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.

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

NOTES: (For three previous Electrical Characteristics tables) 1. The parameter is tested with CL = 5 pF as shown in Figure 2. Transition is measured 200 mV from steady state voltage. 2. At any given temperature and voltage condition, tHZCE is less than tLZCE. 3. This parameter is sampled. 4. WE is high for a READ cycle. 5. The device is continuously selected. All the Chip Enables are held in their active state. 6. The address is valid prior to or coincident with the latest occurring Chip Enable. 7. Vcc = 5V 5%.
