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 externalsupply. Instead, these pins should be connected to a decoupling capacitor (ceramic type, value330 nF).The A/D Converter characteristics are different from previous ST10 derivatives ones.
