3 / 20 page 2000 Feb 15 3 Philips Semiconductors Product specification 256 × 8-bit CMOS EEPROMs with I2C-bus interface PCF85102C-2; PCF85103C-2 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. 3 QUICK REFERENCE DATA SYMBOL PARAMETER CONDITIONS MIN. MAX. UNIT VDD supply voltage 2.5 6.0 V IDDR supply current read fSCL = 100 kHz VDD = 2.5 V − 60 µA VDD = 6.0 V − 200 µA IDDW supply current E/W fSCL = 100 kHz VDD = 2.5 V − 0.6 mA VDD = 6.0 V − 2.0 mA IDDstb standby supply current VDD = 2.5 V − 3.5 µA VDD = 6.0 V − 10 µA |
