ST10F166
1 INTRODUCTION
The ST10F166 is the FLASH memory members of the ST10 family of microcontrol-
lers developed and produced by SGS-THOMSON Microelectronics in CMOS tech-
nology. they combine high CPU performance (up to 10 million instructions per sec-
ond) with high peripheral functionality, enhanced IO-capabilities and an on-chip re-
programmable 32 KByte Flash Memory.
The ST10F166-16 derives its CPU clock signal (operating clock) directly from the on-
chip oscillator without using a prescaler.
With a clock duty cycle of 0.4 to 0.6, the recommended clock frequency is 16MHz for
the ST10F166.
The ST10F166 operates at half the oscillator clock frequency (using a 2:1 oscillator
prescaler).
