Oki Rolls Out Three New Low-cost, ARM-based Microcontrollers

4/15/2003 - Oki Semiconductor, a leading technology partner for the new era of digital communications and convergence, announced the addition of three new product offerings to its growing line of ARM® core-based microprocessors targeted at embedded designers seeking low-cost 32-bit MCU performance. Based on the ARM7TDMI® core, Oki's ML675001, ML67Q5002 and ML67Q5003are general-purpose microcontrollers ideally suited for a range of applications including industrial, consumer electronics, biomedical and medical instrumentation, PC peripherals and security appliance systems.

The new ML675K series provides higher performance and more advanced features at a lower price than comparable microcontrollers. Among these high-performance features are an internal unified cache, 32 KB of high speed RAM, and an operating frequency of up to 60 MHz. All three products in the ML675K series are pin-for-pin compatible with each other and with Oki's ML674K MCU series announced earlier this year. Designs with the ML674K MCUs can be upgraded to a higher performance ML675K series microcontroller without changing the layout of the CPU board, thereby preserving all of the original hardware investment.

Oki's expanding line of ARM core-based solutions is designed to bring ARM technology to the broader embedded market. The Oki product family based on an ARM7TM core represents an affordable, but highly superior alternative to proprietary MCU designs, offering 32-bit performance, complete industry support, more out-of-the-box software applications, and a wide selection of system development tools from qualified third-party vendors. "Today's announcement continues Oki's momentum in the 32-bit ARM MCU arena and provides a competitive offering to designers looking for higher performance than that available from 16-bit MCU solutions, without a cost premium," said Mitchell Le, senior product marketing manager of MCU products, Oki Semiconductor. "This latest series of MCUs exemplifies Oki's ongoing commitment to the ARM architecture evidenced in earlier product announcements. Products resulting from our relationship with ARM provide Oki's customers with a risk-free alternative to proprietary architecture solutions, access to a wide variety of ARM development tools, and the advantages of industry infrastructure support for the leading RISC architecture."

"Oki's new ML675K product family is a solid antidote to the continuing need for greater flexibility and functionality in the MCU market," said John Sharp, microcontroller segment manager, ARM. "Oki's expanded product line provides OEM's with a swift and easy migration path from an 8- and 16-bit MCU to a high-performance 32-bit architecture."

Like the ML674K series, Oki's ML675001, ML67Q5002 and ML67Q5003 offer 32 KB of internal SRAM memory and a range of useful I/O peripherals, including 4 KB of internal boot ROM. Additionally, the ML67Q5002 includes 256 KB of flash memory while the ML67Q5003 comes standard with 512 KB of Flash ROM. Key features include:

Price and Availability
Oki Semiconductor's ML675001, ML67Q5002 and ML67Q5300 are presently sampling. Production prices are expected to start at less than $5 for the ROM-less version in quantities of 100,000.
