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 ...
How much can you cram into a 2.6 in x 1.2 in circuit board? You'd presume not much, but the Raspberry Foundation is trying to prove you wrong. First, it added built-in Wi-Fi to its teeny Raspberry Pi ...
Sunnyvale, Calif. —A general-purpose I/O (GPIO) expander has been released that interfaces sixteen 5-V-tolerant I/O ports with microprocessors and microcontrollers through a 400 kHz, 2-wire, SMBus/I 2 ...
The BU1850MUV is a GPIO developed by ROHM Semiconductor. This is used for applications that need to expand their number of IO ports. This IC has a built-in power on reset, 3V tolerant input, and NMOS ...
