DescriptionSiemens C165 16-Bit Microcontroller.The C165’s technology, originally a 5 V technology, allows to run the device at supply voltages down to 2.7 V. This addendum specifies the characteristics of the C165 when operated at 3 V. The input and output levels are still TTL compatible, the power supply current is reduced. The timing characteristics, however, are effected by the reduced voltage differences between supply voltages and IO levels.For this reason some timings are adjusted to the new circumstances and the operation at 3 V is limited to a CPU clock frequency of up to 14 MHz for the standard temperature range (0...70°C) and up to 12 MHz for the temperature range -40...85°C.
