STMicroelectronics M27C64A-20F1 EPROM
The M27C64A-20F1 is a high-speed 64 Kbit EPROM (Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This memory device is designed to deliver reliable non-volatile storage solutions for a wide range of applications, including embedded systems, microcontroller units, and various other digital circuits where program code or data storage is essential.
With a storage capacity of 64 kilobits, the M27C64A-20F1 allows for the storage of 8,192 bytes of data. It is organized as 8K x 8 bits, which means it has 8,000 words of 8 bits each. The '-20F1' suffix indicates its access time of 200 ns, making this EPROM suitable for systems that require relatively fast data retrieval without sacrificing the stability and reliability of non-volatile memory.
The device comes in a 28-pin CERDIP (Ceramic Dual In-line Package) or PDIP (Plastic Dual In-line Package), ensuring robust physical protection and compatibility with standard IC sockets or direct PCB (Printed Circuit Board) mounting. It operates within a supply voltage range of 4.5V to 5.5V, which is typical for many logic circuits and microcontrollers, allowing for seamless integration into existing designs.
One of the key features of the M27C64A-20F1 is its programmability. Users can erase the existing data with exposure to ultraviolet light, thanks to the quartz window on top of the chip. After erasure, the device can be reprogrammed with new data or code using a compatible EPROM programmer. This feature provides flexibility for development, testing, and updating firmware in the field.
Additional characteristics include its extended temperature range, ensuring operation in diverse environmental conditions, and low power consumption, which is critical for portable and energy-sensitive applications. The M27C64A-20F1 also supports the industry-standard programming algorithm, making it compatible with most EPROM programmers.
In summary, the STMicroelectronics M27C64A-20F1 EPROM is a versatile and reliable choice for designers who require a non-volatile memory solution that offers ample storage, ease of use, and compatibility with a broad range of applications and devices.
