Available in a Wafer-level Chip Size Package That is Less Than 25 Square
Millimeters, Oki's ML67406x Series is the World's Smallest ARM-based
Microcontroller
EMBEDDED SYSTEMS CONFERENCE, SAN FRANCISCO, March 7 /PRNewswire/ -- Oki
Semiconductor, a leading technology partner for the new era of digital
communications and convergence, today announced the world's smallest packaged
ARM processor as part of its introduction of two new series of low-power
ARM7-based general-purpose microcontrollers (MCUs). An expansion of its
Advantage Microcontroller(TM) products, Oki's ML67406x (406x) series provides
system designers with a unique combination of a small footprint, low power
requirements, legacy 8- and 16-bit support, and a broad set of serial
communications interfaces that can be easily integrated into a wide array of
applications.
The 406x MCUs are available in an extremely small wafer-level chip size
package (WCSP) version, occupying less than 25 square millimeters, which meets
the small form factor design requirements of product designers for a broad set
of consumer, medical, and industrial applications where board space is
limited. The miniature size of the 406x WCSP takes advantage of Oki's
advanced packaging technology by providing a packaged part with a footprint no
larger than the die itself, enabling designers to develop extremely compact
consumer, industrial and medical devices. The new 406x series along with the
companion ML67405x (405x) series of Advantage Microcontrollers are very
versatile, with a unique combination of communications support, including
Multi-Master I2C, SPI, I2S, and 9-bit UARTs enabling communications with
legacy 8-bit MCU devices. The 405x series adds an external bus or 68 GPIO
pins to the 406x series for use in systems that require extra functionality.
"The WCSP technology and low-power advantages of the new 406x series are
the latest product advancements in Oki's expanding portfolio of 32-bit ARM
MCUs and represents our continued commitment to the ARM architecture," said
David Pelavin, director of marketing at Oki Semiconductor. "With a
significant investment in ARM core products, applications, and design
philosophy, Oki is committed to providing standard general purpose and
application specific solutions to support a growing set of markets that are
taking advantage of the benefits offered by the ARM MCU architecture."
Based on a 32-bit ARM7TDMI(R) MCU core running at 33 MHz, Oki's 405x and
406x series include MCUs ranging from 64K to 128K of 32-bit zero-wait state
flash memory and 16K of SRAM. The 405x and 406x offer power modes that meet a
broad set of system requirements for portable and fixed products. Running on
a 2.5V core power supply, the two Advantage Microcontroller devices enable
designers to take advantage of low power, low system cost, and readily
available 2.5V parts. The 405x and 406x MCUs can run from single or dual
power supplies. Package options are 64 or 144 pin LQFP, an 84 pin LFBGA or
64 pin WCSP.
The 405x and 406x series build on the success of Oki's growing line of
ARM-based Advantage Microcontrollers, offering designers an industry-standard
MCU platform with strong industry support, including a constantly growing
number of off the shelf software applications, and a wide variety of tools and
software from third-party vendors. Oki's Advantage Microcontrollers provide
customers with a more comprehensive feature set, greater ease and flexibility
of integration, and the performance required for today's demanding
applications. Engineering samples and a demo kit for the 405x and 406x
Advantage Microcontroller series will be available in the second quarter of
2005.
