HN58V65A series, hn58v66a series 19 functional description automatic page write page-mode write feature allows 1 to 64 bytes of data to be written into the eeprom in a single write cycle. following the initial byte cycle, an additional 1 to 63 bytes can be written in the same manner. each additional byte load cycle must be started within 30 s from the preceding falling edge of :( or &( . when &( or :( is kept high for 100 s after data input, the eeprom enters write mode automatically and the input data are written into the eeprom. 'dwd 'dwd polling 'dwd polling indicates the status that the eeprom is in a write cycle or not. if eeprom is set to read mode during a write cycle, an inversion of the last byte of data outputs from i/o7 to indicate that the eeprom is performing a write operation. rdy/ %xv\ %xv\ signal rdy/ %xv\ signal also allows status of the eeprom to be determined. the rdy/ %xv\ signal has high impedance except in write cycle and is lowered to v ol after the first write signal. at the end of a write cycle, the rdy/ %xv\ signal changes state to high impedance. 5(6 5(6 signal (only the hn58v66a series) when 5(6 is low, the eeprom cannot be read or programmed. therefore, data can be protected by keeping 5(6 low when v cc is switched. 5(6 should be high during read and programming because it doesnt provide a latch function. v program inhibit cc res program inhibit read inhibit read inhibit

HN58V65A series, hn58v66a series 21 2. data protection at v cc on/off when v cc is turned on or off, noise on the control pins generated by external circuits (cpu, etc) may act as a trigger and turn the eeprom to program mode by mistake. to prevent this unintentional programming, the eeprom must be kept in an unprogrammable state while the cpu is in an unstable state. note: the eeprom shoud be kept in unprogrammable state during v cc on/off by using cpu reset signal. v cc cpu reset unprogrammable unprogrammable * * (1) protection by &( , 2( , :( to realize the unprogrammable state, the input level of control pins must be held as shown in the table below. &( v cc 2( v ss :( v cc : dont care. v cc : pull-up to v cc level. v ss : pull-down to v ss level.
HN58V65A series, hn58v66a series 22 (2) protection by 5(6 (only the hn58v66a series) the unprogrammable state can be realized by that the cpus reset signal inputs directly to the eeproms 5(6 pin. 5(6 should be kept v ss level during v cc on/off. the eeprom breaks off programming operation when 5(6 becomes low, programming operation doesnt finish correctly in case that 5(6 falls low during programming operation. 5(6 should be kept high for 10 ms after the last data input. v cc res we or ce 100 s min 10 ms min 1 s min program inhibit program inhibit
HN58V65A series, hn58v66a series 23 3. software data protection to prevent unintentional programming caused by noise generated by external circuits, this device has the software data protection function. in software data protection mode, 3 bytes of data must be input before write data as follows. and these bytes can switch the non-protection mode to the protection mode. sdp is enabled if only the 3 bytes code is input. data aa 55 a0 write data } address 1555 0aaa 1555 write address normal data input software data protection mode can be cancelled by inputting the following 6 bytes. after that, this device turns to the non-protection mode and can write data normally. but when the data is input in the cancelling cycle, the data cannot be written. data aa 55 80 aa 55 20 address 1555 0aaa 1555 1555 0aaa 1555 the software data protection is not enabled at the shipment. note: there are some differences between hitachis and other companys for enable/disable sequence of software data protection. if there are any questions , please contact with hitachi sales offices.
