2-Wire Serial 4K-Bit (512 x 8) CMOS Electrically Erasable PROM
AM24LC04
ꢀ Features
ꢀ General Description
• State- of- the- art architecture
- Non-volatile data storage
The AM24LC04 is a non-volatile, 4096-bit serial
EEPROM with conforms to all specifications in I2C 2
wire protocol. The whole memory can be disabled
(Write Protected) by connecting the WP pin to Vcc.
This section of memory then becomes unalterable
unless WP is switched to Vss. The AM24LC04
communication protocol uses CLOCK(SCL) and
DATA I/O(SDA) lines to synchronously clock data
- Standard voltage and low voltage operation
(Vcc = 2.7V to 5.5V) for AM24LC04
• 2-wire I2C serial interface
- Provides bi-directional data transfer protocol
• 16-byte page write mode
- Minimizes total write time per word
• Self-timed write-cycle (including auto-erase)
• Durable and Reliable
between

master
the
(for
slave
example

microcomputer)and
EEPROM
- 40 years data retention
devices(s) .In addition, the bus structure allows for a
maximum of 16K of EEPROM memory. This
supports the family in 2K, 4K, 8K devices, allowing
the user to configure the memory as the application
requires with any combination of EEPROMs (not to
exceed 16K).
- Minimum of 1M write/erase cycles per word
- Unlimited read cycles
- ESD protection
• Low standby current
• Packages: PDIP-8L, SOP-8L, TSSOP-8L
Anachip EEPROMs are designed and tested for
application requiring high endurance, high reliability,
and low power consumption.
