LPC2478

Single-chip 16-bit/32-bit micro; 512 kB flash, ethernet, CAN,

LCD, USB 2.0 device/host/OTG, external memory interface

Rev. 01 — 6 July 2007

Preliminary data sheet

1. General description

NXP Semiconductors designed the LPC2478 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

LPC2478 microcontroller has 512 kB of on-chip high-speed flash memory. This flash

memory includes a special 128-bit wide memory interface and accelerator architecture

that enables the CPU to execute sequential instructions from flash memory at the

maximum 72 MHz system clock rate. This feature is available only on the LPC2000 ARM

microcontroller family of products. The LPC2478, with real-time debug interfaces that

include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb

instructions.

The LPC2478 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 LPC2478 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 LPC2478 device

particularly suitable for industrial control and medical systems.

2. Features

ARM7TDMI-S processor, running at up to 72 MHz.

512 kB on-chip flash program memory with In-System Programming (ISP) and

In-Application Programming (IAP) capabilities. Flash program memory is on the ARM

local bus for high performance CPU access.

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 RTC power domain.
