ST10F269Z2Q6 Description
The ST10F269Z1-ST10F269Z2 are derivatives 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/Ocapabilities. It also provides on-chip high-speed single voltage Flash memory, on-chip highspeed RAM, and clock generation via PLL.
The ST10F269Z1-ST10F269Z2 are processed in 0.35 mm CMOS technology. The MCU core and the logic is supplied with a 5 V to 2.7 V on chip voltage regulator. The part is supplied with a single 5 V supply and I/Os work at 5 V.
