General description
The LPC15xx are ARM Cortex-M3 based microcontrollers for embedded applications featuring a rich peripheral set with very low power consumption. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration.
The LPC15xx operate at CPU frequencies of up to 72 MHz. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching.
The LPC15xx includes up to 256 kB of flash memory, 32 kB of ROM, a 4 kB EEPROM, and up to 36 kB of SRAM. The peripheral complement includes one full-speed USB 2.0 device, two SPI interfaces, three USARTs, one Fast-mode Plus I2C-bus interface, one C_CAN module, PWM/timer subsystem with four configurable, multi-purpose State Configurable Timers (SCTimer/PWM) with input pre-processing unit, a Real-time clock module with independent power supply and a dedicated oscillator, two 12-channel/12-bit, 2 Msamples/s ADCs, one 12-bit, 500 kSamples/s DAC, four voltage comparators with internal voltage reference, and a temperature sensor. A DMA engine can service most peripherals.
For additional documentation related to the LPC15xx parts, see Section 17 “References”.

event-driven timing and PWM applications.
◆ SCT Input Pre-processor Unit (SCTIPU) for processing timer inputs
and immediate handling of abort situations.
◆ Integrated with ADC threshold compare interrupts, temperature sensor,
and analog comparator outputs for motor control feedback using analog signals.
■ 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. (Continue ...)
