LPC1342FHN33,551

The LPC1342FHN33,551 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 16kB internal flash, 4kB 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)
• In-system programming (ISP) and In-application programming (IAP)
• Selectable boot-up - UART or USB
• USB MSC and HID on-chip drivers
• USB 2.0 Full-speed device controller with on-chip PHY for device
• UART with fractional baud rate generation, modem, internal FIFO and RS-485/EIA-485 support
• SSP controller with FIFO and multi-protocol capabilities
• Four general purpose counter/timers
• Programmable watchdog timer (WDT)
• System tick timer
• Serial wire debug and serial wire trace port
• High-current output driver (20mA) on one pin
• High-current sink drivers (20mA) on two I2C-bus pins in fast-mode Plus
• Integrated PMU (power management unit)
• Three reduced power modes - sleep, deep-sleep and deep power-down
• GPIO pins can be used as edge and level sensitive interrupt sources
• Clock output function with divide
• Processor wake-up from deep-sleep mode
• Brownout detect with four separate thresholds
• Power-on reset (POR)
• Integrated oscillator with an operating range of 1MHz to 25MHz
• 12MHz Internal RC oscillator trimmed to 1 % accuracy
• Programmable watchdog oscillator with a frequency range of 7.8kHz to 1.8MHz
• System PLL allows CPU operation up to the maximum CPU rate
• Code read protection (CRP) with different security levels
