6 / 186 page  ST10F280 6/186 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 0.35 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 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.
