LPC1769 Datasheet - NXP Semiconductors.

Features and benefits
* ARM Cortex-M3 processor, running at frequencies of up to 100 MHz
(LPC1768/67/66/65/64/63) or ofup 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.
