ST10F269
1 - INTRODUCTION
The ST10F269 is a derivative of the
STMicroelectronics ST10 family of 16-bit
single-chip CMOS microcontrollers. It combines
high CPU performance (up to 20 million
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 0.35µm 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
standard. This MAC unit adds powerful DSP
functions to the ST10 architecture, but maintains
full compatibility for existing code.
– Flash control interface is now based on
STMicroelectronics third generation of
stand-alone Flash memories, with an embedded
Erase/Program Controller. This completely

frees up the CPU during programming or
erasing the Flash.
– Two dedicated pins (DC1 and DC2) on the
PQFP-144 package are used for decoupling the
internally generated 3.3V core logic supply. Do
not connect these two pins to 5.0V external
supply. Instead, these pins should be
connected to a decoupling capacitor (ceramic
type, value 330 nF).
– The A/D Converter characteristics are different
from previous ST10 derivatives ones. Refer to
Section 21.3.1 - A/D Converter Characteristics.
– The AC and DC parameters are adapted to the
40MHz maximum CPU frequency. The
characterization is performed with CL = 50pF
max on output pins. Refer to Section 21.3 DC
Characteristics.
– In order to reduce EMC, the rise/fall time and the
sink/source capability of the drivers of the I/O
pads are programmable. Refer to Section 12.2 I/
O’s Special Features.
– The Real Time Clock functionnality is added.
– The external interrupt sources can be selected
with the EXISEL register.
– The reset source is identified by a dedicated
status bit in the WDTCON register.
