The HN27C4096G-12 is a 4-Megabit (512K x 8) CMOS EPROM (Erasable Programmable Read-Only Memory) manufactured by Hitachi, Ltd. It's designed for applications requiring non-volatile storage of data or program code. The "-12" denotes an access time of 120ns.

Applications

• Embedded systems
• Microcontroller program storage
• Industrial control equipment
• Telecommunications equipment
• Data loggers
• BIOS storage in older computer systems

Features

• 4-Megabit (512K x 8 bit) organization
• Fast access time: 120 ns
• Single 5V power supply
• CMOS technology for low power consumption
• TTL compatible inputs and outputs
• Programmable using standard EPROM programmers
• Erasable with ultraviolet (UV) light

Benefits

• Non-Volatile Storage: Data is retained even when power is removed.
• Fast Access Time: 120ns access time allows for quick data retrieval.
• Easy Programming: Can be programmed using readily available EPROM programmers.
• Low Power Consumption: CMOS technology minimizes power consumption.

Additional Details

The HN27C4096G-12 is typically housed in a 32-pin DIP (Dual In-line Package) or a surface-mount package. It requires a 5V power supply for operation. The memory array is organized as 512K words of 8 bits each. Erasing the EPROM requires exposure to UV light for a specified duration. The device has an operating temperature range, as specified in the manufacturer's datasheet. Detailed pinout information and programming specifications are also available in the datasheet.
