Communication-rich MCU integrates ARM7 core and large memories

The LPC2387 ARM7-based MCU from NXP Semiconductors combines 32-bit processing, 512kbyte on-chip Flash, large on-chip SRAMs and a 4MHz internal oscillator with popular serial-communication peripherals.

Ideal for multi-purpose serial-communication applications, the LPC2387 features a 10/100 Ethernet Media Access Controller (MAC), USB Full-Speed device with 4kbyte of endpoint RAM, four UARTs, two CAN channels, an SPI interface, two Synchronous Serial Ports (SSP), three I²C interfaces, and an I²S interface. The large 64kbyte SRAM, plus 16kbyte SRAM for Ethernet, 16kbyte SRAM for USB and general-purpose use, and 2kbyte battery-backed SRAM help designers take maximum advantage of the MCU’s extensive communication interfaces. A Secure Digital/Multimedia Card (SD/MMC) port is also provided.

The processing engine uses the ARM7TDMI-S CPU, and features 128-bit memory-interface width and a unique accelerator architecture that enables 32-bit code execution at the maximum clock rate. This increases performance by up to 30% while also leaving developers free to use the 16-bit Thumb instruction set where code size is critical.
