Additional Details

The W24257AJ-20 is organized as 32,768 words by 8 bits. It supports read and write operations controlled by standard chip enable (/CE), output enable (/OE), and write enable (/WE) signals. The chip is fabricated using advanced CMOS technology, which contributes to its low power consumption and high speed. It's often used in systems where data needs to be accessed quickly and reliably, such as in data buffering or program storage.

The device typically comes in a 28-pin DIP, SOJ, or TSOP package. The specific package affects the physical dimensions and mounting options. The SRAM is designed to operate within a supply voltage range of 4.5V to 5.5V. Proper decoupling capacitors should be used to minimize noise on the power supply lines. The device is RoHS compliant and lead-free.
