Discovery The device provides a core set of cryptographic tools de- Efficient Secure Hash Algorithm to Authenticate rived from integrated blocks including a SHA-3 engine, Peripherals 256 bits of secured user EEPROM, a decrement-only FIPS 202-Compliant SHA-3 Algorithm for counter, and a unique 64-bit ROM identification number Challenge/Response Authentication (ROM ID). The unique ROM ID is used as a fundamental FIPS 198-Compliant Keyed-Hash Message input parameter for cryptographic operations and serves Authentication Code (HMAC) as an electronic serial number within the application. Supplemental Features Enable Easy Integration into End Applications Applications 17-Bit, One-Time Settable, Nonvolatile Decrement- Medical Tools/Accessories Authentication and Only Counter with Authenticated Read Calibration Secure Storage for Secrets Accessory and Peripheral Secure Authentication 256 Bits of Secure EEPROM for User Data Battery Authentication and Charge Cycle Tracking Unique and Unalterable Factory Programmed 64-Bit Identification Number (ROM ID) 2 I C Communications up to 1MHz Operating Range: 1.62V to 3.63V, -40C to +85C Request DS28C16 8-Pin, 2mm x 2mm TDFN-EP Package Security User Guide Ordering Information appears at end of data sheet.

Package Information 8 TDFN-EP Package Code T822+3C Outline Number 21-0168 Land Pattern Number 90-0065 Thermal Resistance, Single-Layer Board: Junction to Ambient ( ) JA Junction to Case ( ) JC Thermal Resistance, Four-Layer Board: Junction to Ambient ( ) 85.1C/W JA Junction to Case ( ) 20.8C/W JC For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial. Electrical Characteristics (Limits are 100% tested at T = +25C and T = +85C. Limits over the operating temperature range and relevant supply voltage A A range are guaranteed by design and characterization. Specifications marked GBD are guaranteed by design and not production tested. Specifications to the minimum operating temperature are guaranteed by design and are not production tested.)
