The STA instruction in the 8085 has 13 T states, 4 for opcode fetch, 3 for low half immediate address fetch, 3 for high half immediate address fetch, and 3 for data write.

Difference between LDA and STA instruction in 8085?

In the 8085, the LDA instruction loads the accumulator from memory, while the STA instruction stores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.

What is STA in 8085?

STA is used to store the content of the accumulator in to the specified memory address. for example STA 4200. it stores the content of accumulator at 4200.

How many machine cycles and T-series requires to complete the execute STA 4200H in 8085 microprocessor?

The STA 4200H instruction in the 8085 requires 4 machine cycles and 13 T states to complete its fetch, processing, and execution. Cycle One: Opcode fetch, 3 T states plus one opcode process state. Cycle Two: Opcode address byte 00H fetch, 3 T states Cycle Three: Opcode address byte 42H fetch, 3 T states Cycle Four: Accumulator store, 3 T states. Each cycle will have additional T-Ready states as needed by the READY pin. 13 T states is the minimum. The LDA instruction will also require 13 T states, with the last cycle being a read cycle instead of a write cycle.
