ST10F272B：16-bit MCU with 256 Kbyte Flash memory and 12 Kbyte RAM

The ST10F272B / E 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.

The ST10F272B / E is processed in 0.18 mm CMOS technology. The part is supplied with a single 5 V supply and I/Os work at 5 V.
