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.
