STMicroelectronics M27C4002-10C1 EPROM

The M27C4002-10C1 is a high-speed 4 Mbit (4,194,304 bits) EPROM (Erasable Programmable Read-Only Memory) from the renowned semiconductor manufacturer, STMicroelectronics. This memory device is designed for applications that require fast access times and high data storage capacity. With its 10ns access time, it is particularly well-suited for performance-intensive applications.

Constructed with STMicroelectronics' reliable CMOS technology, the M27C4002-10C1 offers a non-volatile storage solution that can retain data even when the power is turned off. This makes it ideal for use in firmware storage, microcontroller systems, and other embedded applications where long-term data retention is crucial.

Key Features:

• Memory Size: 4 Mbit
• Access Time: 10ns
• Programming Voltage: 12.75V ± 0.25V
• Single 5V ± 10% Power Supply: Simplifies power management in embedded systems.
• Organized as 256K x 16: Allows for efficient data management and easy integration into 16-bit systems.
• Two-Line Control Function: Provides a simple and effective way to manage the chip's operation.
• Programmable Chip Enable & Output Enable: Offers flexibility in system design and power saving options.

The M27C4002-10C1 also features a transparent lid that allows the user to expose the chip to ultraviolet light to erase the data, enabling reuse and reprogramming of the EPROM. This erasure feature is particularly useful during the development phase of a project or when updating the firmware in the field.

For security purposes, the device includes a programmable security bit that can be used to protect sensitive data. Once programmed, this bit prevents the reading of specific blocks, ensuring that proprietary information remains confidential.

STMicroelectronics has designed the M27C4002-10C1 with industry-standard packaging and pinouts, making it a drop-in replacement for other standard EPROMs. This compatibility ensures that it can be easily integrated into existing designs without the need for significant redesigns.

Overall, the M27C4002-10C1 is a robust and reliable memory component that offers a combination of speed, capacity, and features suitable for a wide array of applications that require stable and long-term data storage.
