4MBIT Parallel EPROM IC 256K X 16 One Time AT27C4096-90JU

The Atmel AT27C4096 is a low-power, high-performance, 4,194,304-bit, one-time programmable, read-only memory (OTP EPROM) organized as 256K by 16 bits.

• Fast read access time - 55ns
• Low-power CMOS operation: 100µA max standby, 40mA max active at 5MHz
• JEDEC standard packages: 40-lead PDIP, 44-lead PLCC
• Direct upgrade from 512Kbit, 1Mbit, and 2Mbit Atmel® EPROMs
• 5V ± 10% supply
• High-reliability CMOS technology: 2,000V ESD protection, 200mA latchup immunity
• Rapid programming algorithm - 50µs/word (typical)
• CMOS- and TTL-compatible inputs and outputs
• Integrated product identification code
• Industrial temperature range
• Green (Pb/halide-free) packaging option

The device requires a single 5V power supply in normal read mode operation. Any word can be accessed in less than 55ns, eliminating the need for speed reducing WAIT states. The x16 organization makes this part ideal for high-performance, 16- and 32-bit microprocessor systems.

In read mode, the AT27C4096 typically consumes 15mA. Standby mode supply current is typically less than 10µA.

According to the standard export packaging. Customers can choose from cartons, wooden cases and wooden pallets according to their own requirements.
