Description

The ST10F280 is a new 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.

ST10F280 is processed in 0.35

μm 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 connect these two pins to 5.0V

external supply. Instead, 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 multiplexage 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 functionality.

●

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.
