LPC11Cx2/Cx4 32-bit ARM Cortex-M0 microcontroller 16/32 kB flash, 8 kB SRAM C CAN Rev. 3.2 4 January 2016 Product data sheet 1. General description The LPC11Cx2/Cx4 are an ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The LPC11Cx2/Cx4 operate at CPU frequencies of up to 50 MHz. The peripheral complement of the LPC11Cx2/Cx4 includes 16/32 kB of flash memory, 2 8 kB of data memory, one C CAN controller, one Fast-mode Plus I C-bus interface, one RS-485/EIA-485 UART, two SPI interfaces with SSP features, four general purpose counter/timers, a 10-bit ADC, and up to 40 general purpose I/O pins. On-chip C CAN drivers and flash In-System Programming tools via C CAN are included. In addition, the LPC11C22 and LPC11C24 parts include an on-chip, high-speed CAN transceiver. 2. Features and benefits 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 (LPC11Cx4) or 16 kB (LPC11Cx2) on-chip flash program memory. 8 kB SRAM data memory. In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software. Flash ISP commands can be issued via UART or C CAN. Digital peripherals: General Purpose I/O (GPIO) pins with configurable pull-up/pull-down resistors. 40 GPIO pins on the LPC11C12/C14 parts 36 GPIO pins on the LPC11C22/C24 parts. GPIO pins can be used as edge and level sensitive interrupt sources. High-current output driver (20 mA) on one pin. 2 High-current sink drivers (20 mA) on two I C-bus pins in Fast-mode Plus. Four general purpose counter/timers with a total of four capture inputs and 13 (LPC11C12/C14) or 12 (LPC11C22/C24) match outputs. LPC11Cx2/Cx4 NXP Semiconductors 32-bit ARM Cortex-M0 microcontroller 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. 2 2 I C-bus interface supporting full I 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. On-chip C 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. 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, IRC, CPU clock, or 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 13 of the GPIO 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. 3.
