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 Cortex^TM-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.
