U505M EEPROM
The U505M is a 512-bit EEPROM internally organized as 32 × 16-bits. The programming volt-
age as well as the write-cycle timing is generated on-chip. The U505M features a serial interface
allowing operation on a simple two-wire bus with an MCL protocol. Its low power consumption
makes it well suited for battery applications.
