LPC11E14FHN33/401,

The LPC11E1x 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 LPC11E1x operate at CPU frequencies of up to 50 MHz. The peripheral complement of the LPC11E1x includes up to 32 kB of flash memory, up to 10 kB of SRAM data memory and 4 kB EEPROM, one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 USART with support for synchronous mode and smart card interface, two SSP interfaces, four general-purpose counter/timers, a 10-bit ADC, and up to 54 general-purpose I/O pins.

• System:
  • ARM Cortex-M0 processor, running at frequencies of up to 50 MHz.
  • ARM Cortex-M0 built-in Nested Vectored Interrupt Controller (NVIC).
  • Non-Maskable Interrupt (NMI) input selectable from several input sources.
  • System tick timer.
• Memory:
  • Up to 32 kB on-chip flash program memory.
  • Up to 4 kB on-chip EEPROM data memory; byte erasable and byte programmable.
  • Up to 10 kB SRAM data memory.
  • 16 kB boot ROM including 32-bit integer divide routines and power profiles.
  • In-System Programming (ISP) and In-Application Programming (IAP) for flash and EEPROM via on-chip bootloader software.
• Debug options:
  • Standard JTAG test interface for BSDL.
  • Serial Wire Debug.
• Analog peripherals:
  • 10-bit ADC with input multiplexing among eight pins.
