The LPC2000 family can be further divided into 5 groups: LPC21xx and LPC22xx.

LPC21xx

The LPC21xx come in a tiny 7mmx7mm LQFP48 package. Some of them cost less than a typical 8-bit microcontroller -- less than $5 in ones from Digikey 2008. LPC21xx

LPC22xx

The LPC22xx series are much like the LPC21xx series, but with external busses. LPC22xx

LPC23xx

Most LPC23xx come in a LQFP-100 package. Some of them cost more than the higher-end 8-bit microcontroller -- less than $9 in ones from Digikey 2008. Those have no external data bus, but they can simultaneously run the application, USB 2.0 "full-speed", CAN 2.0B with two channels, and Ethernet 10/100. Also 10 bit ADC (6 inputs) and a 10 bit DAC. Also I2S, three I2C, three SPI/SSP, and four UARTs.

LPC24xx

The LPC24xx series come in a LQFP-208 or TFBGA-208 package.

LPC29xx
