CXA1100, CXA1101, CXA1102 and CXA1163 are ICs including two separate Dolby B type noise reduction processors. Seven devices with four Dolby levels and two types of package are provided for various applications. These devices feature very few external components, which is achieved by integrated filter circuits using integrated thin film capacitors with high capacitance.
• Minimum number of external components
• NR ON/OFF and REC/PB switchs included
• Small package (DIP16, SOP16)
• Small supply current (~5.5mA, Typ.)
• Dual channel processors in one chip

10. JEDEC Approved Byte-Wide Pinout
The X28HC64 is an 8K x 8 E2PROM, fabricated with Xicor’s proprietary, high performance, floating gate
CMOS technology. Like all Xicor programmable non-volatile memories the X28HC64 is a 5V only device. The X28HC64 features the JEDEC approved pinout for byte-wide memories, compatible with industry standard RAMs.
The X28HC64 supports a 64-byte page write operation, effectively providing a 32µs/byte write cycle and enabling the entire memory to be typically written in 0.25 seconds. The X28HC64 also features DATA Polling and Toggle Bit Polling, two methods providing early end of write detection. In addition, the X28HC64 includes a user-optional software data protection mode that further enhances Xicor’s hardware write protect capability.
Xicor E2PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years.
