AM29BDD160G AMD [Advanced Micro Devices], AM29BDD160G Datasheet - Page 72

• Manufacturer Part Number: AM29BDD160G
• Description: 16 Megabit (1 M x 16-bit/512 K x 32-Bit), CMOS 2.5 Volt-only Burst Mode, Dual Boot, Simultaneous Read/Write Flash Memory
• Manufacturer: AMD [Advanced Micro Devices]

1. The timings are similar to synchronous read timings and asynchronous data polling Timings/Toggle bit Timing.
2. VA = Valid Address. Two read cycles are required to determine status. When the Embedded Algorithm operation is
complete, the toggle bits will stop toggling.
3. RDY is active with data (A18 = 0 in the Configuration Register). When A18 = 1 in the Configuration Register, RDY is active
one clock cycle before data.
4. Data polling requires burst access time delay.

* Valid address for sector protect: A6 = 0, A1 = 1, A0 = 0. Valid address for sector unprotect:A6 = 1, A1 = 1, A0 = 0.
** Command for sector protect is 68h. Command for sector unprotect is 60h.
*** Command for sector protect verify is 48h. Command for sector unprotect verify is 40h.
