LPC1768UKZ Datasheet PDF - NXP

● ARM Cortex-M3 processor, running at frequencies of up to 100 MHz (LPC1768/67/66/65/64/63) or of up to 120 MHz (LPC1769). A Memory Protection Unit (MPU) supporting eight regions is included.

● ARM Cortex-M3 built-in Nested Vectored Interrupt Controller (NVIC).

● Up to 512 kB on-chip flash programming memory. Enhanced flash memory accelerator enables high-speed 120 MHz operation with zero wait states.

● In-System Programming (ISP) and In-Application Programming (IAP) via on-chip bootloader software.

● On-chip SRAM includes:

● 32/16 kB of SRAM on the CPU with local code/data bus for high-performance CPU access.

● Two/one 16 kB SRAM blocks with separate access paths for higher throughput. These SRAM blocks may be used for Ethernet, USB, and DMA memory, as well as for general purpose CPU instruction and data storage.

● Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer matrix that can be used with SSP, I2S-bus, UART, Analog-to-Digital and Digital-to-Analog converter peripherals, timer match signals, and for memory-to-memory transfers.

● Multilayer AHB matrix interconnect provides a separate bus for each AHB master. AHB masters include the CPU, General Purpose DMA controller, Ethernet MAC, and the USB interface. This interconnect provides communication with no arbitration delays.
