Product data
1. Description
The PCF85103C-2 is a 鏗俹ating gate Electrically Erasable Programmable Read Only
Memory (EEPROM) with 2 kbits (256
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 eight
PCF85103C-2 devices may be connected to the I
2
C-bus. Chip select is accomplished
by three address inputs (A0, A1 and A2).
The PCF85103C-2 is identical to PCF85102C-2 except for the 鏗亁ed I
2
C address,
allowing up to eight PCF85102C-2 and eight PCF85103C-2 on the same I
2
C-bus.
