Spoločnosť NXP predstavila najmenší ARM procesor - LPC1102 zaberajúci iba niečo cez 2x2mm.
LPC1102 je ARM Cortex-M0 procesor, pracujúci do 50MHz, poskytujúci 45 DMIPS výkon.
Obsahuje 32kB FLASH a 8 kB RAM pamäte, jeden RS-485/EIA-485 UART, SPI s SPP, 4 čítače/časovače 10-bitový AD prevodník a 11 I/O pinov.
Kremík je oblečený do 16 pinového WLCSP púzdra (ball- grid).
