***Oki Semiconductor Unveils New 32-Bit ARM MCUs
(February 10)

Oki Semiconductor today introduced three product additions to its
family of low-cost, 32-bit, general purpose microcontrollers
featuring ARM architecture. Oki's ML674001, ML67Q4002 and
ML67Q4003 are the latest in a series of ARM7 core-based offerings
on a 32-bit RISC microprocessor architecture, with 32-bit MCU
performance, geared to designers currently using proprietary 16-
bit technology.

Oki Semiconductor's goal is to make the ARM7 family of
microcontrollers the new standard for low-cost 16/32-bit MCU
design, much like the 8051 set the standard for 8-bit
architecture. Oki believes that their new ML674K series of MCU
solutions provides a better alternative to MCUs with proprietary
architecture. They stated that the ARM7 core used in these
products offers high performance, industry support, ready-to-use
software applications, and a selection of tools from third-party
vendors.

The ML674001, ML67Q4002 and ML67Q4003 feature the ARM7TDMI
architecture, uPlat-7B design platform, 32 KB of internal SRAM
memory, and a host of I/O peripherals, including 4 KB of internal
boot ROM. Additionally, the ML67Q4002 includes 256 KB of flash
memory, while the ML67Q4003 comes standard with 512 KB of flash.
The products are also pin-for-pin compatible with each other for
upgrade flexibility. A CPU evaluation board is available, along
with reference designs and schematics to facilitate the use of
these Oki MCUs.

Oki's ML674001, ML67Q4002 and ML67Q4003 are intended for a
variety of application areas, including industrial, consumer
electronics, biomedical and medical instrumentation, PC
peripherals and security appliance systems. Key features include:

-- 2 channel DMA controller
-- Industrial operating temperature of -40 to +85 degrees C
-- General purpose and watchdog timers
-- Analog to digital converters
-- Up to 33 MHz operating frequency
-- Multiple serial ports, including UART, SIO and I2C
-- Interface for external ROM (flash), SRAM, SDRAM, memory and IO
(4 banks)

The new Oki ML674K series of ARM core-based products was designed
based on Oki's uPlat -- a development and evaluation platform.
Oki claims it has realized reductions of 50 percent in
development times and engineering resources using uPlat.

Oki is targeting its ML674001, ML67Q4002 and ML67Q4003
microcontrollers at the $300 million 16-bit MCU market in North
America.

Oki Semiconductor's ML674001, ML67Q4002 and ML67Q4003 are
presently sampling. Production prices are expected to start at $5
for the ROM-less version in quantities of 10,000 units.
