DALPU-4 NEOWINE Crypto and Authentication DATASHEET
◼The following sections introduce the features and functions of the DALPU-4 crypto device.
●Device Features
◼The DALPU-4has an Electrically Erasable Programmable Read-Only Memory (EEPROM). The EEPROM can be used for key storage, miscellaneous write/read data, read-only, secret data, consumption logging, and security configuration. DALPU-4has 32-bit ARM Cortex-M3Core. This core is in charge of public key operation. DALPU-4has 32Kbytes SRAM, it is used for M3code execution region and user code region. DALPU-4has SPI0, SPI1, UART and GPIO interfaces. SPI0 can have a slave mode. With SPI0 user can control symmetric cipher core. SPI1 can have both a slave and a master mode. With SPI1 in a slave mode, user can control asymmetric cipher core. DALPU-4has a power saving mode. In sleep mode internal oscillator is disabled. DALPU-4has a symmetric cipher function which is ECC-P256, ECDSA and ECDH. DALPU-4has a symmetric cipher function which is AES-128/256. AES supports ECB, CBC, CFB, OFB, CTR operating modes.
●Benefits
◼Read/Write, Encrypted, or Read-only User Zone Options
◼Ease use of Crypto Device to replace of existing EEPROM devices
◼Authenticate Consumer products, Components, and Network equipment
◼Protect Sensitive Firmware
◼Securely Store Sensitive Data
◼Manage Warranty Claims
◼Securely Store Identity Data
