DS2432P规格书详情
DESCRIPTION
The DS2432 combines 1024 bits of EEPROM, a 64-bit secret, an 8-byte register/control page with up to 5 user read/write bytes, a 512-bit SHA-1 engine and a fully-featured 1-Wire interface in a single chip. Each DS2432 has its own 64-bit ROM registration number that is factory lasered into the chip to provide a guaranteed unique identity for absolute traceability. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return.
FEATURES
1128 bits of 5V EEPROM memory parti tioned into four pages of 256 bits, a 64-bit write-only secret and up to 5 general purpose read/write registers
On-chip 512-bit SHA-1 engine to compute 160-bit Message Authentication Codes (MAC) and to generate secrets
Write access requires knowledge of the secret and the capability of computing and transmit ting a 160-bit MAC as authorization
Secret and data memory can be write-pro tected (all or page 0 only) or put in EPROM emulation mode (“write to 0”, page 1)
Unique, factory-lasered and tested 64-bit reg istration number assures absolute traceability because no two parts are alike
Built-in multidrop controller ensures compati bility with other 1-Wire net products Reduces control, address, data and power to a single data pin
Directly connects to a single port pin of a mi croprocessor and communicates at up to 16.3k bits per second
Overdrive mode boosts communication speed to 142k bits per second
Low cost 6-lead TSOC surface mount pack age, or solder-bumped Flipchip package Reads and writes over a wide voltage range of 2.8V to 5.25V from -40°C to +85°C
