NXP LPC15xx系列MCU马达控制方案

 Special-application and simple timers:
 24-bit, four-channel, multi-rate timer (MRT) for repetitive interrupt generation at up to four programmable, fixed rates.
 Repetitive interrupt timer for general purpose use.
 Windowed Watchdog timer (WWDT).
 High-resolution 32-bit Real-time clock (RTC) with selectable 1 s or 1 ms time resolution running in the always-on power domain. RTC can be used for wake-up from all low power modes including Deep power-down.
 Analog peripherals:
 Two 12-bit ADC with up to 12 input channels per ADC and with multiple internal and external trigger inputs and sample rates of up to 2 Msamples/s. Each ADC supports two independent conversion sequences. ADC conversion clock can be the system clock or an asynchronous clock derived from one of the three PLLs.
 One 12-bit DAC.
 Integrated temperature sensor and band gap internal reference voltage.
 Four comparators with external and internal voltage references (ACMP0 to 3).Comparator outputs are internally connected to the SCTimer/PWMs and ADCs and externally to pins. Each comparator output contains a programmable glitch filter.
 Serial interfaces:
 Three USART interfaces with DMA, RS-485 support, autobaud, and with
synchronous mode and 32 kHz mode for wake-up from Deep-sleep and
Power-down modes. The USARTs share a fractional baud-rate generator.
 Two SPI controllers.
 One I2C-bus interface supporting fast mode and Fast-mode Plus with data rates of up to 1Mbit/s and with multiple address recognition and monitor mode.
 One C_CAN controller.
 One USB 2.0 full-speed device controller with on-chip PHY.
 Clock generation:
 12 MHz internal RC oscillator trimmed to 1 % accuracy for 25 C Tamb +85 Cthat can optionally be used as a system clock.
 Crystal oscillator with an operating range of 1 MHz to 25 MHz.
 Watchdog oscillator with a frequency range of 503 kHz.
