonvolatile EEPROM organized as 256 x 64 with separate control register.
• A separate high-speed RAM of 256 x 8 and dual-port RAM of 8 x 8.
• Versatile input/output port with eight bidirectional ports.
• Data input or output control through RD, WR and CE.
• Advanced CMOS technology provided 4mA output buffering and 10 ns maximum access time.
• High stability and reliability
• Low voltage design: Operate 2.7V to 5.5V.
• 5V/µs edge rate, enabling EEPROM I/O compatibility.
• 4ms/byte erase/write cycle time.
• 128 bytes of EEPROM page write.

AT28C17E-15PC working principle is that when the data is read from the EEPROM, the Address/Data register and latch enable pin LE can be used to select the contents of the Address and Data registers, and then the data is output from the chip outputs Q0-Q7. When writing data to the EEPROM, the LE and WR can be used to select the contents of the Address Data register and then write the data of Q0-Q7 data input to the wanted address that stored in the Address/Data register. Finally, the data is written to EEPROM after the completion of the internal time-delayed operation.

In summary, AT28C17E-15PC is a great memory device with a powerful combination of RAM, I/O port and nonvolatile EEPROM. With its wide range of application fields, it is widely used in modern digital systems and embedded systems. In addition, its low power consumption, high speed, high reliability, large capacity and low cost make AT28C17E-15PC an ideal choice for a variety of applications.
