Refer to command program mode in mode selection about operation mode. 2. Refer to device identifier mode. IA = Identifier address, PA = Programming address, EA = Erase verify address, RA = Read address 3. Refer to device identifier mode. PA are latched by programming command. ID = Identifier output code, PD = Programming data, PVD = Programming verify output data, EVD = Erase verify output data 4. Command latch default value when applying 12 V to VPP is “00H”. Device is in read mode after VPP is set 12 V (before other command is input). 5. All data in chip are erased. Erase data according to fast high-reliability erase flowchart. 6. All data in chip are erased. Data are erased automatically by internal logic circuit. External erase verify is not required. Erasure completion must be verified by status polling after automatic erase starts. 7. Program data according to fast high-reliability programming flowchart. 6 HN28F101 Series HN28F101 Series |
