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 FFFP Film Forming Fluoroprotein Foam

FFFP Family Fun Fitness Pad (Nintendo) and M38049FFSP FFSP Full Function Signal Processor . Unlike the industry's previous generations of MCUs with EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. 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 (1) (MicroController Unit) A computer on a single chip. See microcontroller.
(2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users 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."
Based on Mitsubishi's 740 Family CPU CPU

Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. 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 (1) See A/D converter.
(2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. ). 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 See D/A converter and discretionary access control.
DAC - Digital to Analog Converter )
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 (Universal Asynchronous Receiver Transmitter) The electronic circuit that makes up the serial port. Also known as "universal serial asynchronous receiver transmitter" (USART), it converts parallel bytes from the CPU into serial bits for transmission, and vice ports on the
M38039FFFP, along with an I2C serial port on the M38049FFSP,
provide I/O flexibility.
-- An 8-bit pulse width modulation See PWM. (PWM) output can be used for
motor speed control in applications ranging from printers and
scanners to traction devices.
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 See IDE.
