4 / 40 page 4 Rev. 1.1/Feb 02 HY29F800A SIGNAL DESCRIPTIONS MEMORY ARRAY ORGANIZATION The 1 Mbyte Flash memory array is organized into nineteen blocks called sectors (S0, S1, . . . , S18). A sector is the smallest unit that can be erased and which can be protected to prevent accidental or unauthorized erasure. See the ‘Bus Operations’ and ‘Command Definitions’ sections of this docu- ment for additional information on these functions. In the HY29F800A, four of the sectors, which com- prise the boot block, vary in size from 8 to 32 Kbytes (4 to 16 Kwords), while the remaining fif- teen sectors are uniformly sized at 64 Kbytes (32 Kwords). The boot block can be located at the bottom of the address range (HY29F800AB) or at the top of the address range (HY29F800AT). Table 1 defines the sector addresses and corre- sponding address ranges for the top and bottom boot block versions of the HY29F800A. e m a N e p y T n o i t p i r c s e D ] 0 : 8 1 [ As t u p n I . h g i H e v i t c a , s s e r d d A 8 8 2 , 4 2 5 f o e n o t c e l e s s t u p n i 9 1 e s e h t , e d o m d r o w n I e s e h t , e d o m e t y b n I . 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 s d r o w ) K 2 1 5 ( 6 7 5 , 8 4 0 , 1 f o e n o t c e l e s o t ) B S L ( t u p n i ] 1 - [ A / ] 5 1 [ Q D e h t h t i w d e n i b m o c e r a s t u p n i . 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 s e t y b ) M 1 ( , ] 1 - [ A / ] 5 1 [ Q D ] 0 : 4 1 [ Q D s t u p t u O / s t u p n I e t a t s - i r T h g i H e v i t c a , s u B a t a D h t a p a t a d t i b - 6 1 a e d i v o r p s n i p e s e h t , e d o m d r o w n I . h t a p a t a d t i b - 8 n a e d i v o r p ] 0 : 7 [ Q D , e d o m e t y b n I . s n o i t a r e p o e t i r w d n a d a e r r o f ] 8 : 4 1 [ Q D . t u p n i s s e r d d a e t y b t i b - 0 2 e h t f o B S L e h t s a d e s u s i ] 1 - [ A / ] 5 1 [ Q D d n a . e d o m e t y b n i d e t a t s - i r t n i a m e r d n a d e s u n u e r a # E T Y Bt u p n I . w o L e v i t c a , e d o M e t y B . e c i v e d e h t f o n o i t a r u g i f n o c d r o W / e t y B e h t s l o r t n o C . e d o m d r o w s t c e l e s h g i H , e d o m e t y b s t c e l e s w o L # E Ct u p n I . w o L e v i t c a , e l b a n E p i h C r o m o r f a t a d d a e r o t d e t r e s s a e b t s u m t u p n i s i h T e h t d n a d e t a t s - i r t s i s u b a t a d e h t , h g i H n e h W .
