Sunnyvale, Calif.Maxim Integrated Products has introduced the DS28CN01, a secure memory device that provides bidirectional challenge-and-response authentication protection by using the internationally recognized SHA-1 (Secure Hash Algorithm) cryptographic algorithm.
A 1kb EEPROM array and associated command set ensure tamper-proof storage of data written to the integrated nonvolatile data array. Each EEPROM page is protected against data modification by the SHA-1 algorithm, and also includes programmable write protection and EPROM/OTP (one-time-programmable) emulation modes.
The DS28CN01 is well-suited for a broad range of cost-sensitive end equipment in which intellectual property needs to be protected and/or equipment features need to be securely controlled, such as network routers/switches, notebook PC battery packs, laser and inkjet printer cartridges, and GPS navigators.
Pricing: Starts at $0.65 (1000-up, FOB USA).
Availability: Now in an 8-pin microSOP.
