Automotive — 87C196CA 18 MHz Microcontroller
1.0
Introduction
Table 1.
The MCS 96 microcontroller family members are all high performance microcontrollers with a
16-bit CPU.
The 87C196CA family members are composed of the high-speed (18 MHz) core as well as the
following peripherals:
• 32 Kbytes of Programmable EPROM
• 1.0 Kbytes of register RAM and 512 bytes of code RAM (16-bit addressing modes) with the
ability to execute from this RAM space
• Six–10-Bit/ ± 3 LSB analog to digital converter with programmable S/H times with
conversion times < 5 µs at 16 MHz
• An asynchronous/synchronous serial I/O port (8096 compatible) with a dedicated 16-bit baud
rate generator
• Interprocessor communication slave port
• Synchronous serial I/O port with full duplex master/slave transceivers
• A flexible timer/counter structure with prescaler, cascading, and quadrature capabilities
• Six modularized multiplexed high speed I/O for capture and compare (called Event Processor
Array) with 250 ns resolution and double buffered inputs
• 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.
• Serial communications protocol CAN 2.0 with 15 message objects of 8 bytes data length
The 87C196CA device is a member of the fourth generation of MCS® 96 microcontroller products
implemented on Intel’s advanced 1 micron process technology. This product is based on the
80C196KB device with improvements for automotive applications. The instruction set is a true
super set of 80C196KB.
The 87C196CA device is a memory scalar of the 87C196KR in a 68-pin package with 32 Kbytes of
on-chip EPROM, 1.0 Kbytes of register RAM, and 256 bytes of code RAM. In addition, the
87C196CA contains an extra peripheral for serial communications protocol CAN 2.0.
Table 1 summarizes the features of the 87C196CA device.
