AT24C04B-TH-B Atmel, AT24C04B-TH-B Datasheet

Page 1

... The AT24C04B/08B is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra-Thin Mini- MAP (MLP 2x3), 5-lead SOT23, 8-lead TSSOP, and 8-ball dBGA2 packages and is accessed via a Two-wire serial interface. In addition, the AT24C04B/08B is available in 1.8V (1.8V to 5.5V) version. Figure 1. Pin Configurations ...

... SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is open drain driven and may be wire-ORed with any number of other open-drain or open-collector devices. DEVICE/PAGE ADDRESSES (A2, A1, A0): The AT24C04B uses the A2 and A1 inputs for hard wire addressing and a toal of four 4K devices may be addressed on a single bus system. The A0 pin connect and can be connected to ground (device addressing is discussed in detail under the Device Addressing section) ...

... ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle. STANDBY MODE: The AT24C04B/08B features a low-power standby mode which is enabled: (a) Upon power-up and (b) After the receipt of the STOP bit and the completion of any internal operations ...

... The device address word consists of a mandatory one, zero sequence for the first four most significant bits as shown. This is common to all the EEPROM devices. The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a memory page address bit. The two device address bits must compare to their corresponding hard-wired input pins. The A0 pin is no connect. ...
