Details
GENERAL DESCRIPTIONThe MSM7502, developed especially for low-power and multi-function applications in touchtone telephone sets and digital telephone terminals of digital PBXs, is a single +5 V power supply CODEC device. The device consists of the analog speech paths directly connectable to a handset, the calling circuit directly connectable to a piezosounder, the push-button key scanning interface between push buttons and control processors, the dial tone generator, them-law/A-law CODEC, and the processor interface. The functions can be controlled via 8-bit data bus.FEATURES• Single +5 V Power Supply• Low Power Dissipation Power ON Mode : 30 mW Typ. 53 mW Max.
