Additional Details

The CXK58256PM-70L typically comes in a 28-pin DIP (Dual In-line Package) or a surface-mount package. It requires a stable power supply for reliable operation. Decoupling capacitors should be placed close to the power supply pins to minimize noise. Data retention voltage is typically lower than the operating voltage. Always refer to the Sony datasheet for the exact data retention voltage specification.

Proper handling during assembly is crucial to prevent damage from electrostatic discharge (ESD). It's recommended to use ESD-safe handling procedures when working with this SRAM. Avoid exposing the device to excessive temperatures during soldering.
