NXP | LPC1756FBD80,551

LPC1756FBD80,551 is a ARM Cortex-M3 based microcontrollers for embedded applications featuring a high level of integration and low power consumption. 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 LPC1758/56/57/54/52/51 operate at CPU frequencies of up to 100 MHz. The LPC1759 operates at CPU frequencies of up to 120 MHz. 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.

Features:

• ARM Cortex-M3 processor:
  • Freq up to 100 MHz (LPC1758/56/57/54/52/51) 
  • 120 MHz (LPC1759).
  • Memory Protection Unit (MPU) supporting eight regions is included.
• ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).
• Up to 512 kB on-chip flash programming memory.
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.
• On-chip SRAM includes:
  • Up to 32 kB of SRAM on the CPU with local code/data bus for high-performance CPU access.
  • Two/one 16 kB SRAM blocks with separate access paths for higher throughput.
• Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer matrix
• Split APB bus allows high throughput with few stalls between the CPU and DMA.

Applications :

• eMetering
• Lighting
• Industrial networking
• Alarm systems
• White goods
