25AA256-I/SN

The 25AA256-I/SN is a memory device manufactured by Microchip Technology, Inc. It is a low-power, serial-to-parallel EEPROM Memory device. The 25AA256-I/SN is the industry standard memory device for small form factor applications, such as embedded systems, instrumentation, security, and automotive applications.

The 25AA256-I/SN is a 16-pin device and is available in either a SOIC (Small Outline Integrated Circuit) or an 8-pin TSSOP package. It requires only a single power supply voltage, with an operating voltage of 2.5 - 5.5V. It has a low active current of only 5 μA and a standby current of 5 nA, which makes it ideal for battery-powered applications.

The 25AA256-I/SN can store up to 256K of addressable memory, with 16Kbyte page sizes that can be written to in one operations. It has a fast write cycle time of 1.78ms and a data read cycle time of 200ns. It also features self-timed erase and write cycles, allowing multiple data write operations to be performed in quick succession. The device also has an enhanced ESD/Latch-up protection, making it ideal for use in rugged environments.

When used with a serial interface such as I²C or SPI, the 25AA256-I/SN can be easily accessed and controlled by a microcontroller or host processor. Using either I²C or SPI, the 8-bit address instruction can access individual 16KByte page blocks. It also has bit, byte and page write capability, making it useful for both data retrieval and recording.

The 25AA256-I/SN is an ideal device for small form factor applications that require high speed data recording and retrieval, as well as low power consumption. The wide supply voltage range makes it suitable for use in automotive, industrial, and medical applications, as well as many other embedded systems. The enhanced ESD/Latch-up protection and the fast write cycle time make it ideal for use in harsh environments.

The 25AA256-I/SN provides optimal performance and reliable operation in a wide range of applications, from embedded systems to industrial applications. It is a suitable memory device for a variety of applications and can be used for data recording and/or retrieval.
