Product Overview

The MCP4551-103E/MS is a single I²C Digital Potentiometer with non-volatile memory. It supports potentiometer wiper configuration and EE memory type. The SCL pin is the serial interfaces serial clock pin. This SCL pin is connected to the host controllers SCL pin. The MCP4551 slave device, so its SCL pin accepts only external clock signals. The SDA pin is the serial interfaces serial data pin. This pin is connected to the host controllers SDA pin. The SDA pin is an open-drain N-channel driver.
  • 8-bit 256 resistors (257 Steps) resistor network resolution
  • Four RAB resistances options - 5, 10, 50 and 100kR
  • Zero to full-scale wiper operation
  • 75R Typical low wiper resistance
  • 50ppm Typical (0 to 70°C) absolute (rheostat) low tempco
  • 15ppm Typical ratiometric (potentiometer) low tempco
  • Non-volatile memory - automatic recall of saved wiper setting
  • WiperLock™ technology
  • 10 general purpose memory locations
  • High-speed read/write to wiper
  • Read/write to EEPROM
  • Write protect to be enabled/disable
  • WiperLock to be enabled/disabled
  • Resistor network terminal disconnect feature via terminal control (TCON) register
  • Reset input pin
  • Hardware write protect (WP) control pin
  • Software write protect (WP) configuration bit
  • 1.5V Typical brown-out reset protection
  • 2.5µA Typical serial interface inactive current
  • High-voltage tolerant digital inputs up to 12.5V
ESD sensitive device, take proper precaution while handling the device.
