LPC540xx
NXP Semiconductors
32-bit ARM Cortex-M4 microcontroller
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.
Ultra-low power Micro-tick Timer, running from the Watchdog oscillator that can be
used to wake up the device from low power modes.
Power-On Reset (POR).
Brown-Out Detect (BOD) with separate thresholds for interrupt and forced reset.
Single power supply 1.71 V to 3.6 V.
Power-On Reset (POR).
Brown-Out Detect (BOD) with separate thresholds for interrupt and forced reset.
JTAG boundary scan supported.
128 bit unique device serial number for identification.
Operating temperature range 40 °C to +105 °C.
Available in TFBGA180, TFBGA100, LQFP208, and LQFP100 packages.
