The 87C196Kx devices represents the 4th generation of MCSÉ 96 microcontroller products implemented on Intel’s advanced 1 micron process technology. These products are based on the 80C196KB device with enhancements ideal for automotive applications. The instruction set is a true super set of the 80C196KB with a few new instructions. The MCS 96 microcontroller family members are all high performance microcontrollers with a 16-bit CPU. The 87C196KT is composed of the high speed (16 MHz) KX macrocore as well as the following peripherals: Up to 32 Kbytes of Program EPROM, up to 1 Kbytes of Register RAM (00-3FFH including SFRs), up to 512 bytes of code RAM (16-bit addressing modes) with the ability to execute from this RAM space, an eight channel-10 Bit g3LSB analog to digital converter with programmable S/H times with conversion times k20 ms at 16 MHz, an asynchronous/synchronous serial I/O port (8096 compatable) with a dedicated 16-bit baud rate generator, an additional synchronous serial I/O port with full duplex master/slave transceivers, a flexible timer/counter structure with prescaler, cascading, and quadrature capabilities, 10 modularized multiplexed high speed I/O for capture and compare (called Event Processor Array) with 250 ns resolution and double buffered inputs, and a sophisticated prioritized interrupt structure with programmable Peripheral Transaction Server (PTS). The PTS has several channel modes, including single/burst block transfers from any memory location to any memory location, a PWM and PWM toggle mode to be used in conjunction with the EPA, and an A/D scan mode. Additional SFR space is allocated for the EPA and can be ‘‘windowed’’ into the lower Register RAM area.
