HMS91C7432

Hynix semiconductor 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. 1 Hynix semiconductor HMS91C7432 features and functions z z z z z z z z z z z z Implementation of the complete TCP/IP protocol suite Built-in Email sending and reception function.
