INTRODUCTION
From now on, you can hook your product onto the inter-net directly.
Put the PC aside, HMS91C7432 do all the jobs that the PC do for
inter-net connection.
HMS91C7432 is a CMOS IC with a complete TCP/IP protocol suite to facilitate
inter-net connection for embedded application. The built-in email engine can
transform any ASCII message to standard email format. It sends and receives
email; conduct the whole log on process automatically. Built-in PPP protocol
handle user-ISP handshaking and authentication process automatically. The
HMS91C7432 also includes the MODEM driver, no code should write to drive
the MODEM (parameter of modem must be transferred by the host to make
HMS91C7432 works with your modem).
Using HMS91C7432 is easy, a simple 8 bit parallel port (8 bit data plus 4 control
lines) bridge the IC with your application. A serial DTE port is ready for directly
connect to an onboard modem or through DTE interface to a serial modem.
Make your product inter-net able, just add an HMS91C7432 on your BOM.

Detail description of HMS91C7432 function and its application
TCP/IP protocol suite is the key to inter-net
access. Email; Home Page materials and all
the data traffic on the inter-net are carry out
by using the TCP/IP well defined format.
Time before HMS91C7432 exist, most inter-
net connection were to be handled by the PC.
Hand held devices and equipments must be
attached to the PC to get access to the
inter-net. Now the era of "PC-free" inter-net
connection has come. With HMS91C7432,
you can make your product be able to send
and receive email; surf on the WWW and
even "TALK" to another device through the
inter-net, by just plugging the telephone line
onto it.
The core of the HMS91C7432 is a complete
TCP/IP protocol suite. Files and messages
pass to the HMS91C7432 will be transformed
into the appropriate format and packets to
conform the inter-net standard. This
transformation is transparent to the user's
application.
On top of the TCP/IP core, there is an Email
engine built-in. User's program just needed
to inform the HMS91C7432 an email is going
to send and follow with the email body.
HMS91C7432 will then wake up the modem
and dial the ISP to log on the mail server. The
mail will be sent when log on has success.
HMS91C7432 complete this whole process
fully automatic.
Reception of Email is as simple as getting
email on the PC. The application program
send a "Receive Email" command to the
HMS91C7432, it dial up the ISP and log on
the server, then it check and download any
email automatically. Each message will be
stored in the RAM buffer, HMS91C7432 will
notify the application program an email has
come and waiting for retrieve.
The built-in PPP module handles the "Log on
process". This is a standard protocol to pass
the user's account ID and the password to
the ISP. This module handles the
authentication and "Handshaking". User's
program just pass the user's ID and
password to HMS91C7432 and the PPP do it
all.
HMS91C7432 (later version only) also equip
with a FTP module to facilitate file transfer
and file downloading from the FTP site. This
function is especially good for remote system
update and game download for hand-held
game inter-net access.
The standard serial DTE interface on the
HMS91C7432 ease the modem connection.
The built-in modem driver support V.90 and
56K flex dual modem or lower.
HMS91C7432 is controlled by an 8 bit
data/command port. This port accepts
command passed by the host MCU.
Incoming and outgoing message will be
passed between the host and the
HMS91C7432 through this port as well.

Specifications of HMS91C7432
The HMS91C7432 TCP/IP communication controller is manufactured in advance CMOS
process.
The HMS91C7432 implement complete TCP/IP protocol suite includes PPP; IP; ICMP;TCP;
UDP; DNS; SMTP; POP3 protocol and additionally a general MODEM driver.
The HMS91C7432 is built-in with 96Kb SRAM (12K x 8) for communication and buffering, A full
duplex UART as DTE for ease of serial modem connection.
The HMS91C7432 has an 8 bits Data/Command port and 4 control pins to facilitate control and
communication between the Host MCU and the modem. There are only 20 simple commands,
each of which is a single byte long, to establish and to complete the whole internet
communication. 45 respond codes for the Host MCU to monitor the communication status.
Extremely low external component count. Very low power consumption.

Example 4. HMS91C7432 request for missing connection info
When the HMS91C7432 is going to make a connection to the internet or to a mail server, it will
check if all necessary info is available. The connection info may be erased due to memory
overlaying. Upon an internet session is ended, HMS91C7432 will clear its memory pool for
another session. Whenever connection info is needed, HMS91C7432 will issue a request to the
host for such info. The request will be made using complex command mode with control code
0x01 followed by a Data ID as listed in Table 5.

Example 5. HMS91C7432 returning result code to the host
There are sets of Result Code coresponding to each command issued by the host to the
HMS91C7432. The HMS91C7432 returns at least one result code to each command, to report
the result of execution or the status of the connection. HMS91C7432 returns the result code by
using complex command mode with control code 0x02 followed by the result code (in the Data
ID field) as listed in Table 6.

Example 6. Host requesting Connection Status and the HMS91C7432 returns
User may make a request for the connection status at any time during the internet session. The
host may make its request by using Simple Command Mode with Control Code 0x04. The
HMS91C7432 will return the connection status by Complex Command Mode with Control Code
0x03 followed by the connection status code as listed in Table 7.
This example demonstrates how the host makes a connection status request and how the
HMS91C7432 responds to this request. The host made the request after a successful logon to
the POP3 server. The HMS91C7432 report that the system has logon to the POP3 server.

Example 7. Host requesting SMTP Connection Status and the HMS91C7432 returns
When sending out an email during SMTP session, the host should know when can it pass the
mail header and when can it pass the mail body to the HMS91C7432. Usually, depending on the
traffic of the network, it takes a longer time to be successfully logon to the SMTP server. The
host should frequently check the connection status to determine the time to pass the mail
header or to determine when to terminate the logon process if a time out is up. The host may
make such a report by using Simple Command Mode with Control Code 0x05. The
HMS91C7432 will return the SMTP connection status by Complex Command Mode with Control
Code 0x06 followed with the SMTP status code as listed in Table 8.
This example demonstrates how the host makes a SMTP connection status request and how
the HMS91C7432 responds to this request. The host made the request after a successful logon
to the SMTP server. The HMS91C7432 report that it is ready to accept the mail body. If the
request is made during the mail sending session, the following connection status indicates the
HMS91C7432 is ready to accept more packets (Outgoing buffer is not full).
