The Brochure is a single glossy sheet. The front has a picture of a MYK-80 chip, S/N 000000414. (Do they really think they are going to need a billion serial numbers? :-) Also the following text. CAPSTONE MYK-80 A New Breakthrough in Encryption Technology Capstone offers today's most advanced encryption and authentication technology for digitized voice, data, facsimilie, EFT, EDI, and network communication available in a single IC. Capstone (known as the MYK-80) is a member of the Key Escrow Microcircuit family. Capstone features fully-selectable keys to assure system security. (Does this mean I can choose a new unit- and family-key? NOT!) MYK-80 FEATURES: -Confidentiality, integrity, and authenticity with non-repudiation. -Double Level Metal 1.0u CMOS Technology. -Four cryptographic operating modes (FIPS Pub 81). -On-board non-deterministic randomizer. -Performs NIST Digital Signature & Secure Hash Standards. -Message Encryption Key generation. -Public Key Exchange up to 1024 bits. -Key cover and uncover. -Built-in self test assures system integrity. -2^80 (or 1.2 x 10^24) possible selectable keys. -Exportable in products meeting the NIST FIPS Pub 140.1 and government approval. On the back: MYK-80 Designed by Mykotronx, Inc., manufactured by VLSI Technology, INC., and programmed by Mykotronx, Inc., the MYK-80 features a complete 32-bit RISC-based cryptographic processor. A Type 2 government encryption/decryption algorithm - called "Skipjack" - is implemented with an 80-bit cryptovariable key. The MYK-80 also implements NIST Digital Signature and Secure Hash Standards. Block Diagram: Picture of a central circle, labeled Memory Management Unit, surrounded by eight triangles, labeled Secure Logic, vROM 512x32, Expo 1024, RISC ARM 6, Skipjack, RAM 256x32, Randomizer. Specifications: - Cyrptographic modes: 64-bit ECB, 64-bit CBC, 8/16/32/64-bit CFB, and 64-bit OFB. -Two package configurations: 176-pin TQFP (shown) & 180-pin CPGA (1.575" x 1.575" x 0.25") -Processing rate: ECB at 12 Mbps and CBC at 10 Mbps. -RISC processor: 32-bit ARM 6 running at 18 MIPS. -Max system clock rate: 20MHz - Power dissipation: 20mW/MHz at 5VDC (approx.) - Operational temperature range: 0deg to 85deg. (Note: there is no indication of scale, so I would assume it's Celsisus) - Operating voltage: Vdd = 5 V +/- 10% - 32-bit data and address busses. - TTL I/O compatible and low power. Pin Configuration: [Diagram deleted. Just a standard outline of a 176-pin TQFP. No indication of which pins are which, etc.] [And down at the bottom:] Mykotronx Inc. 357 Van Ness Way, Suite 200, Torrance CA 90501 Tel: (310) 533-8100 * FAX: (310) 533-0527 Application notes, pricing, availability, and other additional information may be obtained by contacting the marketing manager at Mykotronx. The MYK-80 is freely exportable in products meeting NIST FIPS Pub 140.1 and government approval. Printed in U.S.A. - Oct 93 ----------------------- And that's all the info I have for now.
