ST10F276Z5 Product Details

The ST10F276Z5 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS microcontrollers. It combines high CPU performance (up to 32 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.

The ST10F276Z5 is processed in 0.18 μm CMOS technology. The MCU core and the logic is supplied with a 5 to 1.8 V on-chip voltage regulator. The part is supplied with a single 5 V supply and I/Os work at 5 V.
The device is upward compatible with the ST10F269 device, with some differences.
