A complete modem can be made by adding ZiLOG data pump (Z02201), phone line interface, and the required DTE interface. The Z02205 has been designed for low-cost use and includes a glueless interface to the ZiLOG data pumps. The Z02205 is ideal for applications where small size and low power consumption are requirements. The Z02205 operates over dial-up telephone connections, provides auto-dial and ring detect, and operates in either SYNC or ASYNC modes. The Z02205 includes AT command and modem control firmware in on-chip ROM. It also includes enhanced wakeup circuitry, programmable Watch-Dog Timers (WDT), and low-noise/EMI options. AT commands stored on-chip in ROM provide control over the following modem controller functions: PS001000-MOD0599 ‡ ‡ ‡ ‡ ‡ ‡ ‡ ‡ Call progress monitoring Handshake negotiation Dial controls—pulse or tone S-registers Auto-answer and auto-dial Guard tones On-hook and off-hook Auto-retrain Standard Z02205 sample devices and demonstration boards contain controller code tailored for operation on the North American phone network. For production usage, customers must modify the controller code to meet the requirements of their particular country and application. 1 Z02205 www.DataSheet4U.com Modem Controller ZiLOG Note: All signals with an overline, are active Low.
