Intel MCS-96
TheIntel MCS-96is a family ofmicrocontrollers(MCU) commonly used inembedded systems.The family is often referred to as the 8xC196 family, or 80196, the most popular MCU in the family. These MCUs are commonly used inhard diskdrives,modems,printers, pattern recognition andmotor control.In 2007,Intelannounced the discontinuance of the entire MCS-96 family of microcontrollers. Intel noted that "There are no direct replacements for these components and a redesign will most likely be necessary."[1]
History[edit]
The MCS-96 family originated as a commercial derivative of theIntel 8061,the first processor in theFord EEC-IVengine controller family. Differences between the 8061 and the 8096 include the memory interface bus, the 8061's M-Bus being a 'burst-mode' bus requiring a tracking program counter in the memory devices. There were also considerable differences in the I/O peripherals of the two parts – the 8061 had 8 HSI (pulse-measurement) inputs, 10 HSO (pulse-generation) outputs entirely separated from the HSI pins, and a non-sampling 10-bit ADC with more channels than the 8096 had. Many differences between the EEC-IV and the 8096 resulted from an effort to share pins to reduce I/O pin count in favor of using the pins for a more conventional memory interface bus. The 8096 also had on-chip program memory lacking in the 8061.
Ford created the Ford Microelectronics facility in Colorado Springs in 1982 to propagate the EEC-IV family, develop other custom circuits for use in automobiles, and to explore thegallium arsenideintegrated circuit market. Parts in that family included the 8065, which incorporated a memory controller allowing it to address a megabyte of memory.
The family of microcontrollers are16-bit,however, they do have some32-bitoperations. The processors operate at 16, 20, 25, and 50MHz,and are separated into 3 smaller families. The HSI (high speed input) / HSO (high speed output) family operates at 16 and 20 MHz, and the EPA (event processor array) family operates at all of thefrequencies.
The main features of the MCS-96 family include a large on-chip memory,Register-to-register architecture,threeoperandinstructions,buscontroller to allow 8- or 16-bit bus widths, and directflat addressabilityof large blocks (256 or more) ofregisters.
809x/839x/879x family[edit]
The 809x/839x/879x ICs are members of the MCS-96 family. Although MCS-96 is thought of as the 8x196 family, the 8095 was the first member of the family. Later the 8096, 8097, 8395, 8396, and 8397 were added to the family.
TheIntel809x/839x/879x ICs are 12MHz,16-bitmicrocontrollers.Themicrochipis based on a 5V,3 micrometre,HMOSprocess. The microcontroller has an on-chipALU,4 channel 10-bitanalog-to-digital converter(ADC), 8-bitpulse width modulator(PWM),watchdog timer,4 16-bit software timers,hardware multiplyand divide, and 8 KB of on-chipROM.The 8095 is ROMless and has five 8-bit high speedI/O,fullduplexserial port[clarification needed],as well as an ADC input and PWM output.
The 8095 comes in a 48-pinCeramicDIPpackage,and the following part number variants. C8095-90
8x196/8xC196 family[edit]
The MCS-96 family is generally thought of as the 80C196 IC, even though the family includes the 809x/839x/879x microcontrollers, which came first. Members of this sub-family are 80C196, 83C196, 87C196 and 88C196.
Other vendors[edit]
As of 2021, microcontrollers using the MCS-96 architecture are still being manufactured byNIIETinVoronesh,Russia, as the 1874 series of integrated circuits. This includes aradiation-hardeneddevice with aSpacewireinterface under thedesignation1874VE7T (Russian:1874ВЕ7Т).[2]Cobham(formerlyAeroflex) manufactured another radiation-hardened MCS-96 microcontroller until about 2020.[3]
