タイトルまたは説明

MM23SC4428 or popularly known as 4428 module is a secured memory chip DESIGNED in Malaysia by Malaysia Microelectronic Solutions Sdn Bhd (My-MS). It is widely used in various applications for identification, access control and loyalty cards. We have shipped millions of these modules to various smart card manufacturers & end users worldwide.

 

 

 

Our MM23SC4428 is reliable & robust under normal use and handling. We are able to ship our products within reasonable delivery lead time to meet customers expectation. As the product owner, we can customize the manufacturers byte code / special header based on customers requirement. We offer high quality products at competitive prices.

 

 

 

MM23SC4428 contains 1024 x 8 bits of EEPROM with programmable write protection for each byte. Each byte in the memory has a corresponding protect bit.  The protect bits are only one time programmable and cannot be erased. After the protect bits are enabled (logic 0), the corresponding bytes can never be changed again. A write-protect bit with data-compare function is available for user to verify the data in the memory before enabling the protect bit.

 

 

 

MM23SC4428 also offers two bytes of Programmable Security Code (PSC) against unauthorized memory write/erase operations. All the memory, except for the PSC can always be read, but the memory can be written or erased only after PSC verification. If the user fails to enter the correct PSC in eight consecutive attempts, the device will block any further PSC entry attempts and the memory can never be erased or written again.
