| Z02215 Single-Chip Modem ZiLOG (R) 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 lengthy modem design and approval process by taking the guesswork out of software design. It is a major improvement over the previous method of designing with a separate modem controller. ZiLOG provides a software utility called DiplomatTM to speed system development by allowing you to make controller code changes quickly. Parameter tables for 12 countries and CTR21 are provided, which give you a huge advantage when doing modem precertification testing. Design and certification times can be reduced 50 percent or more by using the Z02215 and ZiLOG's software tools. The Z02215 is specifically designed for transaction processing applications such as point-of- sale and smart card terminals, set-top boxes, and security applications It can also be applied to applications that require data transmission and reception of up to 2400bps. 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.
