NXP | LPC1769FBD100,551

The LPC1769 are 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 LPC1769 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. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching.

Features:

• ARM Cortex-M3 processor, running at frequencies of up to 100 MHz. A 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. Enhanced flash memory accelerator enables high-speed 100 MHz operation with zero wait states
• In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software
• On-chip SRAM includes
• Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer matrix that can be used with SSP, I2S-bus, UART, Analog-to-Digital and Digital-to-Analog converter peripherals, timer match signals, and for memory-to-memory transfers
• Multilayer AHB matrix interconnect provides a separate bus for each AHB master. AHB masters include the CPU, General Purpose DMA controller, Ethernet MAC, and the USB interface. This interconnect provides communication with no arbitration delays
• Split APB bus allows high throughput with few stalls between the CPU and DMA
• Serial interfaces
• Standard JTAG test/debug interface for compatibility with existing tools. Serial Wire Debug and Serial Wire Trace Port options
• Available as 100-pin LQFP package (14 × 14 × 1.4 mm)

Applications:

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