The LPC1766 are ARM Cortex-M3 based microcontrollers for embedded applications featuring a high level of integration and low power consumption. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The LPC1766 operate at CPU frequencies of up to 100 MHz. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching. The LPC1766 is pin-compatible to the 100-pin LPC236x ARM7-based microcontroller series.
- ARM Cortex-M3 processor, running at frequencies of up to 100 MHz LPC1766. 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.
- Serial interfaces: Ethernet MAC, USB 2.0
- Single 3.3 V power supply (2.4 V to 3.6 V)
- Crystal oscillator with an operating range of 1 MHz to 25 MHz
- Available as LQFP100 (14 mm x 14 mm x 1.4 mm), TFBGA1001 (9 mm x 9 mm x 0.7 mm).
