|
|
|
|
|
|
| |||
|
|
|
|
|
|
|
| asserted LOW, addresses presented to the device | |
|

|
|
|
|

| are captured in the address registers. A1: A0 are | |
|
|
|
|
|
|
|
| also loaded into the burst counter. When ADSP and | |
|
|
|
|
|
|
|
| ADSC are both asserted, only ADSP is recognized. | |
|
|
|
|
|
|
|
| ASDP is ignored when CE1 is deasserted HIGH. | |

|
|
|
|
|
|
|
| LOW, addresses presented to the device are | |
|
|
|
|
|
|
|
| captured in the address registers. A1: A0 are also | |
|
|
|
|
|
|

| ZZ | 64 |
| T7 | H11 | Input- | ZZ “sleep” Input, active HIGH. When asserted | ||
|
|
|
|
|
|
| Asynchronous | HIGH places the device in a | |
|
|
|
|
|
|
|
| “sleep” condition with data integrity preserved. For | |
|
|
|
|
|
|
|
| normal operation, this pin has to be LOW or left | |
|

|
|
|
|
| floating. ZZ pin has an internal | |

|
| ||
| DQs, | 58,59,62, |
| P7,K7, | J10,K10, | I/O- | Bidirectional Data I/O lines. As inputs, they feed | ||
| DQPs | 63,68,69, |
| G7,E7, | L10,M10, | Synchronous | into an | ||
|
|
| 72,73,8,9, | F6,H6,L6,N6, | D11,E11, |
| rising edge of CLK. As outputs, they deliver the data | ||

| D1, | F11,G11,J1,K1 |
| contained in the memory location specified by the | |

| addresses presented during the previous clock rise | |

| of the read cycle. The direction of the pins is | |
|
|
|
|
| G2,K2, | G2,C11,N1 |
| controlled by OE. When OE is asserted LOW, the | |
|
|
|
|
| M2,D6, |
|
| pins behave as outputs. When HIGH, DQs and | |
|
|
|
|
