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)
87C196CA 87C196CB
The MCS 96 microcontroller family members are all high-performance microcontrollers with a 16-bit CPU The
87C196CB is composed of the high-speed (20 MHz) macrocore with up to 16 Mbyte linear address space 56
Kbytes of program EPROM up to 1 5 Kbytes of register RAM and up to 512 bytes of code RAM (16-bit
addressing modes) with the ability to execute from this RAM space It supports the high-speed serial commu-
nications protocol CAN 2 0 with 15 message objects of 8 bytes data length an 8-channel 10-bit
3 LSB
analog to digital converter with programmable S H times and conversion times
k
20 ms at 20 MHz It has an
asynchronous synchronous serial I O port (SIO) with a dedicated 16-bit baud rate generator an additional
synchronous serial I O port (SSIO) with full duplex master slave transceivers a flexible timer counter struc-
ture with prescaler cascading and quadrature capabilities There are ten modularized multiplexed high-
speed I O for capture and compare (called Event Processor Array) with 200 ns resolution and double buffered
inputs and a sophisticated prioritized interrupt structure with programmable Peripheral Transaction Server
(PTS) implementing 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
