LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
[1] Measured on typical silicon samples with a 2 kHz input signal and overdrive < 100 V. Power switched off
to all analog peripherals except the comparator.
13. Application information
13.1 Suggested USB interface solutions
Remark: The USB controller is available as a device/Host/OTG controller on parts
LPC4088 and LPC4078/76 and as device-only controller on parts LPC4074/72.
