AM29PDL128G70 SPANSION [SPANSION], AM29PDL128G70 Datasheet - Page 44

• Manufacturer Part Number: AM29PDL128G70
• Description: 128 Megabit (8 M x 16-Bit/4 M x 32-Bit) CMOS 3.0 Volt-only, Simultaneous Read/ Write Flash Memory with VersatileIO Control
• Manufacturer: SPANSION [SPANSION]

Legend:
BA = Address of bank switching to autoselect mode, bypass mode, or
erase. Determined by A21:A19, see Tables
PA = Program Address (A21:A-1). Addresses latch on falling edge of
WE# or CE# pulse, whichever happens later.
PD = Program Data (DQ15:DQ0) written to location PA. Data latches
on rising edge of WE# or CE# pulse, whichever happens first.
RA = Read Address (A21:A-1).
Notes:
1.
2. All values are in hexadecimal.
3. Shaded cells in table denote read cycles. All other cycles are
4. During unlock and command cycles, when lower address bits are
5. No unlock or command cycles required when bank is reading
6. Reset command is required to return to reading array (or to
7. Cycle 4 of autoselect command sequence is a read cycle. See
8. The data is 80h for factory locked and 00h for not factory locked.
