mbed LPC1114FN28

The LPC1114FN28 is an ARM Cortex-M0 based, low-cost 32-bit MCU, 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 mbed LPC1114FN28 operates at CPU frequencies of 48 MHz. The LPC1114FN28 includes up to 32 kB of flash memory, up to 4 kB of data memory, one Fastmode Plus I2C-bus interface, one RS-485/EIA-485 UART, one SPI interface with SSP features, four general purpose counter/timers, a 10-bit ADC, and up to 22 general purpose I/O pins.

Note: LPC1114FN28 platform doesn't support RTOS due to its flash size. Please do not import mbed-rtos library into your project.




The LEDs on this pinout picture were not implemented on the mbed LPC1114FN28 board. The LED on the board is an indicator for mbed interface.

Available Packages

It is made particularly unique by the fact that it is available in a 28-pin dual-in-line package, making it perfect for breadboarding, and/or replacing 8 bit micro-controllers that you may have used just because they are available in a DIP package. As well as this, many different development boards are available for the LPC1114, for example an LPCXpresso, a board from Keil as well as from other companies.
