Philips Semiconductors 2 The I C-bus and how to use it (including specifications) 1995 update 2 1.0 THE I C-BUS BENEFITS DESIGNERS AND 1.1 Designer benefits 2 MANUFACTURERS I C-bus compatible ICs allow a system design to rapidly progress In consumer electronics, telecommunications and industrial directly from a functional block diagram to a prototype. Moreover, electronics, there are often many similarities between seemingly since they ‘clip’ directly onto the I2C-bus without any additional unrelated designs. For example, nearly every system includes: external interfacing, they allow a prototype system to be modified or upgraded simply by ‘clipping’ or ‘unclipping’ ICs to or from the bus. • Some intelligent control, usually a single-chip microcontroller Here are some of the features of I2C-bus compatible ICs which are • General-purpose circuits like LCD drivers, remote I/O ports, RAM, particularly attractive to designers: EEPROM, or data converters • Functional blocks on the block diagram correspond with the actual • Application-oriented circuits such as digital tuning and signal ICs; designs proceed rapidly from block diagram to final processing circuits for radio and video systems, or DTMF schematic generators for telephones w
