Zilog. Z87010

The Z87010 and Z87L10 are distinct 5V and 3.3V versions of the ADPCM Audio Encoder/Decoder. For the sake of brevity, all subsequent references to the Z87010 in this document also are applicable to the Z87L10, unless specifically noted. The Z87010’s single cycle instruction execution and Harvard bus structure promote efficient algorithm execution.

GENERAL DESCRIPTION

The Z87010/Z87L10 is a second generation CMOS Digital Signal Processor (DSP) that has been ROM-coded by Zilog to provide full-duplex 32 Kbps, Adaptive Delta Pulse Code Modulation (ADPCM) speech coding/decoding (CODEC), and interface to the Z87000/Z87L00 Spread Spectrum Cordless Telephone Controller.
