About N76E003AT20 Microcontroller
The N76E003 is an 8-bit microcontroller based on the 8051 architecture, with embedded flash memory and rich peripherals. It offers up to 18KBytes of main flash called APROM, which can be used for in-application programming and non-volatile data storage. The LDROM flash, with a maximum size of 4KBytes, is used for the boot code. The microcontroller is equipped with 18 sources of interrupts with 4-level priority capability. The system clock can be switched on-the-fly via software and can be slowed down with a software clock divider for a balance between execution performance and power consumption. It has two power modes, Idle and Power-down, which can be software-selectable to reduce power consumption. Overall, the N76E003 is well-suited for general-purpose, home appliance, or motor control system design.
