LPC1765FET100,551

The LPC1765FET100,551 is a 32-bit Microcontroller based on ARM Cortex-M3 core with RISC architecture operates at a maximum frequency of 100MHz. 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 256kB internal flash, 64kB internal RAM, USB Device/Host/OTG interface, 8-channel general purpose DMA controller, 8-channel 12-bit A/D converter, 10-bit D/A converter, motor control PWM, quadrature encoder interface, four general purpose timers, 6-output general purpose PWM, ultra-low power real-time clock (RTC) with separate battery supply and 70 general-purpose I/O pins.

• ARM Cortex-M3 built-in nested vectored interrupt controller (NVIC)
• In-system programming (ISP) and In-application programming (IAP)
• Multilayer AHB matrix interconnect
• Split APB bus
• Standard JTAG debug interface for compatibility
• Emulation trace module enables non-intrusive, high-speed real-time tracing of instruction execution
• Integrated PMU (power management unit)
• Four reduced power modes - Sleep, deep-sleep, power-down and deep power-down
• Four external interrupt inputs configurable as edge/level sensitive
• Non-maskable Interrupt (NMI) input
• The wake-up interrupt controller (WIC)
• Brownout detect with separate threshold for interrupt and forced reset
• Power-on reset (POR)
• Crystal oscillator with an operating range of 1MHz to 25MHz
• 4MHz Internal RC oscillator trimmed to 1 % accuracy
• PLL allows CPU operation up to the maximum CPU rate
• USB PLL for added flexibility
• Code read protection (CRP) with different security levels
• Unique device serial number for identification purposes
