C165
Processor Oriented
Microcontroller with
up to 25 MHz CPU Clock
Microcontrollers
The C165* is a processor oriented
version within the Siemens C166
microcontroller family. It meets
the demands of embedded
applications with high-end real-
time requirements and large data
throughput where pricing is a
sensitive factor, for example in
dataprocessing and telecom
products.
The fastest version of the C165,
the SAB-C165-L25M, needs just
80 ns at 25 MHz CPU clock to
process each instruction. The
C165 can operate at voltages
down to 2.7V reducing the power
consumption in battery-powered
applications. Two surface mount
packages are available; MQFP-
100 and TQFP-100.
