Texas Instruments has officially unveiled the MSPM0C1104, which it claims to be the world's smallest microcontroller. This remarkable device measures a mere 1.38 mm², which is only slightly larger ...

There are of course a few other ways to find some more lines on a Pi and indeed almost any microcontroller, with one of the many types of GPIO expansion chips. This trick is a particularly ...

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 ...

Raspberry Pi Pico microcontrollers come with a variety of different features for a few bucks, and a few interesting ...

There can be several GPIO pins that depend on the application of the chip. Figure 1: GPIO in a System The pins can be programmed as input, where data from some external source is being fed into the ...

Yes there are multiple variants of the System on Chip used in the newly released Raspberry Pi Pico 2. The RP2350A has support for only 30 GPIO pins while the RP2350B can support up to 48 GPIO.

This flip-chip compatible library in Dongbu HiTek 130nm features a fail-safe GPIO, two standard GPIOs, a 5V GPI, and 5V I2C-compliant ODIO. The GFGPIO is a highly configurable 5V tolerant, ...
