The MD2732/B, supplied by Rochester Electronics, is an EPROM (Erasable Programmable Read-Only Memory) device. This memory chip is designed for applications requiring non-volatile storage of data and program code. As an EPROM, the MD2732/B can be erased by exposure to ultraviolet light and reprogrammed, offering a degree of flexibility for development and prototyping.

Applications

• Firmware storage in legacy systems: Used to store boot code and operating system kernels in older computers and embedded systems.
• Program storage for microcontrollers: Stores the application code for microcontrollers in various electronic devices.
• Data storage in industrial control equipment: Retains calibration data, configuration settings, and other critical information in industrial machinery.
• Game cartridges for vintage gaming consoles: Used to store game data and program code in older gaming systems.
• Embedded system prototyping: Provides a flexible storage solution for developing and testing embedded system software.

Features

• 4096 x 8-bit organization (32KB capacity): Offers a substantial amount of memory for storing program code and data.
• Erasable and programmable: Allows for reprogramming after erasure with ultraviolet light.
• Static operation: Requires no clock or refresh signals for operation.
• TTL compatible inputs and outputs: Ensures compatibility with standard logic devices.

Additional Details

The MD2732/B EPROM requires a specific UV light source for erasure. The erasure process typically takes several minutes. Once erased, the device can be programmed using an EPROM programmer. It's important to handle the device with care to avoid electrostatic discharge (ESD) damage. Rochester Electronics provides this device as part of their continued support for legacy components, ensuring that older systems can continue to be maintained and operated. The device is commonly used in applications where long-term data retention and occasional reprogramming are required.
