Pin details and its address range in 8085 Microprocessor
Let us assume that we have a RAM chip of 2K x 8, It signifies that, we have 2 x 1024 = 2048 memory locations having information of 8 bits at each location. For selecting one of 2K = 211 memory locations in chip, there should be exactly input pins of 11 address lines. For bidirectional data transfer scheme, there should be eight pin involved in this process. The processor action involved in it is signified by the input pins RD* and WR*. Two pins are specified for grounding process of the pin and connecting of Direct Current of +5 ...

You can use LIKE operator to find strings with a given prefix.The syntax is as followsselect *from yourTableName where yourColumnName LIKE 'yourPrefixValue%';To understand the above syntax, let us create a table. The query to create a table is as followsmysql> create table findStringWithGivenPrefixDemo -> ( -> UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> UserMessage text -> ); Query OK, 0 rows affected (0.82 sec)Insert some records in the table using insert command.The query is as followsmysql> insert into findStringWithGivenPrefixDemo(UserMessage) values('Hi Good Morning !!!'); Query OK, 1 row affected (0.17 sec) mysql> insert into findStringWithGivenPrefixDemo(UserMessage) values('Hey ...
Read MoreUse of 74138 in ALS-SDA-85M kit
In the ALS-SDA-85M kit, we have 74138 EPROM of minimum size 16K x 8 and size of RAM IS 2K x 8, there are empty sockets for the EPROM to get expanded. The selection of these four chips is done by the integrated circuit 74138. Every time the selection of 74138 is done when IO/M* turns to 0, the election of 27138 is done when A15A14 turns to 0. 27138 have the lowest address range likeLowest address: 00 00000000000000 is 0000H.Highest address: 00 11111111111111 is 3FFFH.Whereas in 74138 the address ranges are as follows -Lowest address: 11 xxx 00000000000Highest Address: 11 xxx 11111111111.The ...
