See all from this product rangeProduct Overview
The DS2431GA+T&R is a 1024bit, 1-wire EEPROM in 2 pin SFN (3.5mm x 6.5mm) package. This chip is organized as four memory pages of 256bit each. Data is written to an 8byte scratchpad is verified and then copied to EEPROM memory. As a special feature, the four memory pages can individually be write protected or put in EPROM emulation mode where bits can only be changed from 1 to 0 state. It communicates over the single conductor 1-wire bus. The communication follows the standard 1-wire protocol. Each device has its own unalterable and unique 64bit ROM registration number that is factory lasered into the chip. The registration number is used to address the device in a multidrop, 1-wire net environment. The device is used in PCB identification, medical sensor calibration data storage, analogue sensor calibration including IEEE P1451.4 smart sensors, ink and toner print cartridge identification and after market management of consumables.
- Reads and writes over a wide voltage range from 2.8V to 5.25V
- Operating temperature range from -40°C to 85°C
- Easily add traceability and relevant information to any individual system
- Individual memory pages can be permanently write protected or put in EPROM emulation mode
- Switchpoint hysteresis and filtering to optimize performance in presence of noise
- Minimalist 1-wire interface lowers cost and interface complexity
- IEC 1000-4-2 level 4 ESD protection (±8KV contact, ±15KV air), 0.4V output low voltage at 4mA
- Communicates to host with single digital signal at 15.4Kbps or 125Kbps
- Recovery time of 5μs (standard speed, RPUP = 2.2Kohm) and 2μs (overdrive speed, RPUP = 2.2Kohm)
- Maximum reset low time of 640μs (standard speed) and 80μs (overdrive speed)
- Accessory/PC Board Identification; After-Market Management of Consumables; Analog Sensor Calibration Including IEEEP 1451.4 Smart Sensors;
- Ink and Toner Print Cartridge Identification; Medical Sensor Calibration Data Storage
