Nové procesory spoločnosti NXP - LPC1111/12/13/14, pracujú s jadrom ARM Cortex-M0.
Sú taktované frekvenciou až do 50 MHz. Ich periférie obsahujú až 32 kB Flash pamäte, až 8 kB RAM pamäte, rozhranie Fast-mode Plus I²C- bus, UART RS-485/EIA-485, dve SPI rozhrania s vlastnosťami SSP, štyri časovače/čítače, 10-bitový ADC a až 42 GPIO pinov.

Vlastnosti

• System:
  - ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
  - ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
  - Serial Wire Debug.
  - System tick timer.
  
• Memory:
  - 32 kB (LPC1114), 24 kB (LPC1113), 16 kB (LPC1112), or 8 kB (LPC1111) on-chip flash programming memory.
  - 8 kB, 4 kB, or 2 kB SRAM.
  - In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
  
• Digital peripherals:
  - Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors.
  - GPIO pins can be used as edge and level sensitive interrupt sources.
  - High- current output driver (20 mA) on one pin.
  - High- current sink drivers (20 mA) on two I²C- bus pins in Fast-mode Plus.
  - Four general purpose counter/timers with a total of four capture inputs and 13 match outputs.
  - Programmable WatchDog Timer (WDT).
  
• Analog peripherals:
  - 10-bit ADC with input multiplexing among 8 pins.
  
• Serial interfaces:
  - UART with fractional baud rate generation, internal FIFO, and RS-485 support.
  - Two SPI controllers with SSP features and with FIFO and multi-protocol capabilities (second SPI on LQFP48 and PLCC44 packages only).
  - I²C- bus interface supporting full I²C- bus specification and Fast-mode Plus with a data rate of 1 Mbit/s with multiple address recognition and monitor mode.
  
• Clock generation:
  - 12 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as a system clock.
  - Crystal oscillator with an operating range of 1 MHz to 25 MHz.
  - Programmable watchdog oscillator with a frequency range of 7.8 kHz to 1.8 MHz.
  - 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 internal RC oscillator.
  - Clock output function with divider that can reflect the system oscillator clock, IRC clock, CPU clock, and the Watchdog clock.
  
• Power control:
  - Integrated PMU ( Power Management Unit) to minimize power consumption during Sleep, Deep-sleep, and Deep power-down modes.
  - Three reduced power modes: Sleep, Deep-sleep, and Deep power-down.
  - Processor wake-up from Deep-sleep mode via a dedicated start logic using up to 13 of the functional pins.
  - Power-On Reset (POR).
  - Brownout detect with four separate thresholds for interrupt and forced reset.
  
• Unique device serial number for identification.
  
• Single 3.3 V power supply (1.8 V to 3.6 V).
  
• Available as 48-pin LQFP package, 33-pin HVQFN package, and 44-pin PLCC package.
