Semiconductors (HL) For the trade and technical press February 1997 CAN 2.0B: new stand-alone and 8-bit controllers for the lower price category The great success of the CAN (Controller Area Network) goes on unabated: there are worldwide more than 15 million subscribers linked via the CAN protocol and their numbers are growing day by day. The reasons for this lie in the good transmission rate and high flexibility and profitability of the network. To be able to offer performance at the right price to the users of CAN 2.0B Siemens have now extended their family of CAN microcontrollers by two new members: the 8-bit microcontroller C505C C505C and the stand-alone CAN controller SAE 81C92 81C92. The two components thus round off the line of CAN controllers in the lower price category. The C505C C505C is a fast, compact 8-bit microcontroller in MQFP44 MQFP44 package with FullCAN 2.0B, AD converter, 16-Kbyte ROM, 512-byte RAM, 300-ns cycle time and comprehensive fail-save features as well as power-save functions. Its price corresponds to that of available stand-alone types without a controller. This makes the microcontroller highly interesting for applications where CANs were ruled out so far because of cost considerations. Such applications range from communication between industrial control systems, simple office networks to building installations and monitoring systems. The 125°C version fully meets the requirements of the automotive industry, e.g. for door control modules in car electronics or for intelligent sensors in monitoring the oil quality. The SAE 81C92 81C92 is based on the experience gained with previous members of the Siemens CAN microcontroller family: The stand-alone CAN controller SAE 81C92 81C92 uses the CAN module integrated in the C515C C515C and C505C C505C and proven million-fold in the field as part of the C167CR C167CR. The maximum baud rate of 1 Mbaud is attained already at the operating frequency of 8 MHz. The FullCAN module offers 15 message buffers and supports both the 11-bit standard protocol and the extended version with 29 bits. The SAE 81C92 81C92 can be controlled by any processor via a multiplex or demultiplex address/data-bus interface. This flexibility opens up application fields that -2Siemens AG Corporate Communications Corporate Press Office D - 80312 Munich Tel.

The SAE 81C92 81C92 too comes in a MQFP44 MQFP44 package. Samples of the C505C C505C and SAE 81C92 81C92 are now available. Series production will start in the middle of 1997. With the new components Siemens are bringing out six different controllers. The controllers all support CAN 2.0B and, as stand-alone, 8-bit or 16-bit modules, offer price/performance ratio to match the specific requirements. The success story is by no means over: Siemens are planning to introduce further CAN derivates to the ma rket this year.
