The ML675001, ML67Q5002, and ML67Q5003 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. ML675001/67Q5002/67Q5003 provide 8KB unified cache memory, 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 ML67Q5002 and ML67Q5003 offer 256 Kbytes and 512 Kbytes of built-in Flash memory respectively. The ML675001, ML67Q5002 and ML67Q5003 are pin-to-pin compatible with each other, and are pin-to-pin compatible with ML674001 Series for easy performance updates. Oki's ML675K 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 60 MHz maximum frequency, ARM ThumbTM capabilities, and robust feature sets, the ML675001 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.
