AT24C02A/04A/08A/16A
5083A–SEEPR–9/04
The AT24C08A only uses the A2 input for hardwire addressing, and a total of two 8K
devices may be addressed on a single bus system. The A0 and A1 pins are no-
connects.
The AT24C16A does not use the device address pins, which limits the number of
devices on a single bus to one. The A0, A1, and A2 pins are no-connects.
WRITE PROTECT (WP):
The AT24C02A/04A/08A/16A have a WP pin that provides
hardware data protection. The WP pin allows normal read/write operations when con-
nected to ground (GND). When the WP pin is connected to V
CC
, the write protection
feature is enabled and operates as shown. (See Table 1.)
Table 1.
Write Protect
Memory Organization
AT24C02A, 2K SERIAL EEPROM:
The 2K is internally organized with 32 pages of 8
bytes each. Random word addressing requires an 8-bit data word address.
AT24C04A, 4K SERIAL EEPROM:
The 4K is internally organized with 32 pages of 16
bytes each. Random word addressing requires a 9-bit data word address.
AT24C08A, 8K SERIAL EEPROM:
The 8K is internally organized with 64 pages of 16
bytes each. Random word addressing requires a 10-bit data word address.
AT24C16A, 16K SERIAL EEPROM:
The 16K is internally organized with 128 pages of
16 bytes each. Random word addressing requires an 11-bit data word address.
Note:
This parameter is characterized and is not 100% tested.
