●The LPC1346FHN33 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 26 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
