DS1855X-010

The DS1855X-010 is one member of the DS1855 family which is designed as the dual nonvolatile digital potentiometer and secure memory that consists of one 100-position linear taper potentiometer, one 256-position linear taper potentiometer, 256 bytes of EEPROM memory, and a 2-wire interface. And this device allows a user to store configuration or calibration data for a specific system or device as well as provide control of the potentiometer wiper settings.

Features of the DS1855X-010 are:(1)256 bytes of EEPROM memory; (2)Access to data and potentiometer control via a 2-wire interface; (3)External write-protect pin to protect data and potentiometer settings; (4)Data and potentiometer settings also can be write-protected through software control; (5)Nonvolatile wiper storage; (6)Operates from 3V or 5V supplies; (7)Packaging: 14-pin TSSOP, 16-ball STPBGA, flip-chip package; (8)Industrial operating temperature: -40 to +85 ; (9)Programming temperature: 0 to +85 .

The absolute maximum ratings of the DS1855X-010 can be summarized as:(1)Voltage on Any Pin Relative to Ground: -0.3 V to +6.0 V;(2)Operating Temperature Range: -40°C to +85°C; Extended Industrial;(3)Programming Temperature Range: 0°C to +85°C;(4)Storage Temperature Range: -55°C to +125°C;(5)Soldering Temperature: See J-STD-020A Specification.

The electrical characteristics of this device DS1855X-010 can be summarized as:(1)Active Supply Current: 0.5 mA;(2)Input Leakage: -1 to +1 uA;(3)Input Logic 1: 0.7Vcc to Vcc+0.3 V;(4)Input Logic 0: GND-0.3 to 0.3Vcc V;(5)Input Current each I/O Pin: -10 to +10 uA;(6)I/O Capacitance: 10 pF.
