PDM31564

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. Appropriate thermal calculations should be performed in all cases and specifically for those where the chosen package has a large thermal resistance (e.g., TSOP). The calculation should be of the form: Tj = Ta + P * _ja where Ta is the ambient temperature, P is average operating power and _ja the thermal resistance of the package. For this product, use the following _ja values:SOJ: 59/W    TSOP: 87/W

The PDM31564 is a high-performance CMOS static RAM organized as 262,144 x 16 bits. The PDM31564 features low power dissipation using chip enable (CE) and has an output enable input (OE) for fast memory access. Byte access is supported by upper and lower byte controls.

The PDM31564 operates from a single 3.3V power supply and all inputs and outputs are fully TTLcompatible.The PDM31564 is available in a 44-pin 400-mil plastic SOJ and a plastic TSOP package for high-density surface assembly and is suitable for use in highspeed applications requiring high-speed storage.
