ADVANCED 16-BIT CHMOS MICROCONTROLLER WITH INTEGRATED CAN 2.0

Intel 

87C196CA/87C196CB - Express

2.0

BLOCK DIAGRAM

The MCS 96 microcontroller family members are all high-performance microcontrollers with a

16-bit CPU. The 87C196CB is composed of the high-speed (16 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 communications 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 16 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 structure 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.

Note:

This is an advance information data sheet. The AC and DC parameters contained within this data

sheet may change after full express temperature characterization of the device has been performed.

Contact your local sales office before finalizing the timing and DC characteristics of a design to

verify you have the latest information.
