AT49BV6416(T)
Notes: 1. The DATA FORMAT in each bus cycle is as follows: I/O15 - I/O8 (Don’t Care); I/O7 - I/O0 (Hex). The ADDRESS FORMAT in
each bus cycle is as follows: A11 - A0 (Hex), A11 - A21 (Don’t Care).
2. Since A11 is a Don’t Care, AAA can be replaced with 2AA.
3. Either one of the Product ID Exit commands can be used.
4. SA = sector address. Any word address within a sector can be used to designate the sector address (see pages 14 - 17
for details).
5. Once a sector is in the Hardlock protection mode, it cannot be disabled unless the chip is reset or power cycled.
6. PA is the plane address (A21 - A20).
7. During the fourth bus cycle, the manufacturer code is read from address PA+00000H, the device code is read from address
PA+00001H, and the data in the protection register is read from addresses 000081H - 000088H. PA (A21 - A20) must spec-
ify the same plane address as specified in the third bus cycle.
8. The fast programming option enables the user to program two words in parallel only when V
PP
= 10V. The addresses, Addr0
and Addr1, of the two words, D
IN0
and D
IN1
, must only differ in address A0. This command should be used for manufacturing
purpose only.
9. If data bit D1 is “0”, block B is locked. If data bit D1 is “1”, block B can be reprogrammed.
10. The default state (after power-up) of the configuration register is “00”.
11. Any address within the user programmable register region. Please see “Protection Register Addressing Table” on page 13.
12. For the AT49BV6416, xxxx = 0000H. For the AT49BV6416T, xxxx = 3F80H.
13. For the AT49BV6416, xxxx = 0000H. For the AT49BV6416T, xxxx = 0F80H.
