M34C00MN Datasheet

M34C00MN 3 x 128 bit Serial IC Bus EEPROM For ee-Tags

The M34C00 is a 384-bit serial EEPROM. The bottom third of the memory area (from location 00h to 0Fh) can be Write-protected using a specially designed software Write-protection mechanism. By sending the device a specific sequence, the first 128 bits of the memory become permanently Write-protected..

Features

configured to give the functional equivalence of a non-erasable memory. That is, it is initialized to all 1s (FFh), and the user is able to reset any number of those 1s to 0; but there is no mechanism for the user to set a 0 back to a 1. The M34C00 is a 384-bit electrically erasable programmable memory (EEPROM), organized as 48 x 8 bits. Figure 1. Logic Diagram VCC SCL M34C00 SDA Table 1.
