1. general description the lpc2387 microcontroller is based on a 16-bit/32-bit arm7tdmi-s cpu with real-time emulation that combines the microcontroller with 512 kb of embedded high-speed ?ash memory. a 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. for critical performance in interrupt service routines and dsp algorithms, this increases performance up to 30 % over thumb mode. for critical code size applications, the alternative 16-bit thumb mode reduces code by more than 30 % with minimal performance penalty. the lpc2387 is ideal for multi-purpose serial communication applications. it incorporates a 10/100 ethernet media access controller (mac), usb full speed device with 4 kb of endpoint ram, four uarts, two can channels, an spi interface, two synchronous serial ports (ssp), three i 2 c interfaces, and an i 2 s interface. this blend of serial communications interfaces combined with an on-chip 4 mhz internal oscillator, 64 kb sram, 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 for communication gateways and protocol converters. various 32-bit timers, an improved 10-bit adc, 10-bit dac, one pwm unit, a can control unit, and up to 70 fast gpio lines with up to 12 edge or level sensitive external interrupt pins make this microcontroller particularly suitable for industrial control and medical systems. 2. features n arm7tdmi-s processor, running at up to 72 mhz. n 512 kb on-chip ?ash program memory with in-system programming (isp) and in-application programming (iap) capabilities. flash program memory is on the arm local bus for high performance cpu access. n 64 kb of sram on the arm local bus for high performance cpu access. n 16 kb sram for ethernet interface. can also be used as general purpose sram. n 16 kb sram for general purpose dma use also accessible by usb. n dual advanced high-performance bus (ahb) system that provides for simultaneous ethernet dma, usb dma, and program execution from on-chip ?ash with no contention between those functions. a bus bridge allows the ethernet dma to access the other ahb subsystem. n advanced vectored interrupt controller (vic), supporting up to 32 vectored interrupts. n general purpose dma (gpdma) on ahb controller that can be used with the ssp serial interfaces, the i 2 s port, and the secure digital/multimediacard (sd/mmc) card port, as well as for memory-to-memory transfers. lpc2387 single-chip 16-bit/32-bit mcu; 512 kb ?ash with isp/iap, ethernet, usb 2.0 device/host/otg, can, and 10-bit adc/dac rev. 03 29 october 2008 product data sheet

C stop timer on match with optional interrupt generation. C reset timer on match with optional interrupt generation. ? supports single edge controlled and/or double edge controlled pwm outputs. single edge controlled pwm outputs all go high at the beginning of each cycle unless the output is a constant low. double edge controlled pwm outputs can have either edge occur at any position within a cycle. this allows for both positive going and negative going pulses. ? pulse period and width can be any number of timer counts. this allows complete ?exibility in the trade-off between resolution and repetition rate. all pwm outputs will occur at the same repetition rate.
