The LPC11U34FBD48/421 is a 32-bit Microcontroller based on ARM Cortex-M0 core with RISC architecture operates at a maximum frequency of 50MHz. The device incorporates 40kB internal flash, 10kB internal RAM, 4kB EEPROM, two SSP interfaces, four general purpose counters/timers, 8-channel 10-bit A/D converter with sample rates of up to 400ksps, full speed USB 2.0 device and 40 general-purpose I/O pins. This device also features peripherals like one RS-485/EIA-485 USART with support for synchronous mode and smart card interface, one inter-integrated circuit (I2C) and two serial peripheral interface (SPI) modules. It is offering low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures.

• ARM Cortex-M0 built-in nested vectored interrupt controller (NVIC)
• Non-maskable interrupt (NMI) input selectable from several input sources
• System tick timer
• In-system programming (ISP) and In-application programming (IAP)
• ROM-based USB drivers. flash updates via USB supported
• ROM-based 32-bit integer division routines
• Standard JTAG (Joint test action group) test interface for BSDL
• Serial wire debug
• Up to 8 GPIO pins can be selected as edge and level sensitive interrupt sources
• High-current source output driver (20mA) on one pin

• High-current sink driver (20mA) on true open-drain pins
• Programmable windowed watchdog timer (WWDT)
• USB 2.0 Full-speed device controller
• Crystal oscillator with an operating range of 1MHz to 25MHz
• 12MHz High-frequency Internal RC oscillator (IRC)
• Internal low-power, low-frequency watchdog oscillator (WDO)
• PLL allows CPU operation up to the maximum CPU rate
• Second, dedicated PLL is provided for USB
• Integrated PMU (power management unit)
• Four reduced power modes - Sleep, deep-sleep, power-down and deep power-down
