LPC15xx

32-bit ARM Cortex-M3 microcontroller

 ROM API support:

 Boot loader with boot options from flash or external source via USART, C_CAN, or

USB

 USB drivers

 ADC drivers

 SPI drivers

 USART drivers

 I2C drivers

 Power profiles and power mode configuration with low-power mode configuration

option

 DMA drivers

 C_CAN drivers

 Flash In-Application Programming (IAP) and In-System Programming (ISP).

 Digital peripherals:

 Simple DMA engine with 18 channels and 20 programmable input triggers.

 High-speed GPIO interface with up to 76 General-Purpose I/O (GPIO) pins with

configurable pull-up/pull-down resistors, open-drain mode, input inverter, and

programmable digital glitch filter.

 GPIO interrupt generation capability with boolean pattern-matching feature on eight

external inputs.

 Two GPIO grouped port interrupts.

 Switch matrix for flexible configuration of each I/O pin function.

 CRC engine.

 Quadrature Encoder Interface (QEI).

 Configurable PWM/timer/motor control subsystem:

 Up to four 32-bit counter/timers or up to eight 16-bit counter/timers or combinations

of 16-bit and 32-bit timers.

 Up to 28 match outputs and 22 configurable capture inputs with input multiplexer.

 Up to 28 PWM outputs total.

 Dither engine for improved average resolution of pulse edges.

 Four State Configurable Timers (SCTimers) for highly flexible, 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.
