ARM9 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use.[1] The ARM9 core family consists of ARM9TDMI, ARM940T, ARM9E-S, ARM966E-S, ARM920T, ARM922T, ARM946E-S, ARM9EJ-S, ARM926EJ-S, ARM968E-S, ARM996HS. ARM9 cores were released from 1998 to 2006 and they are no longer recommended for new IC designs; recommended alternatives include ARM Cortex-A, ARM Cortex-M, and ARM Cortex-R cores.[citation needed]
