16位MCU MAC单元， 512K字节Flash存储器和18K字节的RAM 16-BIT MCU WITH MAC UNIT, 512K BYTE FLASH MEMORY AND 18K BYTE RAM
INTRODUCTION
The is a new derivative of the 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.
