We’re always excited to get a new chip or SIM card to interface, but our enthusiasm is often dampened by the prototyping process. Interfacing any chip usually means breadboarding a circuit, writing ...

The digital compensation posts covered all the control aspects of building a switch mode power supply, but did not cover external communication and control. This post will demonstrate how to write ...

In my last column [LJ, December 2003], we discussed how I2C bus drivers and I2C algorithm drivers work. We also described how to make a tiny dummy I2C bus driver. This month, we discuss how an I2C ...

Microchip Technologies’ 24AA52 is a 2Kbit electrically erasable PROM capable of operation across a broad voltage range. It has a software write-protect feature for the lower half of the array, as well ...
