LPC1754FBD80,518 Description
The ARM Cortex-M3 based LPC1754FBD80,518 microcontroller for embedded applications has a high level of integration and uses little power. A next-generation core, the ARM Cortex-M3 provides system improvements such improved debug tools and deeper support block integration.
Operating at CPU frequencies of up to 100 MHz is the LPC1754FBD80,518. Up to 120 MHz of CPU frequency are supported by the LPC1759. The ARM Cortex-M3 CPU uses a Harvard architecture with a three-stage pipeline, independent local instruction and data buses, and a third bus for peripherals. Additionally, the inbuilt prefetch unit of the ARM Cortex-M3 CPU allows speculative branching.
The LPC1759/58/56/54/52/51's peripheral complement consists of up to 64 kB of data memory, up to 512 kB of flash memory, Ethernet MAC, USB Device/Host/OTG interface, 8-channel general purpose DMA controller, 4 UARTs, 2 CAN channels, 2 SSP controllers, SPI interface, 2 I2C-bus interfaces, 2-input plus 2-output I2S-bus interface, 6 channel 12-bit ADC, 10-bit DAC, motor control PWM, Quadrature Encoder interface, 4 general
purpose timers, 6-output general purpose PWM, ultra-low power Real-Time Clock (RTC) with separate battery supply, and up to 52 general purpose I/O pins.
LPC1754FBD80,518 Features
- Up to 32 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 (LPC1758 only), USB, and DMA memory, as well as for general purpose CPU instruction and data storage.
ARM Cortex-M3 processor, running at frequencies of up to 100 MHz (LPC1758/56/57/54/52/51) or of up to 120 MHz (LPC1759). 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.
