Preliminary data sheet
1. 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.
The LPC2470 microcontroller incorporates an LCD controller, a 10/100 Ethernet Media
Access Controller (MAC), a USB full-speed Device/Host/OTG Controller with 4 kB of
endpoint RAM, four UARTs, two Controller Area Network (CAN) channels, an SPI
interface, two Synchronous Serial Ports (SSP), three I²C interfaces, and an I²S interface.
Supporting this collection of serial communications interfaces are the following feature
components; an on-chip 4 MHz internal oscillator, 98 kB of total RAM consisting of 64 kB
of local SRAM, 16 kB SRAM for Ethernet, 16 kB SRAM for general purpose DMA, 2 kB of
battery powered SRAM, and an External Memory Controller (EMC). These features make
this device optimally suited for portable electronics and Point-of-Sale (POS) applications.
Complementing the many serial communication controllers, versatile clocking capabilities,
and memory features are various 32-bit timers, a 10-bit ADC, 10-bit DAC, two PWM units,
and up to 160 fast GPIO lines. The LPC2470 connects 64 of the GPIO pins to the
hardware based Vector Interrupt Controller (VIC) that means these external inputs can
generate edge-triggered interrupts. All of these features make the LPC2470 device
particularly suitable for industrial control and medical systems.
