General description
NXP Semiconductors designed the LPC2470 microcontroller, powered by the ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of applications that require advanced communications and high quality graphic displays. The LPC2470 microcontroller is flashless. The LPC2470, with real-time debug interfaces that include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb instructions.
FEATUREs and benefits
◾ ARM7TDMI-S processor, running at up to 72 MHz.
◾ 98 kB on-chip SRAM includes:
✦ 64 kB of SRAM on the ARM local bus for high performance CPU access.
✦ 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
✦ 16 kB SRAM for general purpose DMA use also accessible by the USB.
✦ 2 kB SRAM data storage powered from the Real-Time Clock (RTC) power domain.
◾ 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.
◾ Dual Advanced High-performance Bus (AHB) system allows simultaneous Ethernet
DMA, and USB DMA with no contention.
◾ 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.
◾ Advanced Vectored Interrupt Controller (VIC), supporting up to 32 vectored interrupts.
◾ General Purpose DMA controller (GPDMA) on AHB that can be used with the SSP,
I2S-bus, and Secure Digital/MultiMediaCard (SD/MMC) interface as well as for
memory-to-memory transfers.
◾ Serial Interfaces:
✦ 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.
✦ Four UARTs with fractional baud rate generation, one with modem control I/O, one
with IrDA support, all with FIFO.
✦ CAN controller with two channels.
✦ SPI controller.
✦ Two SSP controllers, with FIFO and multi-protocol capabilities. One is an alternate
for the SPI port, sharing its interrupt. SSPs can be used with the GPDMA controller.
✦ Three I2C-bus interfaces (one with open-drain and two with standard port pins).
✦ I2S (Inter-IC Sound) interface for digital audio input or output. It can be used with
the GPDMA.
