ML630Q464/Q466
Ultra Low Power 32-bit Microcontroller
FEDL630Q464-01
Issue Date: Oct. 26, 2016
■ GENERAL DESCRIPTION
This LSI is a high-performance low power 32-bit microcontroller. Equipped with a 32-bit CPU core CortexTM-M0+, it
implements a 128 KB flash memory, 16 KB RAM, rich peripheral circuits, such as USB Full speed device, synchronous serial
port, UART, I2C bus interface, supply voltage level detect circuit, RC oscillation type A/D converter, successive approximation
type A/D converter, and LCD driver. The Flash ROM that is installed as program memory achieves low-voltage low-power
consumption operation (read operation) is most suitable for battery-driven applications.
■ FEATURES
