 Dobry den. Vy nemate pristup na internet? Skusil som do hotbotu dat subject a vyplul mi hned 29
zasahov. A to som neskusal ine vyhladavace.

The COP8780, COP8781 and COP8782 (COP878x family) are members of the
COP8 Basic Family that contain EPROM, RAM, a 16-bit multi-function timer with a
single 16-bit auto-reload/capture register, 3 interrupt sources with polling scheme,
and the MICROWIRE/PLUS TM serial interface. These devices are offered in 20-pin
SO/DIP, 28-pin SO/DIP, 40-pin DIP, and 44-pin PLCC. The operating voltage range
is from 4.5V to 6.0V. The COP8SAA7, COP8SAB7 and COP8SAC7 (COP8SAx7
family) devices, on the other hand, are members of the COP8 Feature Family that
contain EPROM, RAM, a 16-bit multi-function timer with two auto-reload/capture
registers, eight interrupt sources supporting vectored interrupt scheme, and the
enhanced MICROWIRE/PLUS serial interface. In addition, these devices contain
features such as Multi-Input Wakeup, WATCHDOG TM /Clock Monitor, Idle timer
supporting Idle mode, internal Power-On Reset, on-chip RC oscillator, 8 bytes of
user storage space in EPROM, and on-chip EMI reduction circuitry. The devices
are offered in 16-pin SO/DIP, 20-pin SO/DIP, 28-pin SO/DIP, 40-pin DIP, and 44-pin
PLCC. The operating voltage range is from 2.7V to 5.5V. See the datasheet for
more details. The purpose of this Application Note is to provide a detailed
comparison and feature analysis of these two family of devices. Where applicable,
this report can be used to assist in converting the code written for the COP878x
device to operate on an equivalent COP8SAx7 device. As suggested, the
COP8SAx7 family offers a broad range of additional useful and enhanced features
as compared to the COP878x family. With the additional features, the COP8SAx7
family may appear much different, but this family is designed to maintain downward
compatibility with the COP878x family as much as possible. The intention has been
to offer the COP878x user the capability to maintain the same PCB when
converting to COP8SAx7 without any PCB changes.
