AiT Semiconductor Inc. www.ait-ic.com A24C64 MEMORY EEPROM 64k BITS (8192 X 8) TWO -WIRE SERIAL REV2.1 - SEP 2008 RELEASED, JUN 2019 UPDATED - - 6 - DETAILED INFORMATION DEVICE/PAGE ADDRESSES (A2, A1 and A0): The A2, A1 and A0 pins are device address inputs that are hard wire for the A24C64. Eight 64k devices may be addressed on a single bus system (device addressing is discussed in detail under the Device Addressing section). SERIAL DATA (SDA): The SDA pin is bi-directional 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. SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. WRITE PROTECT (WP): The A24C64 has a Write Protect pin that provides hardware data protection . The Write Protect pin allows normal read/write operations when connected to ground (GN D). When the Write protection pin is connected to V CC, the write protection feature is enabled and operates as shown in the following Table 1. Table1.

AiT Semiconductor Inc. www.ait-ic.com A24C64 MEMORY EEPROM 64k BITS (8192 X 8) TWO -WIRE SERIAL REV2.1 - SEP 2008 RELEASED, JUN 2019 UPDATED - - 8 - ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROM in 8 -bit words. The EEPROM sends a “0” to acknowledge that it has received each word. This happens during the ninth clock cycle. Figure 3 Output Acknowledge STANDBY MODE : The A24C64 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. MEMORY RESET : After an interruption in prot ocol, power loss or system reset, any two -wire part can be reset by following these steps: 1. Clock up to 9 cycles. 2. Look for SDA high in each cycle while SCL is high. 3. Create a start condition.

The Identification Page can be read by issuing a Read Identification Page instruction. This instruction uses the same protocol and format as the Random Address Read (from memory array) with device type identifier defined as 1011b. The MSB address bits B15/B6 are don't care, the LSB address bits B5/B0 define the byte address inside the Identification Page. The number of b ytes to read in the ID page must not exceed the page boundary (e.g.: when reading the Identification Page from location 10d, the number of bytes should be less than or equal to 22, as the ID page boundary is 32 bytes) LOCK IDENTIFUCATION PAGE: The Lock Id entification Page instruction (Lock ID) permanently locks the Identification page in Read -only mode. The Lock ID instruction is similar to Byte Write (into memory array) with the following specific conditions: Device type identifier = 1011b Address bit B10 must be '1'; all other address bits are don't care The data byte must be equal to the binary value xxxx xx1x, where x is don't care
