1 / 82 page  COM20051 Integrated Microcontroller and ARCNET (ANSI 878.1) Interface FEATURES • High Performance/Low Cost • Microcontroller Based on Popular 8051 Architecture • Intel 8051 Instruction Set Compatible • Drop-In Replacement for 80C32 PLCC • Network Supports up to 255 Nodes • Powerful Network Diagnostics • Maximum 507 Byte Packets • Duplicate Node ID Detection • Self-Configuring Network Protocol • Retains all 8051 Peripherals Including Serial I/O and Two Timers • Utilizes ARCNET Token Bus Network Engine • Requires No Special Emulators • 5 Mbps to 156 Kbps Network Data Rate • Network Interface Supports RS-485, Twisted Pair, Coaxial, and Fiber Optic Interfaces • Receive All Mode Allows Any Packet to Be Received GENERAL DESCRIPTION The COM20051 is a low-cost, highly-integrated microcontroller incorporating a high-performance network controller based on the ARCNET Token Bus Standard (ANSI 878.1). The COM20051 is based around the popular Intel 8051 architecture. The device is implemented using a microcontroller core compatible with the Intel 80C32 ROMless version of the 8051 architecture. The COM20051 is ideal for distributed control networking applications such as those found in industrial/machine controls, building/factory automation, consumer products, instrumentation and automobiles. The COM20051 contains many features that are beneficial for embedded control applications. The microcontroller is a fully-functional 16MHz 80C32 that is comparable to the Intel 80C32 with 2 timers. In contrast to other embedded controller/networking solutions, the COM20051 adds a fully-featured, robust, powerful, and simple network interface while retaining all of the basic 8051 peripherals, such as the serial port and counter/timers. In addition, the COM20051 supports an Emulation Mode that permits the use of a standard 80C32 emulator in conjunction with the COM20051 to develop software drivers for the network core. ARCNET core is mapped to a 256-byte page of the External Data Memory Space of the 80C32. This |
