• Manufacturer: Oki Semiconductor

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
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
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.
