Description

Oki's ML674000 standard microcontroller (MCU) is a member of an extensive and growing family of ARM® architecture 32-bit MCUs for general-purpose applications that require 32-bit CPU performance and low cost afforded by MCU integrated features.

Oki Semiconductor's ML674000 MCU provides a host of useful peripherals such as 8KB of on-board SRAM, timers, watchdog timer, pulse-width modulators, AD converter, UART's, GPIO connectivity capability, and external memory controller. These integrated features make it ideal for embedded applications where low costs and low power consumption are key.

Oki's ML674K series 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 power-efficient applications. With an ARM7TDMI® core operating at 33 MHz maximum frequency, ARM Thumb™ capabilities, and robust feature sets, the ML674K 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 Semiconductor's ML67 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 system developers many advantages including software compatibility, many ready-to-use software applications, and a large choice 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 µPLAT™ product development architecture.
