PCF8598C-2 2 1024 8-bit CMOS EEPROM with I C-bus interface Rev. 06 22 October 2004 Product data 1. Description The PCF8598C-2 is a oating gate Electrically Erasable Programmable Read Only Memory (EEPROM) with 8 kbits (1024 8-bit) non-volatile storage. By using an internal redundant storage code, it is fault tolerant to single bit errors. This feature dramatically increases the reliability compared to conventional EEPROMs. Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier. 2 Data bytes are received and transmitted via the serial I C-bus. Up to two 2 PCF8598C-2 devices may be connected to the I C-bus. Chip select is accomplished by one address input (A2). Timing of the E/W cycle is carried out internally, thus no external components are required. Programming Time Control (PTC), Pin 7, must be connected to either V DD or left open-circuit. There is an option of using an external clock for timing the length of an E/W cycle. 2. Features Low power CMOS: 2.0 mA maximum operating current maximum standby current 10 A (at 6.0 V), typical 4 A Non-volatile storage of 8 kbits organized as 1024 8-bit Single supply with full operation down to 2.5 V On-chip voltage multiplier 2 Serial input/output I C-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) Internal power-on reset 0 kHz to 100 kHz clock frequency High reliability by using a redundant storage code Endurance: 1,000,000 Erase/Write (E/W) cycles at T =22 C amb 10 years non-volatile data retention timePCF8598C-2 Philips Semiconductors 2 1024 8-bit CMOS EEPROM with I C-bus interface ESD protection exceeds 2000 V HBM per JESD22-A114, 150 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101 Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA Offered in DIP8 and SO8 packages. 3.
