LPC1111/12/13/14

32-bit ARM Cortex-M0 microcontroller

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.
