A new family of 8-bit and 16-bit GPIO devices from NXP Semiconductors features “Agile I/O” – an innovative option integrating the most commonly needed functions in embedded systems. The GPIOs expand ...

The MCP23017, a 16-bit I2C GPIO expander, has always been a tasty chip. With 16 GPIOs addressable over I2C, proper push/pull outputs, software-enabled pull-ups, eight addresses, maskable interrupts ...

Several I2C GPIO expanders will be used to consolidate the I/Os as well as perform the level-shifting function to interface back to legacy devices. In Figure 6 , a dual-supply GPIO expander is used to ...

Blue LEDs are becoming prevalent in the industry and sometimes make their way onto control panels as flashy indicators. Their high forward voltage, however, runs counter to the downward trend in ...

The official Raspberry Pi Foundation has this week announced the release of new GPIO expander software which has been created to provide easy access to the GPIO pins of a Raspberry Pi Zero while ...

Promising to be a cost-effective solution for adding functions while reducing power, the CAT9534 eight-bit GPIO expander targets I2C and SMBus-based systems. The device is pin-for-pin and functionally ...

Diodes has announced the 16-bit PI4IOE5V6416Q and 34-bit PI4IOE5V6534Q bidirectional voltage-level translation general-purpose I/O (GPIO) expanders for automotive applications. In what Diodes claims ...

The ancient Egyptians, Greeks, and Indians were known for attempting to recreate the “Midas touch,” whereby they would practice alchemy in their ongoing quest to find the perfect catalyst to turn lead ...

Figure 1 shows the market size for VR and AR headsets, collectively referred to as extended reality devices, over recent ...
