25AA640A Product details

Description:
The Microchip Technology Inc. 25AA640A/25LC640A (25XX640A*) are 64 kbit Serial Electrically Erasable PROMs. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input.

Features:
• Max. Clock 10 MHz
• Low-Power CMOS Technology:
    - Max. Write Current: 5 mA at 5.5V, 10 MHz
    - Read Current: 5 mA at 5.5V, 10 MHz
    - Standby Current: 1 μA at 5.5V
• 8192 x 8-bit Organization
• 32 Byte Page
• Self-Timed Erase and Write Cycles (5 ms max.)
• Block Write Protection:
    - Protect none, 1/4, 1/2 or all of array
• Built-In Write Protection:
    - Power-on/off data protection circuitry
    - Write enable latch
    - Write-protect pin
• Sequential Read
• High Reliability:
    - Endurance: 1,000,000 erase/write cycles
    - Data retention: > 200 years
    - ESD protection: > 4000V
• Temperature Ranges Supported:
    - Industrial (I): -40°C to +85°C
    - Automotive (E): -40°C to +125°C
