Kinetis KL43 Microcontroller
48 MHz ARM® Cortex®-M0+ and 128/256 KB Flash
The KL43 series is optimized for cost-sensitive and battery-
powered applications requiring low-power USB connectivity and
segment LCD. The product offers:
• Low power segment LCD up to 24x8 or 28x4
• USB FS 2.0 device without requiring an external crystal
• Embedded ROM with boot loader for flexible program
upgrade
• High accuracy internal voltage and clock reference
• FlexIO to support any standard and customized serial
peripheral emulation
• Down to 54uA/MHz in very low power run mode and
1.96uA in deep sleep mode (RAM + RTC retained)
