LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
Analog peripherals:
12-bit ADC with 12 input channels and with multiple internal and external trigger
inputs and sample rates of up to 5.0 MSamples/sec. The ADC supports two
independent conversion sequences.
Integrated temperature sensor connected to the ADC.
DMIC subsystem including a dual-channel PDM microphone interface, flexible
decimators, 16 entry FIFOs, optional DC locking, hardware voice activity detection,
and the option to stream the processed output data to I
2
S.
Timers:
Five 32-bit standard general purpose timers/counters, four of which support up to
four capture inputs and four compare outputs, PWM mode, and external count
input. Specific timer events can be selected to generate DMA requests. The fifth
timer does not have external pin connections and may be used for internal timing
operations.
One SCTimer/PWM with eight input and eight output functions (including capture
and match). Inputs and outputs can be routed to or from external pins and internally
to or from selected peripherals. Internally, the SCTimer/PWM supports ten
captures/matches, ten events, and ten states.
32-bit Real-time clock (RTC) with 1 s resolution running in the always-on power
domain. A timer in the RTC can be used for wake-up from all low power modes
including deep power-down, with 1 ms resolution.
Multiple-channel multi-rate 24-bit timer (MRT) for repetitive interrupt generation at
up to four programmable, fixed rates.
Windowed Watchdog Timer (WWDT).
Clock generation:
12 MHz internal Free Running Oscillator (FRO). This oscillator provides a
selectable 48 MHz or 96 MHz output, and a 12 MHz output (divided down from the
selected higher frequency) that can be used as a system clock. The FRO is
trimmed to
1 % accuracy over the entire voltage and temperature range.
External clock input for clock frequencies of up to 25 MHz.
Watchdog oscillator (WDTOSC) with a frequency range of 6 kHz to 1.5 MHz.
32.768 kHz low-power RTC oscillator.
System PLL allows CPU operation up to the maximum CPU rate without the need
for a high-frequency external clock. May be run from the internal FRO 12 MHz
output, the external clock input CLKIN, or the RTC oscillator.
Clock output function with divider.
Frequency measurement unit for measuring the frequency of any on-chip or
off-chip clock signal.
Power control:
Programmable PMU (Power Management Unit) to minimize power consumption
and to match requirements at different performance levels.
Reduced power modes: sleep, deep-sleep, and deep power-down.
Wake-up from deep-sleep modes due to activity on the USART, SPI, and I2C
peripherals when operating as slaves.
