1. General descriptionNXP Semiconductors designed the LPC2420/2460 microcontroller around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded trace. The LPC2420/2460 is flashless. The LPC2420/2460 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two instruction sets meansengineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions 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 USBfull-speed device/host/OTG controller with 4 kB of endpoint RAM, four UARTs, twoController Area Network (CAN) channels (LPC2460 only), an SPI interface, twoSynchronous Serial Ports (SSP), three I2C interfaces, and an I2S interface. Supportingthis collection of serial communication interfaces are the following feature components; anon-chip 4 MHz internal precision oscillator, 82/98 kB of total RAM consisting of 64 kB oflocal SRAM, 16 kB SRAM for Ethernet (LPC2460 only), 16 kB SRAM for general purposeDMA, 2 kB of battery powered SRAM, and an External Memory Controller (EMC). Thesefeatures make this device optimally suited for communication gateways and protocolconverters. Complementing the many serial communication controllers, versatile clockingcapabilities, 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 InterruptController (VIC), allowing the external inputs to generate edge-triggered interrupts. All ofthese features make the LPC2420/2460 particularly suitable for industrial control andmedical systems.2.
