The AT27BV4096 is a high performance, low power, low voltage 4,194,304 bit one-time programmable read only memory (OTP EPROM) organized as 256K by 16 bits. It requires only one supply in the range of 2.7V to 3.6V in normal read mode operation. The by-16 organization makes this part ideal for portable and handheld 16 and 32 bit microprocessor based systems using either regulated or unregulated battery power.
The AT27BV4096 is a high‑performance, low‑power, low‑voltage 4‑Megabit OTP EPROM organized as 256K × 16 bits. It operates from a single unregulated battery supply (2.7 V‑3.6 V) or a standard 5 V ± 10 % supply, making it suitable for portable and handheld systems. The device features fast 120 ns read access, low active power (29 mW at 5 MHz, VCC = 3.6 V) and very low standby current (<1 µA at 3 V).
Electrical specifications include 2,000 V ESD protection, 200 mA latchup immunity, CMOS/TTL‑compatible I/O, and a rapid programming algorithm (typical 100 µs/word). The part is offered in JEDEC‑standard 44‑lead PLCC and 40‑lead TSOP (10 × 14 mm) packages and includes an integrated product identification code for programming equipment.
