Description
The PDM41024 is a high-performance CMOS static RAM organized as 131,072 x 8 bits. Writing is accomplished when the write enable (WE) and the chip enable (CE1) inputs are both LOW and CE2 is HIGH. Reading is accomplished when WE and CE2 remain HIGH and CE1 and OE are both LOW. The PDM41024 operates from a single +5V power supply and all the inputs and outputs are fully TTLcompatible. The PDM41024 comes in two versions: the standard power version (SA) and the low power version (LA). The two versions are functionally the same and differ only in their power consumption. The PDM41024 is available in a 32-pin plastic TSOP (I), and a 300-mil and 400-mil plastic SOJ.
High-speed access times Com'l: 10, 12 and 15 ns Ind'l: 12 and 15 ns Low power operation (typical) - PDM41024SA Active: 450 mW Standby: 50 mW - PDM41024LA Active: 400 mW Standby: 25mW Single +5V (±10%) power supply TTL-compatible inputs and outputs Packages Plastic SOJ (300 mil) - TSO Plastic SOJ (400 mil) - SO Plastic TSOP (I)- T

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: 72o C/W TSOP: 95o C/W 2 4/09/98 - Rev. 3.3
