Oscillator Connections
Note:
When using the MCU Oscillator as a clock for an external device, an HC buffer should be
connected as indicated in the figure.

External Clock Drive Configuration
On-chip RC Oscillator
An On-chip RC Oscillator running at a fixed frequency of 1 MHz can be selected as the
MCU clock source. If enabled, the AT90S1200 can operate with no external compo-
nents. A control bit (RCEN) in the Flash Memory selects the On-chip RC Oscillator as
the clock source when programmed (
0
). The AT90S1200 is normally shipped with this
bit unprogrammed (
1
). Parts with this bit programmed can be ordered as
AT90S1200A. The RCEN-bit can be changed by parallel programming only. When
using the On-chip RC Oscillator for Serial Program downloading, the RCEN bit must be
programmed in Parallel Programming mode first.
