Key Features |
80C196EA
|
The 8xC196NT has 1 Mbyte external addressability. Four of the A/D inputs were replaced with the Extended Address Port (EPORT). The four EPORT pins can be used as additional address lines (A16 - A19) or standard low speed I/Os or a combination of both. The 8xC196NT has 20 MHz operation. |

|
|
The 8xC196NP offers a dynamically selectable multiplexed/demultiplexed bus. Other key features of the 8xC196NP are the chip select unit, 1 Mbyte addressing, 3 PWM outputs, and 25 MHz operation at 5 volts. |
|
|
The 8xCL196NP is functionally identical with the 8xC196NP, but offers low power operation (3 volts at 13 MHz). |
|
|
The 80C196NU doubles the performance of the 8xC196NP, operating at 50 MHz (5V). The 80C196NU also features a 32-bit accumulator implanted in hardware to increase the performance of multiply/accumulate instructions. The 80C196NU is pin compatible with the 8xC196NP. This feature, along with its clock doubling circuitry, enables the 80C196NU to provide a high performance in-socket upgrade to 8xC196NP designs. Other key features include 1 Mbyte addressing, 3 PWM outputs, the chip select unit, and both 40 and 50 MHz (5V) product offerings. |

The 80C196EA is the first member in the family of microcontrollers targeted at powertrain control in automobiles. Commercial applications include modem, motor-control systems, printers, photocopiers, air-conditioner control systems, disk drives and medical instruments. It operates at 40 MHz and is highly integrated with a large number of peripherals and 4K of RAM. The 80C196EA's demultiplexed address/data bus with 3 chip select outputs make it easier to design low cost memory solutions.
Additional information is available in the 80C196EA product brief. |
