RNG90-SSVDA-T

The RNG90-SSVDA-T delivers the Microchip RNG90 hardware random number generator in an 8-lead SOIC, the gull-wing package that is easy to place, inspect, and hand-rework. It belongs to the CryptoAuthentication family and combines a physical non-deterministic noise source with a SHA-256 Hash_DRBG, emitting a 256-bit random value with 128-bit security strength each time the Random command runs. A Fast-Mode I2C interface, a 1.65V to 5.5V supply, and a -40°C to 105°C range round out a straightforward entropy source.

Key Features

• Physical noise source - a hardware entropy source seeds a NIST-style deterministic generator, so randomness does not depend on software.
• 256-bit output - each Random command returns a 256-bit number carrying 128 bits of security strength.
• NIST SP 800-90A/B/C design - the Hash_DRBG is certified under the NIST CAVP program, with the entropy source built toward SP 800-90B validation.
• FIPS 140-3 readiness - integrated health tests and self-tests target CMVP Entropy Source Validation for certified end products.
• Simple I2C link - Fast-Mode I2C up to 400 kHz connects the device to virtually any host.
• Tamper defenses - active shield, glitch protection, and voltage and temperature tamper detection protect operation.
• Very low sleep current - roughly 130 nA in sleep keeps the part practical for battery-powered and always-on designs.
• Power-up self-test - firmware integrity and entropy health tests run at power-up and wake, reporting a defined status on failure.

Typical Applications

• Industrial and networking boards - the robust SOIC footprint suits equipment where manufacturability and inspection matter.
• Cryptographic key generation - seeding keys, nonces, and challenges for secure communications.
• Certified-product designs - systems seeking FIPS entropy-source validation.

Unique Advantages

• Easy-to-handle package - the 8-lead SOIC is the practical choice when assembly and rework favor a larger, visually inspectable footprint over the UDFN.
• Hardware-rooted randomness - a certified Hash_DRBG fed by a physical noise source avoids the pitfalls of pseudo-random software.
• Broad operating window - a 1.65V to 5.5V supply and operation to 105°C make it flexible across many designs.
• Library-supported - Microchip's CryptoAuthentication software eases host-side integration over the I2C link.
