AT27LV256A-90TC

Memory is an essential component of modern computer systems. It is used to store important data, instructions, and state information. The AT27LV256A-90TC is a type of memory component used in computer systems.

The AT27LV256A-90TC is an 8 megabit (1 megabyte) CMOS nonvolatile Static RAM (SRAM). The device utilizes a 5-volt DC single-supply operating voltage and offers low power operation with a maximum active current of 2 mA and standby current of 75 μA. The device also features low operating and standby power dissipation of 600 mW and 5 mW, respectively.

The AT27LV256A-90TC is available in three package sizes: TSOP-44, SOIC-44, and DIP-30. It is widely used in applications such as consumer electronics, automotive, industrial, and embedded systems. The device has a maximum operating frequency of 8 MHz and a data retention voltage of 2.5 V.

The AT27LV256A-90TC uses a 16-bit wide, low power CMOS static RAM which stores data when the power is turned off. It can read data at 145 ns max and program data into memory at 1.2 us max. The device has a storage capacity of 8 Mbits (1M bytes), organized as 65536 words of 16 bits each. The device also has an onboard address counter, which can be used for reading and writing data sequentially.

The AT27LV256A-90TC also supports sleep-mode and read-while-write operation. It has an output enable signal and write enable signal, which can be used to control the access of data. The device also features error detection and correction, which helps to ensure the integrity of data stored in the device. Additionally, the device features a hardware Password Protection mode which prevents unauthorized access to the device.
