Notes
1. CY7C024AV and CY7C024BV are functionally identical.
2. IO8âIO15 for x16 devices; IO9âIO17 for x18 devices.
3. IO0âIO7 for x16 devices; IO0âIO8 for x18 devices.
4. A0âA11 for 4K devices; A0âA12 for 8K devices; A0âA13 for 16K devices.
5. BUSY is an output in master mode and an input in slave mode.
