LPC2420 Overview
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.
LPC2420 Key Features
- 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
- 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 (LPC246
- EMC provides support for asynchronous static memory devices such as RAM, ROM and flash, as well as dynamic
