ST10F269-T3
16位MCU MAC单元， 256K字节Flash存储器和12K字节的RAM 16-BIT MCU WITH MAC UNIT, 256K BYTE FLASH MEMORY AND 12K BYTE RAM
INTRODUCTION
The 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-T3 is processed in 0.35µm CMOS technology. The MCU core and the logic is supplied with a 5V to 2.7V on chip voltage regulator. The part is supplied with a single 5V supply and I/Os work at 5V.
