Z02215 Single-Chip Modem
A single-chip modem that simplifies design
and certification
ZiLOG’s single-chip modem is a highly integrated
modem solution for remote data transmission, transaction processing, and telemetry. The DSP-based Z02215
simplifies modem design and PTT certifications, enabling
you to focus on application design, rather than modem
design.
ZiLOG provides a total solution
The Z02215 includes the modem controller, data pump,
and analog front end, all in one package. It solves the

Z02215 includes a V.22bis data pump with improved analog front end and a Z80-style microprocessor that serves
as the modem controller. System costs are reduced
since all of the RAM and ROM necessary to operate the
modem are included on-chip.
