GENERAL DESCRIPTION (Continued)

ICs. As configured by the Zilog-provided embedded soft-

ware for digital cordless phones, the Z87010 supports a

low-cost 8-bit

µ-law telephone CODEC. The Z87010 is to

be used with the Z87000 and operates at 16.384 MHz, pro-

viding 16 MIPS of processing power needed for the cord-

less telephone application.

Notes: All signals with a preceding front slash, ‘/’, are

active Low, e.g., B//W (WORD is active Low); /B/W (BYTE

is active Low, only).

Power connections follow conventional descriptions be-
