Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

ML674001/Q4002/Q4003
32-bit ARM-Based General-Purpose Microcontroller
FEDL674001-01
Issue Date: Dec. 15, 2003
GENERAL DESCRIPTION
The ML674001, ML67Q4002, and ML67Q4003 microcontrollers (MCUs) are the members of an extensive and
growing family of 32-bit ARM
®
-based standard products for general-purpose applications that require 32-bit
CPU performance and low cost afforded by MCU integrated features.
ML674001/67Q4002/67Q4003 provide built-in 32Kbyte SRAM, built-in 4Kbyte boot ROM, and a host of other
useful peripherals such as auto-reload timers, watchdog timer (WDT), pulse-width modulators (PWM), A-to-D
converter, expanded UARTs, synchronous serial port, I2C serial interface, GPIOs, DMA controller, external
memory controller, and boundary scan capability. In addition, the ML67Q4002 and ML67Q4003 offer 256
Kbytes and 512 Kbytes of built-in Flash memory respectively. The ML674001, ML67Q4002 and ML67Q4003
are pin-to-pin compatible with each other for easy performance updates.
Oki’s ML674K Family MCUs are capable of executing both the 32-bit ARM instruction set for
high-performance applications as well as the 16-bit Thumb
®
instruction set for high code-density,
power-efficient applications. With an ARM7TDMI
®
core operating at 33 MHz maximum frequency, ARM
Thumb™ capabilities, and robust feature sets, the ML674001 Series MCUs are suitable for an array of
applications including high performance industrial controllers and instrumentation, telecom, PC peripherals,
security/surveillance, test equipment, and a variety of consumer electronics devices.
The ARM7TDMI
®
Advantage
Oki’s ML674K Family of low-cost ARM-based MCUs offers system designers a bridge from 8- and 16-bit
proprietary MCU architectures to ARM’s higher-performance, affordable, widely-accepted industry standard
architecture and its industry-wide support infrastructure. The ARM industry infrastructure offers the system
developers many advantages including software compatibility, many ready-to-use software applications, large
choices among hardware and software development tools. These ARM-based advantages allow Oki’s
customers to better leverage engineering resources, lower development costs, minimize project risks, and reduce
their product time to market. In addition, migration of a design with an Oki standard MCU to an Oki custom
solution is easily facilitated with its award-winning uPLAT™ product development architecture.
