Serial EEPROM

Description:

The Microchip Technology Inc. 24AA024/24LC024/

24AA025/24LC025 is a 2 Kbit Serial Electrically

Erasable PROM with a voltage range of 1.7V to 5.5V.

The device is organized as a single block of 256 x 8-bit

memory with a 2-wire serial interface. Low current

design permits operation with typical standby and

active currents of only 1 μA and 1 mA, respectively.

The device has a page write capability for up to 16

bytes of data. Functional address lines allow the

connection of up to eight 24AA024/24LC024/

24AA025/24LC025 devices on the same bus for up to

16K bits of contiguous EEPROM memory. The device

is available in the standard 8-pin PDIP, 8-pin SOIC

(3.90 mm), TSSOP, 2x3 DFN and TDFN and MSOP

packages. The 24AA025/24LC025 is also available in

the 6-lead SOT-23 package.

... Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24AA024/ 24LC024/24AA025/24LC025 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated. ...

... The master device must generate an extra clock pulse, which is associated with this Acknowledge bit. Note: The 24AA024/24LC024/24AA025/24LC025 does not generate any Acknowledge bits if an internal programming cycle is in prog- ress. The device that acknowledges has to pull down the SDA ...

... The Chip Select bits A2, A1 and A0 can be used to expand the contiguous address space for up to 16K bits by adding up to eight 24AA024/24LC024/24AA025/ 24LC025 devices on the same bus. In this case, soft- ware can use A0 of the control byte as address bit A8 address bit A9 and A2 as address bit A10 not possible to sequentially read across device boundaries ...

... Page Write The write control byte, word address and the first data byte are transmitted to the 24AA024/24LC024/ 24AA025/24LC025 in the same way byte write. However, instead of generating a Stop condition, the master transmits additional data bytes to the 24AA024/24LC024/24AA025/24LC025, temporarily stored in the on-chip page buffer and will be written into the memory once the master has transmit- ted a Stop condition ...

Page 9

... ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a Write command has been issued from the master, the device initiates the internally-timed write cycle, with ACK polling being initiated immediately ...
