80C196EA Microcontroller Product Brief

Overview
The 80C196EA is the first member in the family of microcontrollers targeted at powertrain control in automobiles. Commercial applications include modem, motor-control systems, printers, photocopiers, air-conditioner control systems, disk drives and medical instruments. It operates at 40 MHz and is highly integrated with a large number of peripherals and 4K of RAM. The 80C196EA's demultiplexed address/data bus with 3 chip select outputs make it easier to design low cost memory solutions.

A new Serial Debug Unit (SDU) featured on the 80C196EA allows the contents of the code RAM to be read and written without CPU overhead via a high-speed dedicated serial link. A single hard-ware breakpoint may also be set via the SDU.

For high speed event capture and output compare, the 80C196EA has 17 flexible Event Processor Array (EPA) channels and 8 output only modules. These output only modules are new to the C196 Family and have the ability to capture a timer when the compare occurs. There are four independent timer/counters on the 80C196EA.

A new analog to digital converter is implemented on the 80C196EA. This 16 channel 10-bit ADC has a dedicated result register for each channel. Each channel can be individually selected for inclusion in an auto-scan mode which operates without CPU overhead. The most recent conversion result is always available in the channel's result register in this mode.

To assist with inter-processor communications the 80C196EA has two UARTs and two half-duplex synchronous serial ports. Each UART has its own baud rate generator for flexibility. The synchronous serial port is enhanced from previous implementations in that the user has full control over the clock phase and polarity. Support for multi-master systems has been added to the synchronous serial ports.

Eight pulse width modulator units are also on the 80C196EA. Each unit has eight-bit resolution and is capable of frequencies ranging from 244 Hz to 62.5 KHz with a 32 MHz clock.

The 80C196EA can perform stack limit checking in hardware to assist in code development and help insure system integrity.
