Additional Details

The SST39SF040-70-4C-PHE-ND is designed for applications requiring a combination of high performance, low power, and reliability. It features a JEDEC standard pinout for easy integration into existing systems. Detailed specifications, including timing characteristics, power consumption, and programming information, can be found in the device's datasheet from Microchip Technology (formerly SST). The '-70' indicates the access time (70ns), '-4C' refers to the temperature grade, and 'PHE' likely denotes the package type (likely a PDIP or similar through-hole package). The '-ND' suffix may be a distributor-specific code.
