MAX7219CWG+T

Display Drivers Overview

The MAX7219CWG+T is a serially interfaced, 8-digit LED display driver manufactured by Analog Devices Inc./Maxim Integrated. It integrates a BCD decoder, multiplexing scan circuitry, segment drivers, and an 8x8 static RAM for data storage. The device operates on a single 4V to 5.5V supply with a maximum power supply current of 330mA. It supports SPI, QSPI, and MICROWIRE interfaces and features digital/analog brightness control.

Display Drivers Feature Summary

• Serial interface compatibility with standard microprocessors
• Integrated BCD decoder and multiplexing scan circuitry
• Digital and analog brightness control capabilities
• Low-power shutdown mode for energy efficiency

Display Drivers Applications

• High-voltage interrupt displays
• Bar graph displays
• Instrument panel indicators
• Industrial control systems

Display Drivers Procurement Notes

Verify the specific suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the SOIC-24 package variant matches the target PCB footprint requirements before finalizing procurement orders.

Display Drivers Selection Notes

Select this component for designs requiring direct microprocessor connection to multiple 7-segment LEDs without external decoding logic. Consider the SOIC-24 surface-mount package for automated assembly processes. Evaluate thermal dissipation needs given the 330mA maximum supply current specification during operation.

Display Drivers Part Context

This part belongs to the MAX7219 family of LED display drivers from Maxim Integrated. It serves as a cost-effective solution for managing complex LED matrix or multi-digit numeric displays. The CWG suffix specifically denotes the commercial temperature range and wide SOIC package type within the product line.

Display Drivers Replacement Considerations

MAX7219EWG+T offers the same functionality but supports an extended industrial temperature range (-40°C to +85°C). Verify pinout compatibility and software register definitions remain identical before substituting components in existing designs.
