DS1963S is a financial iButton with SHA-1 functionality and a 4k-bit read/write data area. It has a 4096-bit non-volatile (NV) memory, divided into 16 pages of 256 bits each. It also features independent 64-bit keys and 32-bit read-only, non-rolling page write counters. The device also includes a 512-bit SHA-1 engine that can calculate a 160-bit message authentication code (MAC) and can be used as a co-processor for roaming iButtons or hosts.
The DS1963S is a financial iButton featuring SHA-1 functionality and multiple read/write data areas. It allows for the creation of public and private data micro-databases within its non-volatile memory. The device includes a 512-bit SHA-1 engine capable of calculating 160-bit Message Authentication Codes (MACs). Data is transmitted serially via the 1-Wire protocol, requiring only one signal line and ground. A single DS1963S can be used for four mutually independent applications, such as secure electronic wallets for local transport systems, pay phones, parking management, or vending machines. It can also act as a co-processor to assist the host in calculating signatures.
The device features a 64-bit laser-etched ROM, a 256-bit scratchpad, 8 pages of 32-byte general-purpose SRAM, 8 write-cycle counter-protected 32-byte SRAM pages, and two 32-byte pages storing eight 64-bit keys. It operates in a temperature range of -20°C to +85°C and retains data for over 10 years. The DS1963S is available in a MicroCan package and supports parasite-powered operation.
