DEI1160A 数据手册

Serial Interface

The DEI1160A incorporates a serial IO interface for programming the Discrete Input configuration and for reading the

Discrete Input status. Refer to Figure 2. The interface is SPI compatible and consists of /CS, SEL, SCLK, SDO, and SDI

signals. Waveform Figures 4 – 7 depict the Data Read sequence and Configuration Write sequence for both 8-Bit cycles and

also 16 bit “daisy chain” applications.

Power Up Initialization

The DEI1160A incorporates an on-chip power-up reset circuit and power sequencing provisions to force the DIN inputs to the

28V/Open (internal pull down) state upon power. The reset circuit monitors the VCC logic supply and forces the

Configuration Register to the Logic 0 (28V/Open) while VCC is stabilizing. The AFE circuit is designed to present the

28V/Open (internal pull down) condition when VDD supply is present and VCC is below operational voltage.
