Z86C44中文资料ZILOG数据手册PDF规格书

GENERAL DESCRIPTION

ZiLOG’s Z8® MCU single-chip family now includes the Z86C34/C35/C36/C44/C45/C46 product line, featuring enhanced wake-up circuitry, programmable Watch-Dog Timers (WDT), and low-noise/EMI options. Each of the new enhancements to the Z8 offer a more efficient, cost-effective design and provide the user with increased design flexibility over the standard Z8 microcontroller core. The low-power consumption CMOS microcontroller offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion.
