4 / 38 page ![]() 4 Rev. 6.1/May 01 HY29F080 CONVENTIONS Unless otherwise noted, a positive logic (active High) convention is assumed throughout this docu- ment, whereby the presence at a pin of a higher, more positive voltage (nominally 5VDC) causes assertion of the signal. A ‘#’ symbol following the signal name, e.g., RESET#, indicates that the sig- nal is asserted in a Low state (nominally 0 volts). Whenever a signal is separated into numbered bits, e.g., DQ[7], DQ[6], ..., DQ[0], the family of bits may also be shown collectively, e.g., as DQ[7:0]. The designation 0xNNNN (N = 0, 1, 2, . . . , 9, A, . . . , E, F) indicates a number expressed in hexa- decimal notation. The designation 0bXXXX indi- cates a number expressed in binary notation (X = 0, 1). e m a N e p y T n o i t p i r c s e D ] 0 : 9 1 [ As t u p n I . h g i H e v i t c a , s s e r d d A s e t y b ) M 1 ( 6 7 5 , 8 4 0 , 1 f o e n o t c e l e s s t u p n i y t n e w t e s e h T e h t s i ] 0 [ A d n a B S M e h t s i ] 9 1 [ A . s n o i t a r e p o e t i r w r o d a e r r o f y a r r a e h t n i h t i w .

A sector is the smallest unit that can be erased. Adjacent pairs of sectors (S0/S1, S2/S3, . . . , S14/S15) are designated as a sector group. A sector group is the smallest unit which can be protected to prevent accidental or unauthorized erasure. See ‘Bus Operations’ and ‘Command Definitions’ sections of this document for additional information on these functions. Table 1 defines the sector addresses, sector group addresses and corresponding address ranges for the HY29F080. |
