• Manufacturer: STMicroelectronics

1 - INTRODUCTION
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 on PQFP144 devices (or 5V to 2.7V on
TQFP144 devices). 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.

these two pins to 5.0V external supply.
Instead, these pins should be connected to a
