The 87C196CA CB are new members of the MCS 96 microcontroller family These devices are based upon
the MCS 96 Kx Jx microcontroller product families with enhancements ideal for automotive and industrial
applications The CA CB are the first devices in the Kx family to support networking through the integration of
the CAN 2 0 (Controller Area Network) peripheral on-chip The 87C196CB offers the highests memory density
of the MCS 96 microcontroller family with 56K of on-chip EPROM 1 5K of on-chip register RAM and 512
bytes of additional RAM (Code RAM) In addition the 87C196CB provides up to 16 Mbyte of Linear Address
Space The 87C196CA is a sub-set of the CB offering 32K of on-chip EPROM up to 1 0K of on-chip register
RAM and 256 bytes of additional RAM (Code RAM)
