32-Bit ARM
®
-Based General Purpose Microcontroller
ML67Q4050/Q4060 Series
64KBytes or 128KBytes of 32-bit wide zero-wait state
FLASH memory and 16KBytes of SRAM. The devices
also contain multiple serial interfaces, like I

S,
SPI, and UARTs (supporting 9-bit communications),
along with many other peripheral functions.
• SIO
- Full duplex operation with built in baud rate generator
DESCRIPTION
The Oki ML67Q4050/Q4060 Series of microcontrollers
have been added to Oki's growing family of ARM
based microcontrollers. These devices are the world's
smallest packaged ARM processors. They contain a
