This function takes three arguments, the device address the disk1 variable , the memory address on the eeprom and the byte of data you want to write. The first argument is the address of the device you want to write to, in our case we only have one device disk1 so we pass this on. The next argument is the address on the eeprom you want to write to and as stated above can be between 0 and 32, Finally we have to pass along the byte we want to store.

Part Number Start With

Next we have to send the address on the eeprom we want to write to. Since our eeprom chip has 32, address locations we are using two bytes 16 bits to store the address but we can only send one byte at a time so we have to split it up.

The first send function takes the eeaddress and shifts the bits to the right by eight which moves the higher end of the 16 bit address down to the lower eight bits.

Next we do a bitwise AND to get just the last eight bits.


To illustrate this lets follow the steps below. Lets say we want to write to address location 20, which is in binary.

As with the byte write operation, all inputs are disabled until completion of the internal write cycle. Refer to Figure 6 for the address, acknowledge and data transfer sequence.

These are the word addresses and comprise fifteen bits to provide access to any one of the 32K words. The first byte indicates the high-order byte of the word address. Only the seven least signicant bits can be changed, the most significant bit is pre-assigned the value "0". Following the acknowledgement from the first word address, the next byte indicates the low-order byte of the word address.

Upon receipt of the word address, the FM24Cxxx responds with another acknowledge and waits for the next eight bits of data, again, responding with an acknowledge. Salah satu software berbayar, dikenal dengan nama ChA Mini Programer, yang dibuat oleh seseorang dengan nickname SkyGz.

Software ini nampaknya menjadi pavorit para pengguna tool CHA.

Sehingga banyak situs atau forum diskusi yang membicarakan tentang software ini. Jika anda mencari software ini via search engine google , harap berhati-hati.

Hampir semua aplikasi ChA Mini Programer yang linknya bertebaran didunia maya, mengandung virus.

Sekali lagi, sebaiknya berhati-hati. Gunakan antivirus yang bagus, agar anda terhindar dari jebakan yang beresiko. Jika anda berminat untuk memperoleh ChA Mini Programer secara legal, silahkan hubungi pada developernya dengan alamat email: SkyGZ qq.

Juga tersedia driver untuk Linux, Mac dan Android. Langkah instalasi driver dilakukan sebagai berikut : Karena sangat penting, sekali lagi kami mengingatkan anda.

Jika tidak mendownload situs developernya. Downloadlah disitus penjual yang memiliki reputasi atau yang anda percayai.

Kami banyak menerima informasi bahwa driver yang diunduh ternyata mengandung virus berbahaya, yang diam-diam ikut menyelinap ke dalam sistem komputer.This is because it's very slow — or impossible — to write new data to ROM.

Because this is how the device expects to receive them, that's all. Time to move on to software!

We need to send the MSB Most significant bits first so we have to shift our address to the right eight bits. You could just ground them all, but we'll be wiring them so that we can drop in a higher-capacity device later in the tutorial.

Reading and Writing Serial EEPROMs

Time to move on to software! When you press "Open" you'll see a file transfer window for just a moment as the file is dumped to the terminal. Once we've transferred bytes, we've got everything on the chip.

This was memory made up of discrete semiconductor diodes placed on a specially organized PCB.
