NXP LPC2387FBD100,551: A Comprehensive Technical Overview of the ARM7-Based Microcontroller
The NXP LPC2387FBD100,551 stands as a prominent member of the LPC2300 family, representing a highly integrated microcontroller designed for complex embedded applications that demand robust performance, extensive connectivity, and low power consumption. Built around the ARM7TDMI-S core, this microcontroller operates at CPU frequencies of up to 72 MHz, providing a powerful yet efficient processing backbone for a wide range of industrial, automotive, and consumer systems.
A defining characteristic of the LPC2387 is its exceptional integration. It consolidates a vast array of peripherals into a single 100-pin LQFP package, significantly reducing system component count and overall board space. Its rich set of on-chip peripherals includes a 10/100 Ethernet MAC, a full-speed USB 2.0 Device/Controller with 4 kB of endpoint RAM, four UARTs, two CAN 2.0B controllers, an SPI interface, three I²C-bus interfaces, and an I²S interface. This makes it an ideal solution for networked and connected devices, gateway products, and multi-protocol communication hubs.
The microcontroller is further equipped with 512 kB of high-speed on-chip Flash memory and 98 kB of on-chip SRAM, including 64 kB of SRAM specifically designed to support Ethernet and USB operations. This substantial memory architecture, accessible via two ARM Advanced High-performance Bus (AHB) system buses, allows for zero-wait-state execution and efficient data handling for high-bandwidth peripherals.
For precision control and system interfacing, the LPC2387 incorporates a 10-bit ADC with up to 8 channels, a 10-bit DAC, two PWM blocks, and up to 70 general-purpose I/O pins. Its advanced vectored interrupt controller (VIC) ensures low-latency interrupt handling, which is critical for real-time control applications. Furthermore, features like an on-chip real-time clock (RTC), watchdog timer, and brown-out detect enhance the reliability of the system.
Operating from a single 3.3V power supply, the device also includes advanced power-saving modes, including Idle and Power-down, which are essential for battery-powered or energy-sensitive applications. The combination of processing power, comprehensive connectivity, and integrated memory solidifies the LPC2387FBD100,551's position as a versatile and capable solution for demanding embedded designs.
