The PCF85xxC-2 is a family of floating gate Electrically
Erasable Programmable Read Only Memories
(EEPROMs) with 2, 4 and 8 kbits (256, 512 and
1024
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.
As data bytes are received and transmitted via the serial
I
eight PCF85xxC-2 devices may be connected to the
I
inputs (A0, A1 and A2).
Timing of the E/W cycle is carried out internally, thus no
external components are required. Pin 7 (PTC) must be
connected to either V
option of using an external clock for timing the length of an
E/W cycle.
