CAN is a development of Robert Bosch GmbH and was designed specifically for high-speed in-vehicle networking. CAN is widely accepted in automotive applications and additionally supports high-speed networking standards such as DeviceNet* and SDS* that are used in industrial control and factory automation. CAN utilizes a multi-master bus configuration for the transfer of communication objects between nodes of the network. |

| Product Overview |
|
Intel has combined the 82527 CAN protocol controller with the industry standard MCS® 96 16-bit microcontroller architecture all on one chip. The result is a family of integrated microcontrollers well suited for a variety of real-time event control applications that require high-speed networking. |
|
|
Integrating CAN on the CPU decreases printed circuit board area, allows faster access to CAN messages and reduces overall system cost. |
|
|
The MCS 96 microcontroller family benefits from a register to register architecture that eliminates the accumulator bottleneck and enables fast context switching. All members of the family have bit, byte, word, and some 32-bit operations. The 87C196CA and 87C196CB microcontrollers with integrated CAN provide an upgrade path for the members of the 87C196Kx/87C196Jx families. |
|
| TN87C196CA |
|
The 87C196CA (datasheet) is a high performance 16-bit microcontroller with integrated CAN 2.0. The feature set is suited for applications requiring real-time event control such as anti-lock braking systems, 4 cylinder engine control, and programmable logic controllers. The 87C196CA is available in a 20 MHz version which offers 25% more performance than the standard product. |
|
|
The on-chip CAN of the 87C196CA is software compatible with the Intel 82527 standalone CAN chip. |
|
|
The 87C196CA expands the 87C196Kx/87C196JX product family by providing a software compatible upgrade path. This integrated microcontroller has memory and a peripheral set similar to the 87C196JT, including 32K Bytes of on-chip OTPROM, 1K Bytes of on-chip register RAM, and 256 Bytes of code RAM. The code RAM may be used to modify critical loops and execute code internally. |
|
|
The cost effective on-chip OTPROM is flexible and allows for quicker time to market and manufacturing flexibility. |
|
|
The peripheral set includes the Event Processor Array (EPA), a high speed I/O unit consisting of 12 modularized units. Six units are pinned out for I/O compare and capture and six are available for internal event timing. It is flexible and provides pulse-width modulation (PWM) generation capability. |

| TN87C196CB |
|
The 87C196CB (datasheet) is a highly integrated superset of the 87C196CA. The 87C196CB provides all of the features of the 87C196CA but has additional memory, more I/O capability and additional features. |
|
|
The 87C196CB provides a compatible upgrade path for 87C196CA applications, such as 4 or 6 cylinder engine control, integrated vehicle dynamics, programmable logic controllers, and motor controls. |
|
|
The 87C196CB offers 56 Kbytes of on-chip OTPROM, 1.5 Kbytes of register RAM, and 512 Bytes of Code RAM. The 87C196CB is capable of addressing up to 1 Mbyte of external memory for high-end applications requiring large off-chip memory. |
|
|
The peripherals and large I/O capabilities of the 87C196CB support applications demanding a full featured microcontroller. The 12 unit EPA has 10 channels pinned out and 2 channels which can be used as internal event timers. The 87C196CB has 56 I/O lines. |
|
|
A new feature on the 87C196CB is the user-selectable 4X PLL clock multiplier which gives the designer greater flexibility in choosing an external clocking source. This can provide for a more cost effective and robust design. For example, designers can use a 5 MHz external crystal or fundamental mode resonator to run a 20 MHz device. |

| NG88CO196EC |
|
The Intel 88CO196EC microcontroller is the first member of the Intel MCSD96 family of microcontrollers with integrated flash memory - on the chip. Integrated flash memory gives designers new capabilities for compact, cost effective solutions in industrial controls, power controllers and industrial engine management applications. |
|
|
The 88CO196EC is highly integrated with an enhanced peripheral set. The integrated CAN 2.0 in-vehicle networking protocol provides for efficient communication to a high-speed CAN bus. The serial debug unit (SDU) provides system debug and development capabilities. The SDU can set a single hardware breakpoint. In addition, the SDU provides read and write access to code RAM through a high-speed, dedicated serial link. A stack overflow/underflow monitor assists in code development by causing a nonmaskable interrupt if the stack pointer crosses a user-defined boundary. The 16-channel A/D converter supports an auto-scan mode that operates with no CPU overhead. Each A/D channel has a dedicated result register. The EPA supports high-speed event captures with 15 programmable, high-speed channels. |
