It requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 100 ns, eliminating the need for speed-reducing WAIT states. The x16 organization makes this part ideal for high-performance 16- and 32-bit (continued) microprocessor systems. 8-Megabit (512K x 16 or 1024K x 8) UV Erasable EPROM AT27C800 Preliminary Pin Configurations Pin Name A0 - A18 O0 - O15 O15/A-1 BYTE/VPP CE OE NC Function Addresses Outputs Output/Address Byte Mode/ Program Supply Chip Enable Output Enable No Connect CDIP, PDIP Top View A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CE GND OE O0 O8 O1 O9 O2 O10 O3 O11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 NC A8 A9 A10 A11 A12 A13 A14 A15 A16 BYTE/VPP GND O15/A-1 O7 O14 O6 O13 O5 O12 O4 VCC SOIC (SOP) NC A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 CE GND OE O0 O8 O1 O9 O2 O10 O3 O11 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 NC NC A8 A9 A10 A11 A12 A13 A14 A15 A16 BYTE/VPP GND O15/A-1 O7 O14 O6 O13 O5 O12 O4 VCC TSOP Type 1 A15 A14 A13 A12 A11 A10 A9 A8 NC NC NC NC NC NC NC...
