Chapter 1: LPC111x/LPC11C1x Introductory information
• 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).
– I
2
C-bus interface supporting full I
2
C-bus specification and Fast-mode Plus with a
data rate of 1 Mbit/s with multiple address recognition and monitor mode.
– C_CAN controller (LPC11C12/C14 only). On-chip CAN and CANopen drivers
included.
• 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.
