Product Description
Microchip AT27C1024-70JU is a high-reliability 1 MB EPROM (Erasable Programmable Read-Only Memory) designed with a 44-pin PLCC package and parallel interface.
This OTP memory device offers fast access with a maximum random access time of 70ns and an organization of 64K x 16 bits, ideal for a range of electronic applications needing stable one-time-programmable memory.
With a through-hole mount type and a compact form factor of 16.6mm by 16.6mm by 4.4mm, it facilitates easy integration into printed circuit boards in industrial, commercial, and laboratory equipment.
The device operates reliably between -40°C and 85°C, with power supply requirements ranging from a minimum of 4.5V to a maximum of 5.5V and a low supply current rating of 100μA, ensuring efficient power utilization.
This memory chip does not support in-system programmability and is not UV-erasable, providing permanent data storage once programmed, suitable for secure, non-volatile data retention.
Memory size of 1 MB with 64K x 16-bit organization. OTP programming technique with no risk of data loss from UV exposure. Through-hole PLCC packaging with 44 pins ensures durability and ease of assembly. Wide operating temperature range for diverse environmental conditions.
Low supply current enhances energy efficiency. This EPROM is widely used in industrial electronic applications, embedded systems, control units, and other environments where permanent on-chip data storage is critical.
