C515A
Microcontroller for
Standard Applications
Microcontrollers
The Siemens C515A improves
the well known microcontroller
family SAB 80C515A and SAB
80C515 in terms of performance
and technology without loosing
compatibility to the standard
product.
The optimized C500-Kernel with
an Instruction cycle of 500ns
(external clock rate of 24Mhz),
features standard peripherals
like 10-Bit A/D Converter, 4
Capture/Compare channels and
other multipurpose peripherals.
Enhanced functionality in terms
of getting overall Power
consumption and EMC down,
like ALE switchoff, Wakeup from
Power-Down via Interrupt and
other up-to-date improvements
are integrated in an optimized
microcontroller solution.
The C515A fits into most of to-
days applications and is a good
solution to realize control in the
Consumer and Industrial market.
