The 8xC196KB is the first member of the CHMOS* MCS® 96 controller family. It is available in CPU only 8K byte ROM, and 8K byte OTPROM versions. All versions feature 232 bytes of register RAM.
The 8xC196KB uses the High-Speed Input/Output (HSIO) structure for event control. The HSIO has up to 4 input and 6 output lines, and uses either of two 16-bit timer/counters as a time base.
Additional features include a hardware-generated Pulse Width Modulator (PWM), a full-duplex Serial I/O (SIO) port, a watchdog timer and an 8-channel 10-bit resolution Analog to Digital (A/D) converter. The 8xC196KB has 48 Input/Output (I/O) lines which are shared with the peripherals.
8xC196KC
The 8xC196KC is the next step up in the CHMOS 196 family. It is available in CPU 16K byte ROM and 16K byte OTPROM versions. All versions feature 488 bytes of Register RAM. The 8xC196KC is offered in a 20 MHz version, allowing an immediate 25% increase in performance. The 8xC196KC has all the same peripherals as the 8xC196KB, but adds the following features:
There are now a total of three hardware PWM generators, the A/D converter has both 8- and 10-bit conversion modes with programmable sample and conversion times, and a Peripheral Transaction Server (PTS) has been added. The PTS acts as a microcoded interrupt handler which greatly reduces CPU overhead during interrupt servicing.
8xC196KD
The 8xC196KD has all the features of the 8xC196KC, but has extended the on chip memory. The 8xC196KD is available in 32K byte ROM and 32K byte OTPROM versions. Both versions feature 1000 bytes of Register RAM. With the availability of 32K of memory, progr am development in high level languages becomes much more practical. The 8xC196KD is also offered in a 20 MHz version.
