The AT28C256E-20FM/883 is a high-speed static random-access memory divisible into two blocks with each block containing 128 kilobits (8 bits per bit). The device is organized as 32K x 8 and uses page mode operation for fast access. This memory device can be used for a variety of applications, ranging from microcontrollers to digital signal processing. It is also used in industrial and consumer products, including laptop computers and digital cameras.

The AT28C256E-20FM/883 uses non-volatile Electrically Erasable Programmable Read-Only Memory (EEPROM) cells to provide programmable memory. The memory cells are programmed by the application. Data is retained when the system is powered down, making the EEPROM cells a reliable data storage medium. The memory can also be programmed in-system using the W53C256 programmable device.

The AT28C256E-20FM/883 features asynchronous read and write access times, external data input/outputs and a programmable control logic. The device’s asynchronous access times are significantly faster than synchronous access times, allowing for faster data transfers. The memory device also features an on-chip data protection circuitry for improved system reliability. The external data input/outputs allow for connections to external devices such as memory controllers and microcontrollers. The programmable control logic provides the ability to customize the device for specific applications.

The AT28C256E-20FM/883 is designed to operate at voltages ranging from 5V to 3.3V. It offers a fast initialization time and low power consumption. The device is manufactured using advanced CMOS technology and is the latest in a line of high-performance EEPROM products from Atmel. The AT28C256E-20FM/883 is rated at a maximum frequency of 40 MHz and a maximum access time of 180 ns.

The AT28C256E-20FM/883 comes with an on-chip self-programmable Flash controller that enables the device to both read and write memory cells. The controller can be used to program the device with a simple program or used for control purposes. The flash controller can access both the on-chip and off-chip memory. All of the external data I/O signals used to access the memory cells are furnished with the AT28C256E-20FM/883 device.

The AT28C256E-20FM/883 also features an on-chip microcontroller core. This core can be used to enhance the system performance with programs for on-chip data flow control and to provide support for externally supplied control signals. The microcontroller core is compatible with the Atmel AVR microcontroller family.

In summary, the AT28C256E-20FM/883 is a high-speed static random-access memory divisible into two blocks with each block containing 128 kilobits (8 bits per bit). It has a fast initialization time, low power consumption and is suitable for a wide range of applications. It is compatible with the Atmel AVR microcontroller family and is equipped with an on-chip self-programmable flash controller and a microcontroller core.
