ST10F280
1 - INTRODUCTION
The ST10F280 is a new derivative of the ST
Microelectronics 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.
ST10F280 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
ST10F269 device, with the following set of
differences:
– Two supply pins (DC1,DC2) on the PBGA-208
package are used for decoupling the internally
generated 3.3V core logic supply. Do not con-
nect these two pins to 5.0V external supply. In-
stead, these pins should be connected to a

decoupling capacitor (ceramic type, value
≥ 330nF).
– The A/D Converter characteristics stay identical
but 16 new input channel are added. A bit in a
new register (XADCMUX) control the multiplex-
age between the first block of 16 channel (on
Port5) and the second block (on XPort10). The
conversion result registers stay identical and the
software management can determine the block
in use. A new dedicated timer controls now the
ADC channel injection mode on the input CC31
(P7.7). The output of this timer is visible on a
dedicated pin (XADCINJ) to emulate this new
functionnality.
– A second XPWM peripheral (4 new channels) is
added. Four dedicated pins are reserved for the
outputs (XPWM[0:3])
– A new general purpose I/O port named XPORT9
(16 bits) is added. Due to the bit addressing
management, it will be different from other
standard general purpose I/O ports.
