Mitsubishi ChipConnect Development Hardware Simplifies 8-Bit MCU Embedded Internet Designs.

SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 27, 1999--

Mitsubishi Electronics America's Electronic Device Group today announced ChipConnect(tm) development hardware and software for its low-cost, 8-bit Slim740 (M37531) microcontroller (MCU). This is a new addition to the ChipConnect family, launched in July with the 16-bit remote reprogrammable flash M16C ChipConnect Software Developers Kit (SDK). The Slim740 is already a popular choice for cost-sensitive applications such as remote control units, PDAs, white-good appliances and security applications. By using the EMIT(r) (Embedded Micro Internetworking Technology(tm) ) architecture developed by emWare(r), Inc., systems designers can now make Slim740-based products that are network enabled and accessible via an Internet Web browser or other interfaces.

"Mitsubishi has a reputation for providing quality consumer electronics," said Dr. Brian Sackett, strategic systems marketing manager at Mitsubishi Electronics America. "The benefits of collecting data and performing remote diagnostics over the Internet include major maintenance cost savings, the ability to easily analyze user trends, and increased customer satisfaction. With ChipConnect, these benefits can be realized in a variety of consumer and industrial systems."

"The barrier has been that cost is the critical factor in the appliance and controller markets," Sackett continued. "By using emWare's EMIT software, we can Internet enable the 8-bit MCU that is already the controller for that appliance. The Slim740 has proven itself for flexibility and long battery life in the realm of low-cost, low-power applications. By adding emWare's EMIT software at a low incremental cost, Mitsubishi has further extended the Slim740's value and utility."

EMIT device-networking software connects 8- and 16-bit MCU based appliances and controllers without requiring an RTOS or a TCP/IP stack in the device. At the core of emWare's EMIT distributed networking architecture is emMicro(tm), emGateway (tm), and the EMIT Access Library, which provide a complete and flexible device-to-user solution. The emMicro networking software component is a tiny device object server that resides on the microcontroller or microprocessor of the device and uses as little as 1K of space.

emMicro works with emGateway, which bridges large, conventional networks, including LANs, WANs, intranets and the Internet, to lightweight device networks, such as RS232, RS485, Ethernet, IR and RF. emGateway can reside on a PC, single-board computer. The interface can be a standard Web browser using JavaBean objects, a spreadsheet using Activex, or a PDA, phone, database or enterprise application.

Mitsubishi's embedded-Internet evaluation hardware consists of two reference-design/demo boards, plus a mini-emulator for the mask ROM/one-time programmable Slim740. Software tools consists of IAR's compiler and debugger, and a 60-day evaluation version of emWare's EMIT.

The basic Slim740 ChipConnect board contains a socket for a Slim740 MCU and a header for attaching Mitsubishi's mini emulator. Various switches and a potentiometer across the positive voltage supply - to simulate a signal applied to the Slim740's analog-to-digital converter (ADC) - serve as input devices, and a red, yellow, and green LED array demonstrates output (the Slim740 can drive LEDs directly). The Light & Sound Add-On Board plugs into headers on the basic board and provides a four-digit alphanumeric display as well as audio circuitry with a speaker.

The development board has been designed for the 36-lead SSOP version of the Slim740. The chip is also available in 32-lead DIP and TQFP packaging.

About the Slim740

The Slim740 (M37531) is a single-chip 8-bit microcontroller based on Mitsubishi's 740 Family CPU architecture. It combines an ultra-low-power CPU with peripheral functions that make it ideal for consumer products such as television remote controls, appliances, telephones, thermostats, and industrial controllers. It features a successive-approximation ADC with 10-bit resolution, y 1 least significant bit (LSB) absolute accuracy (typical), and eight analog input channels. There are three 8-bit timers and one 16-bit watchdog timer available; all four are multi-purpose. Designers can choose among timer, event count, pulse output, or pulse-period measurement modes, and select between two different clocks as the count source. There are two 8-bit by-1 serial I/O channels: one is a UART interface, and one is clock-synchronous. An LED drive port can drive 15 mA to a 7-segment device (or to multiple 7-segment devices with an external multiplexer).

The chip requires only 40 mW at 8 MHz and 5 V, and 1.1 mW at 2 MHz and low voltage (2.2 V). There are eight key-on wake-up channels available to enable applications to detect input keystrokes to shift the chip out of low-power consumption modes.

Availability

The ChipConnect Slim740 development board and software will be demonstrated in Mitsubishi's booth (Booth No. 1728) at the Embedded Systems Conference. Commercial availability is scheduled for December 1999. For further information, please visit http://www.mitsubishichips.com/chipconnect .
