CAT24C512
EEPROM Serial 512-Kb I
2
C
Description
The CAT24C512 is a EERPOM Serial 512Kb I
2
C internally
organized as 65,536 words of 8 bits each.
It features a 128byte page write buffer and supports the Standard
(100 kHz), Fast (400 kHz) and FastPlus (1 MHz) I
2
C protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
External address pins make it possible to address up to eight
CAT24C512 devices on the same bus.
OnChip ECC (Error Correction Code) makes the device suitable
for high reliability applications.

Table 1. ABSOLUTE MAXIMUM RATINGS
Parameters Ratings Units
Storage Temperature –65 to +150 °C
Voltage on any Pin with Respect to Ground (Note 1) –0.5 to +6.5 V
Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The DC input voltage on any pin should not be lower than 0.5 V or higher than V
CC
+ 0.5 V. During transitions, the voltage on any pin may
undershoot to no less than 1.5 V or overshoot to no more than V
CC
+ 1.5 V, for periods of less than 20 ns.

2. These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AECQ100
and JEDEC test methods.

CC
= 5 V, 25°C.
4. The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte
has to be written, 4 bytes (including the ECC bits) are re-programmed. It is recommended to write by multiple of 4 bytes in order to benefit
from the maximum number of write cycles.

pins are pulled down to GND internally. For improved noise immunity, the internal pulldown is relatively
strong; therefore the external driver must be able to supply the pulldown current when attempting to drive the input HIGH. To conserve power,
as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x V
CC
), the strong pulldown reverts to a weak current source.
