DESCRIPTION
The PCX8582X-2 is a 2-Kbit (256×8-bit) floating gate electrically erasable programmable read only memory
(EEPROM). By using an internal redundant storage code it is fault tolerant to single bit errors. This feature
dramatically increases reliability compared to conventional EEPROM memories.

FEATURES
• Low power CMOS
– maximum active current 2.0 mA
– maximum standby current 10µA (at 6.0 V), typical 4 µA
• Non-volatile storage of 2-Kbits organized as 256×8-bits
• Single supply with full operation down to 2.5 V
• On-chip voltage multiplier
• Serial input/output I2C-bus
• Write operations
– byte write mode
– 8-byte page write mode (minimizes total write time per byte)
• Read operations
– sequential read
– random read
• Internal timer for writing (no external components)
• Power-on reset
• High reliability by using a redundant storage code
• Endurance
– >500 k E/W-cycles at Tamb= 22°C
• 40 years non-volatile data retention time (typ.)
• Pin and address compatible to
– PCX8570, PCF8571, PCF8572 and PCF8581
– PCX8494X-2, PCX8598X-2 -Family.
