(not available for PBGA) 92 (for TA Ver- sion only) CE2 Input- Synchronous Chip Enable: This active LOW input is used to enable the de- vice. Not available for B and T package versions. 4F 86 OE Input Output Enable: This active LOW asynchronous input enables the data output drivers. 4G 83 ADV Input- Synchronous Address Advance: This active LOW input is used to control the internal burst counter. A HIGH on this pin generates wait cycle (no address advance). 4A 84 ADSP Input- Synchronous Address Status Processor: This active LOW input, along with CE being LOW, causes a new external address to be registered and a Read cycle is initiated using the new address. 4B 85 ADSC Input- Synchronous Address Status Controller: This active LOW input causes de- vice to be deselected or selected along with new external ad- dress to be registered. A Read or Write cycle is initiated de- pending upon write control inputs. 3R 31 MODE Input- Static Mode: This input selects the burst sequence. A LOW on this pin selects Linear Burst. A NC or HIGH on this pin selects Interlinear Burst. 7T 64 ZZ Input- Asynchronous Snooze: This active HIGH input puts the device in low power consumption standby mode. For normal operation, this input has to be either LOW or NC (No Connect). (a) 6D, 7E, 6F, 7G, 6H, 7K, 6L, 6N, 7P (b) 1D, 2E, 2G, 1H, 2K, 1L, 2M, 1N, 2P (a) 58, 59, 62, 63, 68, 69, 72, 73, 74 (b) 8, 9, 12, 13, 18, 19, 22, 23, 24 DQa DQb Input/ Output Data Inputs/Outputs: Low Byte is DQa. High Byte is DQb. Input data must meet set up and hold times around the rising edge of CLK. 2U 3U 4U 38 39 43 for B and T version TMS TDI TCK Input IEEE 1149.1 test inputs. LVTTL-level inputs. Not available for TA package version. 5U 42 for B and T version TDO Output IEEE 1149.1 test output. LVTTL-level output. Not available for TA package version. 4C, 2J, 4J, 6J, 4R 15, 41,65, 91 VCC Supply Core power Supply: +3.3V –5% and +10% 3D, 5D, 3E, 5E, 3F, 5F, 5G, 3H, 5H, 3K, 5K, 3L, 3M, 5M, 3N, 5N, 3P, 5P 5, 10, 17, 21, 26, 40, 55, 60, 67, 71, 76, 90 VSS Ground Ground: GND. 1A, 7A, 1F, 7F, 1J, 7J, 1M, 7M, 1U, 7U 4, 11, 20, 27, 54, 61, 70, 77 VCCQ I/O Supply Output Buffer Supply: +2.5V or +3.3V. 1B, 7B, 1C, 7C, 2D, 4D, 7D, 1E, 6E, 2F, 1G, 6G, 2H, 7H, 3J, 5J, 1K, 6K, 2L, 4L, 7L, 6M, 2N, 7N, 1P, 6P, 1R, 5R, 7R, 1T, 4T, 6U 1-3, 6, 7, 14, 16, 25, 28-30, 51-53, 56, 57, 66, 75, 78, 79, 80, 95, 96 38, 39, 42 for TA Version NC - No Connect: These signals are not internally connected. User can leave it floating or connect it to VCC or VSS. 512K X 18 Pin Descriptions (continued) X18 PBGA Pins X18 QFP Pins Name Type Description |
