Study Notes
8051 Microcontroller Overview
- The 8051 microcontroller features 4 I/O ports, not 8.
- It operates on a Harvard architecture, allowing simultaneous access to program and data memory.
- Recognized as a microcontroller, the 8051 is widely utilized in embedded system applications.
ALE (Address Latch Enable) Functions
- ALE is indeed an output pin, used for latching the address from the data bus.
- It is not an input pin; rather, it signals when the address information is valid.
- The primary function of ALE is to assist in separating address and data lines to effectively manage memory access.
