NXP LPC15xx系列MCU马达控制方案

 32 kHz low-power RTC oscillator with 32 kHz, 1 kHz, and 1 Hz outputs.
 System PLL allows CPU operation up to the maximum CPU rate without the need　for a high-frequency crystal. May be run from the system oscillator or the internalRC oscillator.
 Two additional PLLs for generating the USB and SCTimer/PWM clocks.
 Clock output function with divider that can reflect the crystal oscillator, the mainclock, the IRC, or the watchdog oscillator.
 Power control:
 Integrated PMU (Power Management Unit) to minimize power consumption.
 Reduced power modes: Sleep mode, Deep-sleep mode, Power-down mode, and
Deep power-down mode.
 APIs provided for optimizing power consumption in active and sleep modes and for configuring Deep-sleep, Power-down, and Deep power-down modes.
 Wake-up from Deep-sleep and Power-down modes on activity on USB, USART,
SPI, and I2C peripherals.
 Wake-up from Sleep, Deep-sleep, Power-down, and Deep power-down modes
from the RTC alarm or wake-up interrupts.
 Timer-controlled self wake-up from Deep power-down mode using the RTC
high-resolution/wake-up 1 kHz timer.
 Power-On Reset (POR).
 BrownOut Detect BOD).
 JTAG boundary scan modes supported.
 Unique device serial number for identification
 Single power supply 2.4 V to 3.6 V.
 Temperature range 40 ℃ to +105 ℃.
 Available as LQFP100, LQFP64, and LQFP48 packages.
