S25FL064LABMFA001

The S25FL064LABMFA001, also known as the 8-lead low-voltage serial flash, is an integrated serial flash memory chip from Cypress Semiconductor. It is a small and fast memory device primarily intended for embedded applications. It is widely used for non-volatile memory storage of small digital data as well as for code storage or program/data execution. It offers an attractive combination of fast access, zero pin-count for 8-lead package, and an upgrade path for customers demanding larger or faster memories.

The S25FL064LABMFA001 is a 64 Mbit (8 megabyte) serial flash memory device. It is divided into eight (8) memory array blocks and each one can be individually enabled making programming and erasing much easier than with conventional parallel flash memory devices. It contains two data buses, two input/output pins and two select/enable pins. The top selection and enable inputs are used to select a memory block and enable it for programming or erasure. This device features an 87MHz clock rate, an internal clock generator, automatic sector protection and several different read, write and erase operations.

The primary application field for this device is embedded portable device memory storage. It is ideal for use in low-power portable applications that require non-volatile memory for data/code storage. It can also be used for code execution, as a firmware hub or for secure storage. It is used in a wide range of products from macro cellular phones, digital cameras, PDAs and routers to WiFi based products, logic controllers and data communications equipment.

The working principle of this device is fairly simple. It is based on the fact that each memory block contains a small number of memory areas that can be individually written and erased. This enables the selective programming and erasure of any of the memory sections without affecting the rest. The two select/enable inputs (top and bottom) are used to select a specific memory block and enable it for programming or erasure. The two data bus pins (data in and data out) are used to write/erase data to/from the selected memory block. The two input/output pins (high and low) are used to read/write data from/to the memory block.

In conclusion, the S25FL064LABMFA001 is an 8-lead low-voltage serial flash memory device used for non-volatile memory storage of small digital data. It is primarily used for embedded applications and is an ideal choice for low-power portable devices. It is composed of two data buses, two select/enable input pins and two input/output pins and works on the basic principle of selection and enablement of memory blocks for programming and erasure. Therefore, the S25FL064LABMFA001 is a practical and reliable choice for storage and code execution of embedded portable applications.
