Description

The 93C66 is a 4096-bit CMOS non-volatile EEPROM organized as 256 x 16-bit array. This device features MICROWIRE interface which is a 4-wire serial bus with chipselect (CS), clock (SK), data input (DI) and data output (DO) signals. This interface is compatible to many of standard Microcontrollers and Microprocessors.

There are 7 instructions implemented on the FM93C66 for various Read, Write, Erase, and Write Enable/Disable operations. This device is fabricated using Fairchild Semiconductor floating-gate CMOS process for high reliability, high endurance and low power consumption. […]

Description

25Q128FV is 128M-Bit, Flash Memory. A 128M-bit serial flash memory refers to a specific type of non-volatile memory device that can store 128 million bits of data. It is commonly used for storing program code, data, or configuration information in various electronic systems.

The W25Q128FV (128M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. All devices are offered in spacesaving packages.

Highest Performance Serial Flash:

– 104MHz Single, Dual/Quad SPI clocks
– 208/416MHz equivalent Dual/Quad SPI
– 50MB/S continuous data transfer rate
– More than 100,000 erase/program cycles
– More than 20-year data retention

Advanced Security Features:

– Software and Hardware Write-Protect
– Power Supply Lock-Down and OTP protection
– Top/Bottom, Complement array protection
– Individual Block/Sector array protection
– 64-Bit Unique ID for each device
– Discoverable Parameters (SFDP) Register
– 3X256-Bytes Security Registers with OTP locks
– Volatile & Non-volatile Status Register Bits
