NXP Introduces Industry’s First I2C-Bus Controllers Supporting New Ultra Fast-Mode Specification
Invented by NXP (formerly Philips Semiconductors) over 30 years ago, the I²C bus has revolutionized chip-to-chip communications by replacing complex parallel interfaces with a straightforward yet powerful serial structure using a simple two-wire format. The I²C bus continues to be used extensively for system management and control in computing and enterprise equipment, and in portable and consumer applications, where it shrinks the IC footprint and leads to lower system costs. Operating at speeds of up to 5 MHz, the new Ultra Fast-mode (UFm) is a uni-directional push-pull serial bus ideally suited for driving LED controllers and other devices that do not require feedback. With its newest UFm and Fm+ bus controllers, NXP is significantly enhancing I²C performance for gaming systems such as Japanese pachinko and slot machines, by improving management of large, complex data transfers, and enabling stronger resistance to electrical shock attacks.
