25LC256T-E/SN16KV18

Regarding the "25LC256T-E/SN16KV18" parameters, I noticed that there isn't direct detailed parameter information available for this specific model (especially with the "16KV18" suffix) in the provided resources. However, we can make some assumptions and generalizations based on similar products within the "25LC256T-E/SN" series, as "25LC256T-E/SN" is a widely used electrically erasable programmable read-only memory (EEPROM) model produced by Microchip Technology.

Below are the potential parameters for the "25LC256T-E/SN" series of products, based on similar offerings (please note that these parameters may not apply exactly to "25LC256T-E/SN16KV18" as the latter might have specific voltage or temperature range variants):

1. Memory Capacity: 256 Kbit (i.e., 32K x 8)
   • This refers to the storage capacity of the EEPROM in bits, indicating the amount of data it can store.
2. Interface Type: Serial, 4-Wire, SDI, SPI
   • The EEPROM communicates via a serial interface, specifically the SPI (Serial Peripheral Interface) bus, supporting four-wire communication and other protocols.
3. Access Time: 50 ns (or similar value)
   • This is the time from receiving a valid address to the data being stable on the output pins.
4. Data Retention: Up to 200 years
   • The EEPROM has non-volatile storage characteristics, meaning data remains stored even after power is removed.
5. Maximum Clock Frequency: 10 MHz
   • The maximum clock frequency of the EEPROM interface, determining the speed of data transfer.
6. Supply Voltage: 2.5 V to 5.5 V
   • The range of power supply voltages required for the EEPROM to operate normally.
7. Power Current - Maximum: 6 mA (or similar value)
   • The maximum current consumption of the EEPROM during normal operation.
8. Operating Temperature: -40°C to +125°C
   • The temperature range within which the EEPROM can operate normally.
9. Package Type: SOIC-8
   • The package type of the EEPROM, with SOIC standing for Small Outline Integrated Circuit and 8 indicating the number of pins.
10. Programming Voltage: 3.3 V, 5 V
    • The voltages required for programming the EEPROM.

For the specific model "25LC256T-E/SN16KV18," as it may have particular voltage ratings (like 16KV) or temperature ratings (though "18" here might be a misreading or a specific code, as EEPROM temperature ranges are typically given in °C), these specific parameters would need to be sourced from Microchip's official datasheet or by contacting the supplier for accurate information.
