Microchip Technology, Inc. Memory AT27BV512-90JI

The AT27BV512-90JI is a 512Kbit one-time programmable (OTP) EPROM memory device organized as 64K x 8 bits. It operates within a dual voltage range of 2.7V to 3.6V or at a standard 5V supply, making it suitable for both regulated and unregulated battery-powered applications. The device features a fast read access time of 90 ns and low power consumption, with a maximum standby current of 20 ¬µA and active current of 29 mW at 5 MHz. This memory chip is available in JEDEC standard surface mount packages, including 32-Lead PLCC, 28-Lead SOIC, and 28-Lead TSOP. It is designed for high reliability with 2,000V ESD protection and 200 mA latchup immunity. The Rapid,Ñ¢ programming algorithm allows for efficient programming at a typical time of 100 ¬µs per byte. The AT27BV512-90JI is compatible with both CMOS and TTL logic levels, making it versatile for various system designs. It is suitable for commercial and industrial temperature ranges from -40¬8C to +85¬8C.
