RS-232 Serial I/O Interface ASIC

Add RS-232 Serial I/O Ports to Your Product

The mobilityIC™ Dual Port or mDP (formerly HIS3) is a single chip implementation of two serial ports interfaced to the CompactFlash (CF) or PC Card bus. A single or dual serial port peripheral can be built with an mDP, a crystal, an EEPROM and two serial transceiver chips. Such a design offers PC Card/CF compliance, high performance, low power consumption and minimum component count.

The mDP uses a 16C550 compliant core with 512-byte FIFOs in expanded mode. The mDP connects directly to a serial EEPROM to store nonvolatile information which includes the PC Card/CF tuples and initial configuration information. Attribute memory consists of a 248-byte Card Information Structure (CIS), a 16-byte initialization area, and 15 Configuration Registers.

The mDP can be designed into a range of devices:

• Standard serial ports
• WAN cards
• Bar code scanners
• GPS products
• High-speed radios
• RFID readers
• Blood analyzers
• Other industrial applications

Powerful and Flexible Serial I/O Features

• Industry standard - supports a superset of the 16C550 PC Compatible Universal Asynchronous Receiver Transmitter (UART) which has become a standard for interfacing serial peripherals to computer systems.
  
  
• High performance – contains two UARTs with data rates up to 6.0 Mbps each. The deep FIFOs—512-byte deep receiver and transmitter FIFO memory—reduce the CPU overhead and allow higher data rates.
  
  
• Minimal power consumption – supports fully programmable clock division and sleep modes when a function is not being used. The mDP can operate at either 3.3 or 5 volts and does not require external regulation to operate in low or high voltage environments.
  
  
• Software support – device drivers available for Windows CE/9x/Me/2000/XP

Add RS-232 Serial I/O Ports with the mDP Dev Kit

Use the mobilityIC Dual Port (mDP) Dev Kit to add one or two serial I/O ports into your product. With the mDP Dev Kit, you utilize a development platform, technical documents and support tools to integrate the mDP ASIC into your device.

Dev Kit Contents

• mDP Development Board – has a fully operational 8-bit Compact-Flash interface. Tuples included with the Dev Kit can be downloaded to the on-board serial EEPROM to verify product performance.
• (5) mobilityIC Dual Port chips
  
  
• Dev Kit CD – includes schematics, a reference design, the mDP Specification, Dev Kit User’s Manual, high-speed serial drivers and Tuple Programmer software.
  
  
• Type-1 CF-to-PC Card adapter

Optional Module Mode Daughter Board

When the Module Mode board is mated to the main Development Board, the system demonstrates how two mDP chips can operate as four independent UARTs. When the Module Mode board is used in an embedded system, the mDP chip interfaces with the local bus of the embedded system and provides two UARTs.
