Chapter 1: LPC111x/LPC11Cxx Introductory information
1.2 Features
• 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:
– On-chip flash programming memory for LPC1100, LPC1100L, and LPC1100C
series: 32 kB (LPC1114/LPC11C14), 24 kB (LPC1113), 16 kB
(LPC1112/LPC11C12), or 8 kB (LPC1111), 4kB (LPC1110).
– On-chip flash programming memory for LPC1100XL series: 8 kB (LPC1111), 16 kB
(LPC1112), 24 kB (LPC1113), 32 kB (LPC1114/203/303), 48 kB (LPC1114/323),
56 kB (LPC1114/333), 64 kB (LPC1115).
– 8 kB, 4 kB, 2 kB, or 1 kB SRAM.
– In-System Programming (ISP) and In-Application Programming (IAP) via on-chip
bootloader software.
– LPC1100XL series only: page erase IAP command.
• Digital peripherals:
– Up to 42 General Purpose I/O (GPIO) pins with configurable pull-up/pull-down
resistors. Number of GPIO pins is reduced for smaller packages and
LPC11C22/C24.
– 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 I

C-bus pins in Fast-mode Plus.
– Four general purpose timers/counters with a total of four capture inputs and up to
13 match outputs.
– Programmable WatchDog Timer (WDT).
• Analog peripherals:
– 10-bit ADC with input multiplexing among up to 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 packages only).
– I

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 (LPC11Cxx only). On-chip CAN and CANopen drivers included.
– On-chip, high-speed CAN transceiver (parts LPC11C22/C24 only).
• 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.
