LPC1756FBD80Y
Overview
The LPC1756FBD80Y is a high-performance 32-bit microcontroller based on the ARM Cortex-M3 core, operating at frequencies up to 100MHz. It features 256KB of Flash memory and 32KB of SRAM, providing a balanced memory-to-performance ratio for mainstream embedded applications. The device includes a nested vectored interrupt controller (NVIC) and an internal memory protection unit (MPU) for robust software execution.
Why Choose This Part
The LPC1756 offers a high integration level with its internal PLL and oscillator, reducing the external component count. Its sophisticated power management includes four low-power modes, such as Deep power-down, which consumes as little as 31uA. Additionally, features like In-System Programming (ISP) and In-Application Programming (IAP) simplify firmware updates in the field.
Applications
Getting Started
Development can be performed using NXP MCUXpresso IDE or third-party tools like Keil MDK or IAR Embedded Workbench. Engineers should leverage the available CMSIS-compliant drivers for the Cortex-M3 core and use an SWD/JTAG debugger such as a SEGGER J-Link for firmware deployment. Initial prototyping is often done using the LPCXpresso1769 development board, which shares architectural similarities with this 80-pin LQFP variant.
