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-triggeredBinterrupts. All of these features make the LPC2420/2460 particularly suitable for industrial control and medical systems
