Nonvolatile Memory (EEPROM): - User-programmed Power-on Reset (POR)/Brown-out Reset (BOR) output setting General Description recall and device configuration bits The MCP47FEBXX are Single- and Dual-channel 8-bit, - Auto Recall of Saved DAC register setting 10-bit, and 12-bit buffered voltage output Digital-to- - Auto Recall of Saved Device Configuration Analog Converters (DAC) with nonvolatile memory and (Voltage Reference, Gain, Power-Down) 2 an I C serial interface. Power-on/Brown-out Reset Protection The V pin, the device V or the internal band gap REF DD Nonvolatile Memory Write Protect (WP) Bit voltage can be selected as the DACs reference Power-Down Modes: voltage. When V is selected, V is connected DD DD - Disconnects output buffer (High Impedance) internally to the DAC reference circuit. When the V REF - Selection of V pull-down resistors pin is used, the user can select the output buffers gain OUT (100 k or 1 k ) to be 1 or 2. When the gain is 2, the V pin voltage REF should be limited to a maximum of V /2. Low Power Consumption: DD 2 - Normal operation: <180 A (Single), 380 A These devices have a two-wire I C-compatible serial (Dual) interface for Standard (100kHz), Fast (400 kHz) or High-Speed (1.7 MHz and 3.4 MHz) modes. - Power-down operation: 650 nA typical - EEPROM write cycle (1.9 mA maximum) 2 Applications I C Interface: - Slave address options: four predefined Set Point or Offset Trimming addresses or user programmable (all 7 bits) Sensor Calibration - Standard (100 kbps), Fast (400 kbps), and Low-Power Portable Instrumentation High-Speed (up to 3.4 Mbps) modes PC Peripherals Package Types: 8-lead TSSOP Data Acquisition Systems Extended Temperature Range: -40C to +125C Motor Control 2015 Microchip Technology Inc.
