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, 8 kB of data memory, one C_CAN controller, one Fast-mode Plus I2C-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.
- 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.
- 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(LPC11C12/C14) or 12 (LPC11C22/C24) match outputs.
