W8NA80 More Information

Mfg: N/A


  One or more of the following United States patents apply: 4,454,488; 4,616,197; 4,670,681; and 4,760,352.   Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufac-   turer. 3. Applies over the specified range of operating temperature. 4. Applies over the specified range of operating power supply voltage. 5. The design, manufacturing process, and specifications of this device are subject to change without notice. 6. The maximum modulation bandwidth (and data rate) is dependent on the characteristics of the external encoding circuitry (not included). 7. Unless noted otherwise, case temperature TC = +25C 2C, test load impedance = 50 Ω, and modulation input is at logic HIGH. 8. The maximum operating current occurs at the maximum specified power supply voltage and maximum specified operating temperature. 9. Standby current is defined as the supply current consumed with the modulation input at logic LOW. 10. Improper antenna loading affects performance of HX device.

The W8NA80 is a high-performance electrically erasable programmable read only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits. Manu- factured with Atmels advanced nonvolatile CMOS technology, the device offers access times to 200 ns with power dissipation of just 54 mW. When the device is deselected, the CMOS standby current is less than 20 µA.    (continued)


PSCK and ASCK are the clocks for the PCM and ADPCM data streams, respectively. They must be high during the transition of CE. Note that PSCK and ASCK are shown as gated clocks as an option to conserve power. PSCK and ASCK need only be valid while CE is high.
