V29LC51000 Rev. 0.4 October 2000 7 MOSEL VITELIC V29LC51000 FUNCTIONAL DESCRIPTION V29LC51001 Read Cycle 512 A read cycle is performed by holding both CE and OE signals LOW. Data Out becomes valid only when these conditions are met. During a read cycle WE must be HIGH prior to CE and OE going LOW. WE must remain HIGH during the read operation for the read to complete (see Table 1). 512 • • • 512 Output Disable 512 Returning OE or CE HIGH, whichever occurs first will terminate the read operation and place the l/O pins in the HIGH-Z state. 00000H L51001-13 During the byte program cycle, addresses are latched on the falling edge of either CE or WE, whichever is last. Data is latched on the rising edge of CE or WE, whichever is first. The byte program cycle can be CE controlled or WE controlled. Standby The device will enter standby mode when the CE signal is HIGH. The l/O pins are placed in the HIGH-Z, independent of the OE signal. Command Sequence Sector Erase Cycle The V29LC51000 does not provide the “reset” feature to return the chip to its normal state when an incomplete command sequence or an interruption has happened. In this case, normal operation (Read Mode) can be restored by issuing a “non-existent” command sequence, for example Address: 5555H, Data FFH. The V29LC51000 features a sector erase operation which allows each sector to be erased and reprogrammed without affecting data stored in other sectors. Sector erase operation is initiated by using a specific six-bus-cycle sequence: Two unlock program cycles, a setup command, two additional unlock program cycles, and the sector erase command (see Table 2). A sector must be first erased before it can be reprogrammed. While in the internal erase mode, the device ignores any program attempt into the device. Sector erase is completed in 10ms max. The V29LC51000 is shipped with pre-erased sectors (all bits = 1). Byte Program Cycle The V29LC51000 is programmed on a byte-bybyte basis. The byte program operation is initiated by using a specific four-bus-cycle sequence: two unlock program cycles, a program setup command and program data program cycles (see Table 2). Table 1.

The V29LC51000 features a chip-erase operation. The chip erase operation is initiated by using a specific six-bus-cycle sequence: two unlock program cycles, a setup command, two additional unlock program cycles, and the chip erase command (see Table 2). The chip erase operation is performed sequentially, one sector at a time. When the automated on chip erase algorithm is requested with the chip erase command sequence, the device automatically programs and verifies the entire memory array for an all zero pattern prior to erasure V29LC51000 Rev. 0.4 October 2000 Hardware Data Protection VCC Sense Protection: the program operation is inhibited when VCC is less than 2.5V. Noise Protection: a CE or WE pulse of less than 5ns will not initiate a program cycle. Program Inhibit Protection: holding any one of OE LOW, CE HIGH or WE HIGH inhibits a program cycle. 9 MOSEL VITELIC V29LC51000 Byte Program Algorithm Chip/Sector Erase Algorithm Write Program Command Sequence Write Erase Command Sequence Add/Data 5555H/AAH Add/Data 5555H/AAH 2AAAH/55H 2AAAH/55H Four Bus Cycle Sequence 5555H/A0H 5555H/80H Six Bus Cycle Sequence PA/PD 5555H/AAH Time Out 30µS 2AAAH/55H Byte Programming Complete 5555H/10H (Chip Erase) PA/30H (Sector Erase Time Out for Sector or Chip Erase Erase Complete L51000-14 V29LC51000 Rev. 0.4 October 2000 10 MOSEL VITELIC V29LC51000 Package Diagrams 32-pin Plastic DIP 1.660 MAX. 15° MAX INDEX-1 EJECTOR MARK .600 TYP 0.545/0.555 INDEX-2 +.004 .010 – .0004 .050 MAX 0.210 MAX 0.120 MIN .100 TYP +.006 .018 – .002 +.012 .047 – 0 0.010 MIN .032 +.012 –0 32-pin PLCC 20 19 18 17 16 15 14 21 13 22 12 23 11 24 10 25 9 26 8 27 7 28 .590 ± .005 .550 ± .003 6 29 30 31 32 1 2 3 4 5 .045X45° .450 ± .003 .110 .490 ± .005 .136 ± .003 .046 ± .003 .025 .050 TYP 30° .017 .420 ± .003 V29LC51000 Rev. 0.4 October 2000 3° - 6° 3° - 6° 11 3° - 6° MOSEL VITELIC WORLDWIDE OFFICES V29LC51000 U.S.A.
