Description

The PCF85116-3 is an 16 kbits (2048 × 8-bit) floating gate Electrically Erasable Programmable Read Only Memory (EEPROM). By using redundant EEPROM cells it is fault tolerant to single bit errors. In most cases multi bit errors are also covered. This feature dramatically increases reliability compared to conventional EEPROM memories. Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier.
