STMicroelectronics 27C512-12F1 EPROM Overview

The 27C512-12F1 is a high-speed 512 Kbit EPROM (Erasable Programmable Read-Only Memory) manufactured by STMicroelectronics. This memory device is designed for performance-driven applications where reliable and durable non-volatile memory storage is critical. With a 64K x 8-bit organization, it provides ample storage for firmware, boot code, or other data that requires long-term retention without power.

The '12F1' in the product name indicates the access time of the EPROM, which is 120 ns (nanoseconds), making this component suitable for systems that require fast read operations. This speed, combined with a wide operating voltage range, ensures compatibility with a variety of microprocessors and digital systems.

Key Features of the 27C512-12F1

• Memory Capacity: 512 Kbit (64K x 8-bit)
• Access Time: 120 ns
• Single 5V Power Supply: The device operates on a 5V ± 10% supply voltage, which is standard for many digital systems.
• Extended Temperature Range: The device is designed to operate reliably over an extended temperature range, making it suitable for industrial applications.
• Programming Voltage (VPP): 12.75V ± 0.25V, which is required for programming the EPROM.
• Two-Line Control Function: Simplifies system design by allowing the use of common bus structures for both programming and normal read operations.
• Static Operation: No clocks or refreshes are required, which simplifies the interfacing with microprocessors and reduces power consumption.
• Transparent Latch: Enables the user to latch the address and data information using a two-phase write operation.
• ECMOS Technology: Provides low power consumption and high reliability.
