Preface

Microcontrollers from Philips Semiconductors

Philips Semiconductors supplies a wide range of microcontrollers based on mainstream architectures. By offering a large variety of product derivatives, Philips Semiconductors can meet a broad range of specific or unique application requirements. All of our microcontrollers are based on mainstream architectures to allow the user to take advantage of existing software and a vast array of third-party support.

Philips Semiconductors 8-bit microcontrollers are based on the popular 80C51 and 80C49 architectures. We offer most

01

the industry standard products in these architectures as well as a large selection of powerful derivative products. These derivatives offer a wide assortment of features, including: additional memory,

AID,

PWM, additional timers, and many more. Many of the derivative microcontrollers have an 1²C serial interface that allows them to be connected easily to over 70 other parts, increasing their capabilities even further. The FC serial bus is covered in Section 2 of this book. This data book covers the 80C51 standard products and derivatives that Philips Semiconductors manufactures. The 80C49 products are covered in a separate book.

Philips Semiconductors 16-bit microcontroller family is based on the powerful 68000 architecture. While these are called 16-bit microcontrollers, the 68000 CPU core architecture is 32-bit. This offers the user a great deal more processing power, when the need arises in a design to move from an 8-bit to a 16-bit microcontroller.

Philips Semiconductors 16-bit microcontrollers are software compatible with existing 68000 code. As with our popular 8-bit microcontrollers, EPROM and OTP versions of our 16-bit products are available. The 16-bit microcontrollers are also covered in a separate data book.

Philips Semiconductors is developing a family of 32-bit microcontrollers based on the SPARC RISC architecture. This family of microcontrollers will offer the ultimate in processing power for those applications that are computation intensive in an embedded control environment.

Philips Semiconductors offers uncompromising quality, service, and support with all of its microcontroller products. For a complete family and the best in microcontroller products, look to Philips Semiconductors.
