87C196JT Product Brief

The 87C196JT is a high memory, high performance member of the 87C196Kx/Jx 16-bit microcontroller family. The large 32 Kbyte EPROM program memory and 1.5 bytes on-chip RAM provides the large memory storage demanded by today's software algorithms.

The 87C196JT is a high performance member of the industry standard, Intel MCS(R) 96 microcontroller family. The 87C196JT provides the high memory integration of the MCS 96 microcontroller family, having 32 Kbyte of on-chip EPROM memory, 1 Kbyte of register RAM, and 512 bytes of code RAM. The 87C196JT is a pin-to-pin compatible memory upgrade from the 87C196JR. The register architecture of the MCS 96 microcontroller family eliminates accumulator bottleneck and enables fast context switching which increases execution time of C programs. The 512 bytes of code RAM can be used to modify critical loops and execute code internally. The 87C196JT has bit, byte, word, and some 32- bit instructions and is available in 16 MHz and 20 MHz versions. The high performance microcontroller is capable of 16 x 16-bit multiply in 1.75µ S, and 32/16-bit divide in 3µS when operating at 16 Mhz.

The 87C196JT has a complete enhanced set of integrated peripherals and is available in a low-cost 52 lead PLCC package. It offers a six channel A/D with 8- or 10-bits of resolution. The 87C196JT has a configurable 8- or 16-bit bus. The 87C196JT has 12 modularized high speed I/O units called the Event Processor Array (EPA). Six units are pinned out for I/O event compare and capture and six are available for internal event timing.

The 87C196JT offers a Peripheral Transaction Server (PTS), which is an alternative way to service an interrupt, reducing latency and overhead, similar to a DMA. The PTS is capable of handling single and block transfers, A/D conversions, and EPA events without executing an interrupt service routine.The 87C196JT has 41 I/O lines, 2 serial ports, a watchdog timer, two 16-bit timers, and oscillator fail detect circuitry. Intel's CHMOS process technology combines low power consumption and high performance. Idle and powerdown modes are available to further reduce power consumption.
