Mitsubishi's New General-Purpose 8-bit Microcontrollers Use On-Chip Flash to Make Applications Field-Reprogrammable.

SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 28, 1999--

16.8-MHz Speed, Small Footprint, and Array of On-Chip Peripherals

Provide Flexibility for Consumer and Industrial Applications

Responding to market acceptance of its initial offerings of 8- and 16-bit microcontrollers (MCUs) with embedded NOR flash memory, the Electronic Device Group of Mitsubishi Electronics America Inc. today announced two new 8-bit embedded-flash microcontrollers, the M38039FFFP and M38049FFSP. Unlike the industry's previous generations of MCUs with EEPROM or flash, which were essentially development vehicles for mask-programmed production parts, Mitsubishi's chips are aimed at applications that require in-the-field reprogrammability.

On-chip flash memory enables customers to easily reprogram code or lookup tables. This makes it possible, for example, for parking meter manufacturers to achieve economies of scale by building a single system board that customers can reprogram depending on where and when meters are installed. Other application areas that can benefit from reprogrammability include consumer electronics (customizable climate control, multimedia entertainment), office automation (fax machines that call for their own service needs), and industrial control equipment that can be updated with new process recipes.

The M38039FFFP and M38049FFSP feature a smaller footprint than their 8-bit predecessors, which allows more compact system designs. Typical power dissipation during normal 5-volt operation is 60 mW at 16.8 MHz. Like Mitsubishi's earlier offerings, they continue to offer ample (60-Kbyte) reprogrammable flash memory and 2 Kbytes of on-board RAM.

"The general-purpose M38039FFFP and M38049FFSP extend Mitsubishi's flash-enabled 8-bit MCU product line to serve a more diverse user base of embedded designers than previous chips," said Jack Sardegna, director of microcontroller product marketing at Mitsubishi Electronics America. "These new microcontrollers provide our customers with the necessary speed, in-circuit programmability, enhanced standard features and reduced footprint architecture to enable leading-edge multimedia, industrial and commercial applications."

Enhanced Flexibility

Based on Mitsubishi's 740 Family CPU architecture, the new flash-enabled microcontrollers include a number of on-chip capabilities that make it easier and faster for engineers to develop applications for the industrial, commercial and consumer markets.

-- Nine external interrupts facilitate multitasking, enabling

applications to respond to a large number of external events.

-- The CPU core can select among 16 channels for input to the chips'

10-bit analog-to-digital converter (ADC). If not required for the

ADC, these inputs can be employed for digital data. (There are 71

programmable I/O ports.)

-- An on-chip, two-channel, 8-bit digital-to-analog converter (DAC)

allows developers to output audio and other analog signals.

-- An 8-segment LED direct-drive port on-chip enables developers to

implement optical readouts with minimal external logic.

-- Synchronous and synchronous/asynchronous UART ports on the

M38039FFFP, along with an I2C serial port on the M38049FFSP,

provide I/O flexibility.

-- An 8-bit pulse width modulation (PWM) output can be used for

motor speed control in applications ranging from printers and

scanners to traction devices.

Development Tools

Mitsubishi supplies customers with software tools for program development of its 8-bit microcontrollers. Customers develop software using Mitsubishi's PC4701HS in-circuit hardware emulator, which comes with the PD38 Windows(r) based debugger, emulation pod (M380000TL2-FPD) and device (M38049RFS).

Developers write software in assembly language by using Mitsubishi's SRA74 Assembler or in C language by using the IAR Embedded Workbench for 740 (EW740) from IAR Systems, which comes with IAR Systems' optimized C compiler and a fully integrated development environment. Advanced Transdata and BP Microsystems are developing flash programmers for the M38039FFFP and M38049FFSP microcontrollers.

Packaging, Availability and Pricing

The M38039FFFP and M38049FFSP are offered in 64-pin shrink dual in-line package (SDIP) packaging as well as 0.5-mm pitch (10-mm x 10-mm footprint) and 0.8-mm pitch (14-mm x 14-mm footprint) quad flat packs (QFPs).

Samples are available now and volume production is scheduled for the fourth quarter of 1999. The M38039FFFP is priced at $13 each in 10,000-unit quantities. The M38049FFSP, featuring the I2C bus, is priced at $14 each in 10,000-unit quantities.
