AT27C800

AT27C800 Features Read Access Time - 100 ns Word-wide or Byte-wide Configurable 8-Megabit Flash and Mask ROM Compatable Low Power CMOS Operation - 100 µA Maximum Standby - 50 mA Maximum Active at 5 MHz Wide Selection of JEDEC Standard Packages - 42-Lead 600 mil Cerdip and PDIP - 44-Lead SOIC (SOP) - 48-Lead TSOP (12 mm x 20 mm) 5V ± 10% Power Supply High Reliability CMOS Technology - 2,000 ESD Protection - 200 mA Latchup Immunity RapidTM Programming Algorithm - 50 µs/word (typical) CMOS and TTL Compatible Inputs and Outputs Integrated Product Identification Code Commercial and Industrial Temperature Ranges Description The AT27C800 is a low-power, high performance 8,388,608-bit UV erasable programmable read only memory (EPROM) organized as either 512K by 16 or 1024K by 8 bits. 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...
