256 × 8-bit CMOS EEPROMs with
PCF85102C-2; PCF85103C-2
I2C-bus interface
1 FEATURES
∙Low power CMOS:
–maximum operating current: 2.0 mA
–maximum standby current 10 μA (at 6.0 V), typical 4 μA.
∙Non-volatile storage of:
–2 kbits organized as 256 × 8-bit.
∙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: 1000000 Erase/Write (E/W) cycles at Tamb = 22 °C
∙10 years non-volatile data retention time
∙Standard industrial pinning (pin 7 not connected)
∙Up to sixteen EEPROMs addressable in one I2C-bus using both PCF85102 and PCF85103 in combination.
2 GENERAL DESCRIPTION
The PCF85102C-2 and PCF85103C-2 (further referred to as PCF8510xC-2) are 2 kbits (256 × 8-bit) floating gate Electrically Erasable Programmable Read Only Memories (EEPROMs). Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier.
The PCF8510x-2 is pin compatible to widely used industrial pinning (pin 7 not connected).
As data bytes are received and transmitted via the serial I2C-bus, a package using eight pins is sufficient. Up to sixteen PCF8510xC-2 devices may be connected to the I2C-bus. This is possible with the introduction of a second device selection code. Chip select is accomplished by three address inputs (A0, A1 and A2) for each PCF8510xC-2 type.
