1.General descriptionThe LPC2387 microcontroller is based on a 16-bit/32-bit ARM7TDMI-S CPU withreal-time emulation that combines the microcontroller with 512 kB of embeddedhigh-speed flash memory. A 128-bit wide memory interface and a unique acceleratorarchitecture enable 32-bit code execution at the maximum clock rate. For criticalperformance in interrupt service routines and DSP algorithms, this increases performanceup to 30 % over Thumb mode. For critical code size applications, the alternative 16-bitThumb mode reduces code by more than 30 % with minimal performance penalty.The LPC2387 is ideal for multi-purpose serial communication applications. It incorporatesa 10/100 Ethernet Media Access Controller (MAC), USB full speed device with 4 kB ofendpoint RAM, four UARTs, two CAN channels, an SPI interface, two Synchronous SerialPorts (SSP), three I2C interfaces, and an I2S interface. This blend of serialcommunications interfaces combined with an on-chip 4 MHz internal oscillator, 64 kBSRAM, 16 kB SRAM for Ethernet, 16 kB SRAM for USB and general purpose use,together with 2 kB battery powered SRAM makes this device very well suited forcommunication gateways and protocol converters. Various 32-bit timers, an improved10-bit ADC, 10-bit DAC, one PWM unit, a CAN control unit, and up to 70 fast GPIO lineswith up to 12 edge or level sensitive external interrupt pins make this microcontrollerparticularly suitable for industrial control and medical systems.2.Features and benefits ARM7TDMI-S processor, running at up to 72 MHz. 512 kB on-chip flash program memory with In-System Programming (ISP) andIn-Application Programming (IAP) capabilities. Flash program memory is on the ARMlocal bus for high performance CPU access. 64 kB of SRAM on the ARM local bus for high performance CPU access. 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM. 16 kB SRAM for general purpose DMA use; also accessible by the USB. Dual Advanced High-performance Bus (AHB) system that provides for simultaneousEthernet DMA, USB DMA, and program execution from on-chip flash with nocontention between those functions. A bus bridge allows the Ethernet DMA to accessthe other AHB subsystem. Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts. General Purpose DMA (GPDMA) on AHB controller that can be used with the SSPserial interfaces, the I2S port, and the Secure Digital/MultiMediaCard (SD/MMC) cardport, as well as for memory-to-memory transfers.LPC2387Single-chip 16-bit/32-bit MCU; 512 kB flash with ISP/IAP,Ethernet, USB 2.0 device/host/OTG, CAN, and 10-bit ADC/DACRev. 5.1 — 16 October 2013Product data sheet
