Description:  
• Max. Clock 10 MHz  
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 sep-  
arate data in (SI) and data out (SO) lines. Access to the  
device is controlled through a Chip Select (CS) input.  
• 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  
Communication to the device can be paused via the  
hold pin (HOLD). While the device is paused, transi-  
tions on its inputs will be ignored, with the exception of  
Chip Select, allowing the host to service higher priority  
interrupts.  
• 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  
The 25XX640A is available in standard packages  
including 8-lead PDIP and SOIC, and advanced  
packaging including 8-lead MSOP, 8-lead TSSOP, DFN  
and TDFN.  
- Power-on/off data protection circuitry  
- Write enable latch  
- Write-protect pin  
• Sequential Read  
• High Reliability  
Package Types (not to scale)  
- Endurance: 1,000,000 erase/write cycles  
- Data retention: > 200 years  
- ESD protection: > 4000V
