LPC2103：
ARM7TDMI-S based high-performance 32-bit RISC Microcontroller with Thumb extensions
10-bit A/D converters provides eight analog inputs,
Two 32-bit timers/external event counters,
Two 16-bit timers/external event counters,
Low power Real-Time Clock (RTC) with dedicated 32 kHz clock input,
Multiple serial interfaces including two UARTs (16C550),
two Fast I2C-buses (400 kbit/s), SPI and SSP with buffering and variable data length capabilities
32KB on-chip Flash ROM with In-System Programming (ISP) and In-Application Programming (IAP), 8KB RAM
LPC2131：
ARM7TDMI-S based high-performance 32-bit RISC Microcontroller with Thumb extensions
32 KB on-chip Flash ROM with In-System Programming (ISP) and In-
Application Programming (IAP), Two 8-ch 10bit ADC
8 KB RAM, Vectored Interrupt Controller,
Two UARTs, one with full modem interface.
Two I2C serial interfaces, Two SPI serial interfaces
Three 32-bit timers, Real Time Clock, Watchdog Timer,
General purpose I/O pins.
CPU clock up to 60 MHz, On-chip crystal oscillator and On-chip PLL
我觉得入门的话，跟着周立功的教程是比较好的学习方法。他的配套教材丰富，规范。
但是，从我的出发点，我想说，学习ARM嵌入式系统，最终是要结合嵌入式操作系统，完成整个系统的设计，现在主流的操作系统2.6内核的Linux在ARM7系列芯片上是跑不了的。
我在开发的时候就受这方面的制约。只能跑2.4内核的uCLinux，技术进步性远远落后。
所以建议你从ARM9内核入门，将来学以致用。
