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.
8xL196NP
The 8xCL196NP is functionally identical with the 8xC196NP, but offers low power operation (3 volts at 13 MHz).
80C196NU
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.

80C196EA
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.
