As one of the most popular buses today for on- and inter-board communication within systems, there’s a good chance you’ll end up using it with an embedded system. I2C offers a variety o… ...

Since one register contains 8 bits and we have 16 GPIOs, there are two registers per feature, and as such, there are two registers for pin directions, two for enabling integrated pullups, two for ...

Data arriving through either an I2C or SMBus serial bus sets the state of up to 16 individual LEDs, an oscillator, and two internal timers. LEDs can be set to ‘on’, ‘off’ or ‘flash’, with the flash ...

The LTC4303 and LTC4304 two-wire bus buffers from Linear Technology solve the common problem of a stuck I2C/SMBus bus ... it will automatically generate up to 16 clock pulses on the SCLOUT pin in ...

Continuing its support for the venerable microcontroller-oriented Inter-IC (12C) and SMBus protocols, Texas Instruments Inc. has released three new 16-Bit Configurable I2C and SMBus I/O expanders. The ...

This does require an extra package pin, and prohibits the use of most I2C devices (without the extra pin) at the isolated SideB bus. This also complicates debugging of the bus because most I2C bus ...

Assuming position as the smallest available, the 8-bit MAX5548 and 10-bit MAX5550 dual d/a converters measure 3 mm x 3 mm in TQFN packages. Despite their size, the devices manage ...
