LPC5410x

32-bit ARM Cortex-M4/M0+ microcontroller

7.18.6.1 Features

• 48-bit counter running from the main clock. Counter can be free-running or be reset

by a generated interrupt.

• 48-bit compare value.

• 48-bit compare mask. An interrupt is generated when the counter value equals the

compare value, after masking. This allows for combinations not possible with a simple

compare.

7.18.7 Micro-tick timer (UTICK)

The ultra-low power Micro-tick Timer, running from the Watchdog oscillator, can be used

to wake up the device from low power modes.

7.18.7.1 Features

• Ultra simple timer.

• Write once to start.

• Interrupt or software polling.

7.19 12-bit Analog-to-Digital Converter (ADC)

The ADC supports a resolution of 12-bit and fast conversion rates of up to 5.0

Msamples/s. Sequences of analog-to-digital conversions can be triggered by multiple

sources. Possible trigger sources are the SCT, external pins, and the ARM TXEV

interrupt.

The ADC supports a variable clocking scheme with clocking synchronous to the system

clock or independent, asynchronous clocking for high-speed conversions

The ADC includes a hardware threshold compare function with zero-crossing detection.

The threshold crossing interrupt is connected internally to the SCT inputs for tight timing

control between the ADC and the SCT.

7.19.1 Features

• 12-bit successive approximation analog to digital converter.

• Input multiplexing among up to 12 pins.

• Two configurable conversion sequences with independent triggers.

• Optional automatic high/low threshold comparison and “zero crossing” detection.

• Measurement range VREFN to VREFP (typically 3 V; not to exceed VDDA voltage

level).

• 12-bit conversion rate of 5.0 MHz. Options for reduced resolution at higher conversion

rates.
