British Ale Beer Pin Stock Image Image Of Public Beer 83341489 The ale (address latch enable) pin is an output in the 8085 microprocessor. it has to generate a pulse when the microprocessor intends to latch the lower 8 bits of the memory address. physically, the ale pin connects externally with latch circuits that in turn capture the address applied to the address bus. 15k views. ale pin in 8085 microprocessor intel 8085 is an 8 bit microprocessor which has 16 address line for 16 bit address of a memory location. 8 higher order address bits are transferred through 8 bit lines out of this 16 address line while remaining lower order 8 bits of the address are sent through another 8 lines multiplexed with the.
Pin On Ale This pin of the 8085 microprocessor, ale, is one of the most important pins used in interfacing with external memory devices. during any machine cycle, while interfacing with an external memory using the 8085 microprocessor, the ale pin latches the lower order address bits, a0 a7. during the beginning of each machine cycle, the microprocessor outpu. Ale – ale is an acronym for address latch enable and is pin number 30 in the configuration. we know that 8 lower order bits of the 16 bit address bus are multiplexed with the 8 bit data bus. this pin gets enabled at the time when the address is present at the multiplexed address and data bus. Ale some ic's overlap address bus and data bus pins to minimize the number of pins needed. that means one pin can be used as an address pin or as a data pin depending on the current state of the bus. for the logic to work properly address value should be present for the whole read or write operation. 8085 pin diagram address and data bus (pins ad0 ad7 and pins a8 a15) ad0 ad7 (lower order address data bus) these pins are multiplexed. that means that they perform dual tasks. the address bus is used to connect with io devices or memory. the 8085 has another pin, which helps in demultiplexing these 8 pins. that is the ale pin.
