LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
 Hardware floating-point unit (not all versions).
 Non-maskable Interrupt (NMI) input.
 JTAG and Serial Wire Debug (SWD), serial trace, eight breakpoints, and four watch
points.
 System tick timer.
 System:
 Multilayer AHB matrix interconnect provides a separate bus for each AHB master.
AHB masters include the CPU, and General Purpose DMA controller. This
interconnect provides communication with no arbitration delays unless two masters
attempt to access the same slave at the same time.
 Split APB bus allows for higher throughput with fewer stalls between the CPU and
DMA. A single level of write buffering allows the CPU to continue without waiting for
completion of APB writes if the APB was not already busy.
 Embedded Trace Macrocell (ETM) module supports real-time trace.
 Boundary scan for simplified board testing.
 Memory:
 512 kB on-chip flash program memory with In-System Programming (ISP) and
In-Application Programming (IAP) capabilities. The combination of an enhanced
flash memory accelerator and location of the flash memory on the CPU local
code/data bus provides high code performance from flash.
 Up to 96 kB on-chip SRAM includes:
64 kB of main SRAM on the CPU with local code/data bus for high-performance
CPU access.
Two 16 kB peripheral SRAM blocks with separate access paths for higher
throughput. These SRAM blocks may be used for DMA memory as well as for
general purpose instruction and data storage.
 Up to 4032 byte on-chip EEPROM.
 LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film
Transistors (TFT) displays.
 Dedicated DMA controller.
 Selectable display resolution (up to 1024  768 pixels).
 Supports up to 24-bit true-color mode.
 External Memory Controller (EMC) provides support for asynchronous static memory
devices such as RAM, ROM and flash, as well as dynamic memories such as single
data rate SDRAM.
 Eight channel General Purpose DMA controller (GPDMA) on the AHB multilayer
matrix that can be used with the SSP, I2S, UART, CRC engine, Analog-to-Digital and
Digital-to-Analog converter peripherals, timer match signals, GPIO, and for
memory-to-memory transfers.
 Serial interfaces:
 Quad SPI Flash Interface (SPIFI) with four lanes and up to 40 MB per second.
 Ethernet MAC with MII/RMII interface and associated DMA controller. These
functions reside on an independent AHB.
 USB 2.0 full-speed dual port device/host/OTG controller with on-chip PHY and
associated DMA controller.
