Product data
1. Description
The PCF8598C-2 is a 鏗俹ating gate Electrically Erasable Programmable Read Only
Memory (EEPROM) with 8 kbits (1024
脳
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.
Data bytes are received and transmitted via the serial I
2
C-bus. Up to two
PCF8598C-2 devices may be connected to the I
2
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.
