HG24C04 数据手册

HG24C02/04/08/16

START CONDITION: A high-to-low transition of SDA with SCL high is a start condition whichmust precede any

other command (see to Figure 2 on page 5).

STOP CONDITION: A low-to-high transition of SDA with SCL high is a stop condition. After a read sequence,

the stop command will place the EEPROM in a standby power mode (see Figure 2 onpage 5).

ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROMin 8-bit

words. The EEPROM sends a "0" to acknowledge that it has received each word. This happens during the

ninth clock cycle.

STANDBY MODE: The HG24C02 / HG24C04 / HG24C08 / HG24C16 features a low-power standbymode

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 protocol, power loss or system reset, any two-wire partcan

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.
