45 was not very fast, lacked an RNG, and had a number of other bugs.
47 A faster and fixed version of the original, with a random number

50 A BCM5805 without public key engine or random number generator.
52 A slower version of the BCM5805.
54 Faster version of Bluesteel 5601.
56 64 bit version of the chip, and significantly more advanced.
58 Faster version of the BCM5820.

61 Faster version of the BCM5820.
63 Faster version of the BCM5822.
65 Faster version of the BCM5821, with AES hardware.
