The Microchip Technology AT27C1024-45PU is a high-performance, low-power 1,048,576-bit EPROM organized as 64K x 16 bits. This one-time programmable (OTP) memory requires a single 5V power supply for normal read operations, with any word accessible in under 45ns, eliminating the need for wait states in high-speed systems.
Designed for 16- and 32-bit microprocessor systems, the AT27C1024 offers a 1Mbit storage capacity, ideal for reliable firmware storage. It operates within a voltage range of 4.5V to 5.5V and features a fast 45ns read access time. The device consumes low power, with a typical active current of 15mA at 5MHz and a standby current of less than 10µA.
This EPROM is available in a JEDEC-standard 40-lead PDIP package, suitable for through-hole mounting. It includes two-line control (CE, OE) to prevent bus contention in complex systems. The device also features a rapid programming algorithm for efficient production use, with programming times typically at 100µs/word, and includes an integrated product identification code for automatic device recognition by programming equipment.
With industrial and automotive temperature ranges supported (-40°C to 85°C TC), the AT27C1024 is built using high-reliability CMOS technology, offering 2000V ESD protection and 200mA latchup immunity. A green (Pb/halide-free) packaging option is also available.
