ST10F269
1 - INTRODUCTION
The
STMicroelectronics
single-chip CMOS microcontrollers. It combines
high
instructions per second) with high peripheral
functionality and enhanced I/O-capabilities. It also
provides on-chip high-speed single voltage Flash
memory, on-chip high-speed RAM, and clock
generation via PLL.
ST10F269 is processed in 0.35 m CMOS
technology. The MCU core and the logic is
supplied with a 5V to 3.3V on chip voltage
regulator. The part is supplied with a single 5V
supply and I/Os work at 5V.
The device is upward compatible with the
ST10F168 device, with the following set of
differences:
– The Multiply/Accumulate unit is available as
– Flash control interface is now based on

standard. This MAC unit adds powerful DSP
functions to the ST10 architecture, but maintains
full compatibility for existing code.
