VT2848 | VT2848 FPGA

The module VT2848 provides 48 inputs or outputs for digital signals. They may be connected directly to the inputs or outputs of an ECU. Also, other digital signals can be measured or controlled using this module, e.g. to control additional parts of a test bench.

This module is also available as a variant (VT2848 FPGA) with user programmable FPGA.

General-Purpose Digital I/O Module: VT2848 | VT2848 FPGA

Functions for Each Channel

Channel individually configurable as input or output channel
Sampling of digital input signals with configurable threshold
Determination of frequency and duty cycle of PWM signals (on 16 channels)
3 modes for digital output:
- Push-pull operation against V_batt or V_ext
- Low-side switch
- High-side switch against V_battor V_ext
Outputs use transistors to allow endurance tests
Autonomous output of a bit stream loaded into module
Generation of a PWM signal (on 16 channels)
