1. 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 I
2
C interfaces, and an I
2
S interface. Supporting
this collection of serial communications 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) that means these external inputs can generate
edge-triggered interrupts. All of these features make the LPC2420/2460 particularly
suitable for industrial control and medical systems.
2. 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).
