Z02215 Single-Chip Modem  
A single-chip m odem that sim plifies design  
and certification  
ZiLOGs single-chip m odem is a highly integrated  
m odem solution for rem ote data transm ission, transac-  
tion processing, and telem etry. The DSP-based Z02215  
sim plifies m odem design and PTT certifications, enabling  
you to focus on application design, rather than m odem  
design.  
ZiLOG provides a total solution  
The Z02215 includes the m odem controller, data pum p,  
and analog front end, all in one package. It solves the  
lengthy m odem design and approval process by taking  
the guesswork out of software design. It is a m ajor  
im provem ent over the previous m ethod of designing  
with a separate m odem controller.  
Features  
• Com plete m odem integrated circuit with  
integrated controller, data pum p and Analog  
Front End (AFE) with active hybrid  
• Data m odem throughput to 2400 bps  
- ITU V.22bis, V.23, V.22, V.21  
- Bell 212A, Bell 103, Bell 202, Bell 202T  
- V.23 with Minitel line reversal  
ZiLOG provides a software utility called Diplom atTM to  
speed system developm ent by allowing you to m ake con-  
troller code changes quickly. Param eter tables for 12  
countries and CTR21 are provided, which give you a  
huge advantage when doing m odem precertification test-  
ing. Design and certification tim es can be reduced  
50 percent or m ore by using the Z02215 and ZiLOGs  
software tools.  
V.14 asynchronous to synchronous conversion  
Speed m atching and RTC/CTS flow control  
between the m odem and the term inal  
• Line-in-use detection before connection, and  
Pick-up detection during connections  
Supports tone or pulse dialing  
• Call progress m onitoring  
• Program m able transm it attenuation and  
selectable receive threshold  
The Z02215 is specifically designed for transaction pro-  
cessing applications such as point-of- sale and sm art  
card term inals, set-top boxes, and security applications  
It can also be applied to applications that require data  
transm ission and reception of up to 2400bps. The  
Z02215 includes a V.22bis data pum p with im proved ana-  
log front end and a Z80-style m icroprocessor that serves  
as the m odem controller. System costs are reduced  
since all of the RAM and ROM necessary to operate the  
m odem are included on-chip.  
• Dynam ic power m anagem ent  
• North Am erican Type-I Caller ID  
• 44-Pin VQFP footprint  
Benefits  
• Proven technology  
• Reduce tim e to m arket by 50%  
Sim plify global m odem certifications  
• Easy to integrate  
• Quick design tim e  
Sm all footprint with extended  
tem perature capabilities
