Product Description

Microchip AT27C4096-55JU is a high-reliability 4 MB EPROM memory chip designed for industrial and embedded system applications. It is a One Time Programmable (OTP) device housed in a 44-pin PLCC package suitable for through-hole mounting. The memory organization is 256 k x 16 bits, providing ample storage for non-volatile data requiring permanent storage without possibility of erasure.

This EPROM operates with a parallel interface, supporting a supply voltage range from 4.5V to 5.5V, making it compatible with a wide range of electronic systems. It provides a maximum random access time of 55 ns ensuring quick data access. The OTP programming technique means that once programmed, the data cannot be erased or reprogrammed, delivering permanent data retention for critical applications.

The device is designed to operate reliably in harsh industrial conditions with operating temperature range from -40°C to 85°C and typical supply current of 100µA for low power operations. Its dimensions, 16.6 mm square footprint and 4.4 mm height, allow compact PCB layouts. The 44-pin configuration facilitates easy integration on through-hole PCBs.

Microchip EPROMs like the AT27C4096-55JU find use in automotive electronics, industrial controls, embedded system memory storage, and any application demanding permanent, tamper-proof memory. Though it lacks in-system programmability, its one-time programmable nature is advantageous for firmware and fixed data storage after manufacturing.

The EPROM is a non-volatile memory solution with stable data retention. 44-pin PLCC package ensures robust connection and mechanical stability. OTP programming prevents accidental overwrites ensuring data integrity. High operating temperature range suits industrial and automotive sectors.

Compact size supports space-constrained applications. Low power consumption optimizes energy efficiency in embedded systems. Typical use cases include firmware storage, calibration data, and permanent configuration storage.
