Part Number : AT27C1024-55PC
Function : 1Mb (64K x 16) One-time Programmable Read-only Memory
Package : DIP 40 Pin Type
Maker : Atmel Corporation
Pinouts : 
Description :
The Atmel AT27C1024-55PC, AT27C1024 is a low-power, high-performance 1,048,576-bit, one-time programmable, read-only memory (OTP EPROM) organized as 64K by 16 bits. It requires only one 5V power supply in normal read mode operation. Any word can be accessed in less
than 45ns, 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 AT27C1024 typically consumes 15mA. Standby mode supply current is
typically less than 10µA. The AT27C1024 is available in industry-standard, JEDEC-approved, one-time programmable (OTP) PDIP and PLCC packages. The device features two-line control (CE, OE) to eliminate bus contention in high-speed systems
