It requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 70 ns, eliminating the need for speed-reducing WAIT states. The by-16 organization makes this part ideal for high-performance 16- and 32- bit microprocessor systems. 4-Megabit (256K x 16 or 512K x 8) OTP EPROM AT27C400 Preliminary Pin Configurations Note: Both GND pins must be connected. Pin Name Function A0 - A17 Addresses O0 - O15 Outputs O15/A-1 Output/Address BYTE/VPP Byte Mode/ Program Supply CE Chip Enable OE Output Enable NC No Connect TSOP Type 1 |
