For all the people who asked for more information about the Signetics 68070, here is all the information that I have at this time. The SCC68070 is manufactured by Signetics, a subsidiary of U.S. Philips Corporation. Carol Jacobson at Signetics, 811 E. Arques Avenue, P.O. Box 3409, M/S 75, Sunnyvale, CA 94088-3409, telephone 308-991-3682 can provide further information, data sheets, and samples. The part is being sampled now (we have one, but don't have it plugged into anything yet) but is not yet in full production. The part was originally developed for the Philips interactive optical-disk player. Pricing is not yet available but will not be outrageous; this is intended as a component in consumer products. Some additional support, and an evaluation board, may be available from the International Microelectronic Support Center, CTI, 4-16 Avenue du General Leclercm 92660 Fontany-aux-roses, France. This last information comes from someone at Philips Eindhoven (Netherlands). The SCC68070 is program-compatible with the Motorola M68010. It is a CMOS part running at 10 MHz. In addition to the 68010 logic, the chip also contains the following features. - On-chip 2 channel DMA controller - On-chip I2L serial bus interface - On-chip UART - On-chip MMU, supporting virtual memory - Built-in clock generator - 16-bit timer/counter - Two 16-bit match/count/capture registers. Packaging is an 84-pin PLCC. Power consumption is not available at this time. Temperature range is 0C to 70C. Absolute minimum configuration appears to be the SCC68070, a 20MHz crystal, some static RAM, a ROM to get things started, a +5 supply, and a terminal interfaced to CMOS levels. Finding or making a suitable program to put in ROM is probably the hard part. John Nagle

Subject: More on 68070 Keywords: 68070, microcontroler, development systems More information on support for the SCC68070. The support for develpment of applications around a 68070 is sold by the global alliance in Test & Measurement (Fluke and Philips). Contact Tom Nealon or Johan Cranendonk at Philips in Eindhoven, Building TQIII-4, 5600 MD Eindhoven, The Netherlands, tel ++31-40-788054 or ++31-40-788386 for detailed information. General information: The 68070 is supported trough Pascal and C-compilers running on a variaty of hosts (ao VAX ULTRIX, VAX VMS, PC-AT with XENIX, Philips Microprocessor Development system, etc.) including assemblers. Concerning hardware support an incircuit emulator box is available including screen driven software to support the debugging of software even on the level of the language inwhich the program for the 68070 is written in. This software enables you to use in your emulation session the same language as is used to program the application. It includes features to trace variables, structures and procedure calls, handles back-tracing, step at "high level language statement level", software tracing of memory locations and registers, etc. etc.. The hardware of this Micro processor Adaptor Box (MAB) allows for four hardware break and/or trigger registers, to be used seperately or armed, generating either a break, a pulse or a signal to qualify data capturing. Processors memory can be addressed logicaly or physically (before or after the build in MMU. Memory can be mapped in segments and be declared as RAM, ROM or guarded. Clock source can be derived from an internal or external cristal or from the prototype. Emulation break can be selected from a wide range to be switched on or off (power fail, reset active, halt-line active, not ready, etc.). The MAB 68070 is to be connected to a host system this can be an IBM-PC-AT or compatible running Xenix or a Philips propriatry host (68000 -based) running Unix(TM).
