LPC2420 Product details

General description
NXP Semiconductors designed the LPC2420/2460 microcontroller around a 16-bit/32-bit
ARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG and
embedded trace. The LPC2420/2460 is flashless. The LPC2420/2460 can execute both
32-bit ARM and 16-bit Thumb instructions. Support for the two instruction sets means
engineers can choose to optimize their application for either performance or code size at
the sub-routine level. When the core executes instructions in Thumb state it can reduce
code size by more than 30 % with only a small loss in performance while executing
instructions in ARM state maximizes core performance.
The LPC2420/2460 microcontroller is ideal for multi-purpose communication applications.
It incorporates a 10/100 Ethernet Media Access Controller (MAC) (LPC2460 only), a USB
full-speed device/host/OTG controller with 4 kB of endpoint RAM, four UARTs, two
Controller Area Network (CAN) channels (LPC2460 only), an SPI interface, two
Synchronous Serial Ports (SSP), three I2C interfaces, and an I2S interface. Supporting
this collection of serial communication interfaces are the following feature components; an
on-chip 4 MHz internal precision oscillator, 82/98 kB of total RAM consisting of 64 kB of
local SRAM, 16 kB SRAM for Ethernet (LPC2460 only), 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 communication gateways and protocol
converters. Complementing the many serial communication controllers, versatile clocking
capabilities, and memory features are various 32-bit timers, an improved 10-bit ADC,
10-bit DAC, two PWM units, four external interrupt pins, and up to 160 fast GPIO lines.
The LPC2420/2460 connects 64 of the GPIO pins to the hardware based Vector Interrupt
Controller (VIC), allowing the external inputs to generate edge-triggered interrupts. All of
these features make the LPC2420/2460 particularly suitable for industrial control and
medical systems.

Features and benefits
 ARM7TDMI-S processor, running at up to 72 MHz.
 82/98 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.
(LPC2460 only)
 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.
 Dual Advanced High-performance Bus (AHB) system allows simultaneous Ethernet
DMA, and USB DMA with no contention (LPC2460 only).
 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, and SD/MMC interface as well as for memory-to-memory transfers.
 Serial Interfaces:
 Ethernet MAC with MII/RMII interface and associated DMA controller (LPC2460
only). 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 (LPC2460 only).
 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.
 Other peripherals:
 SD/MMC memory card interface.
 160 General purpose I/O pins with configurable pull-up/down resistors.
 10-bit ADC with input multiplexing among 8 pins.
 10-bit DAC.
 Four general purpose timers/counters with 8 capture inputs and 10 compare
outputs. Each timer block has an external count input.
 Two PWM/timer blocks with support for three-phase motor control. Each PWM has
an external count inputs.
 RTC with separate power domain. Clock source can be the RTC oscillator or the
APB clock.
 2 kB SRAM powered from the RTC power pin, allowing data to be stored when the
rest of the chip is powered off.
 WatchDog Timer (WDT). The WDT can be clocked from the internal RC oscillator,
the RTC oscillator, or the APB clock.
 Standard ARM test/debug interface for compatibility with existing tools.
 Emulation trace module supports real-time trace.
 Single 3.3 V power supply (3.0 V to 3.6 V).
 Four reduced power modes: idle, sleep, power-down, and deep power-down.
 Four external interrupt inputs configurable as edge/level sensitive. All pins on port 0
and port 2 can be used as edge sensitive interrupt sources.
 Processor wake-up from Power-down mode via any interrupt able to operate during
Power-down mode (includes external interrupts, RTC interrupt, USB activity, port 0/2
pin interrupt, Ethernet wake-up interrupt (LPC2460 only), CAN bus activity (LPC2460
only)).
 Two independent power domains allow fine tuning of power consumption based on
needed features.
 Each peripheral has its own clock divider for further power saving. These dividers help
reduce active power by 20 % to 30 %.
 Brownout detect with separate thresholds for interrupt and forced reset.
 On-chip power-on reset.
 On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.
 4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as
the system clock. When used as the CPU clock, does not allow CAN and USB to run.
 On-chip PLL allows CPU operation up to the maximum CPU rate without the need for
a high frequency crystal. May be run from the main oscillator, the internal RC oscillator,
or the RTC oscillator.
 Boundary scan for simplified board testing.
 Versatile pin function selections allow more possibilities for using on-chip peripheral
functions.
