The LPC1346FBD48 is a 32-bit Microcontroller based on ARM Cortex-M3 core with RISC architecture operates at a maximum frequency of 72MHz. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching. The device incorporates 48kB internal flash, 8kB internal RAM, 8-channel 10-bit A/D converter and 40 general-purpose I/O pins.

• ARM Cortex-M3 built-in nested vectored interrupt controller (NVIC)
• Non maskable interrupt (NMI) input selectable from several input sources
• System tick timer
• Standard JTAG test interface for BSDL
• Serial wire debug
• Support for ETM ARM Cortex-M3 debug time stamping
• 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
• Four general purpose counter/timers
• Programmable windowed watchdog timer (WWDT)
• Repetitive interrupt timer (RI Timer)
• USB 2.0 Full-speed device controller with on-chip ROM-based USB driver library
• Two SSP controllers with FIFO and multi-protocol capabilities
• Crystal oscillator with an operating range of 1MHz to 25MHz
• 12MHz High-frequency internal RC oscillator (IRC) trimmed to 1 % accuracy
• 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
• Four reduced power modes - Sleep, deep-sleep, power-down and deep power-down
