A high-performance MCSÉ 96 microcontroller family members, the 80C196KC 16-bit microcontroller is a part of the MCSÉ 96 family. The 80C196KC is an improved version of the 80C196KB device. It features 488 bytes of RAM, the ability to operate at 16 or 20 MHz, and an additional 16 kilobytes of ROM or OTPROM as an option. Intel’s CHMOS III manufacturing process results in a processor with excellent performance and low power consumption.

The 87C196KC is an 80C196KC with an on-chip OTPROM 16 kilobytes in size. The 83C196KC is an 80C196KC with 16 bytes of ROM added by the manufacturer. The 80C196KC shall refer to all products throughout this text unless otherwise specified. Four high-speed capture inputs are available for recording timestamps whenever events occur. Six high-speed outputs can be used for the creation of pulses or waveforms. Additionally, the high-speed output can initiate an analog-to-digital conversion or generate four software timers.

The timer or the up/down counter can serve as the basis for events. When the commercial temperature option is used, the operational parameters are guaranteed to be stable over the temperature range of 0 degrees Celsius to 70 degrees Celsius. Operation characteristics are secured over a temperature range of -40 to 85 degrees Celsius when the extended temperature range option (Express) is used. The specifications are the same for both choices unless specifically stated otherwise.

What is Intel MCS-96?

Embedded systems frequently use the microcontrollers (MCUs) that belong to the Intel MCS-96 series. The family is commonly known as the 8xC196 family, also written as 80196, and is the most well-known MCU in the family. MCUs are frequently used in modems, hard disk drives, printers, motor control systems, and pattern recognition. In 2007, Intel announced that it would no longer produce any microcontrollers belonging to the MCS-96 family. Intel stated, “There are no direct substitutes for these components, and a redesign will most certainly be necessary.”

The MCS-96 family was initially developed as a commercial variant of the Intel 8061. The Intel 8061 was the first CPU used in the Ford EEC-IV engine controller series. One of the critical distinctions between the 8061 and the 8096 is the memory interface bus. The M-Bus of the 8061 is a “burst-mode” bus, which necessitates the presence of a tracking program counter in the memory devices. There were also substantial differences between the input and output peripherals of the two distinct components.

An effort was made for sharing pins between the EEC-IV and the 8096 to reduce the total number of input and output pins and make better use of the pins for a memory interface bus that is more standard. This is the fundamental reason the two chips have so many differences. In addition, unlike the 8061, the 8096 featured on-chip program memory. This memory was not present in the 8061.

In 1982, Ford established the Ford Microelectronics laboratory in Colorado Springs to propagate the EEC-IV family, develop further bespoke circuits for use in autos, and investigate the gallium arsenide integrated circuit industry. Components belonging to this family included the 8065, which had a memory controller built into it and allowed it to address one megabyte of memory.

Although the series of microcontrollers only has 16 bits, it can perform some 32-bit tasks. The CPUs have clock speeds of 16, 20, 25, and 50 MHz and are organized into three smaller families. The HSI (high-speed input) and HSO (high-speed output) families work at 16 and 20 MHz, whereas the EPA (event processor array) families function at all of the frequencies.

The MCS-96 family includes a large on-chip memory, three operand instructions, a Register-to-register architecture, a bus controller that allows for either an 8-bit or 16-bit bus width, and direct flat addressability of large blocks (256 or more) of registers. These features are the primary distinguishing characteristics of the family.
