Seven Signal Serial Control Interface to ZiLOG Modem Data Pumps Application Note
●Applications such as television set-top box use a low speed embedded modem to transfer small amounts of data over the telephone network. It may be desired to eliminate redundant silicon in such a system by connecting the modem data pump directly to a host processor in the application.
●Some host processors, especially if included in an ASIC, may have a limited number of signal pins available to control the modem data pump. Normally host interface to Zilog data pumps is through the parallel port, which requires a interface of fifteen (15) signal pins. This application note will demonstrate how to connect ZiLOG modem data pumps to a host processor, with as few as seven (7) signal lines.
●It is possible to interface a controller to the Z02201, Z02202, Z02922 or Z02923 Modem Data Pump in a serial fashion with as few as seven signals using a small number of standard TTL parts. This note describes an interface using six output signals (/RD, /WR, CLK, and address lines A0, A1 and A2), and one bi-directional signal for serial data (SERDAT).
