Description:  
• Max. Clock 10 MHz  
The Microchip Technology Inc. 25XX040A* is a 4 Kbit  
Serial Electrically Erasable Programmable Read-Only  
Memory (EEPROM). 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.  
• 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: 5 μA at 5.5V  
• 512 x 8-Bit Organization  
• Write Page mode (up to 16 bytes)  
• Sequential Read  
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 25XX040A is available in standard packages  
including 8-lead PDIP and SOIC, and advanced  
packages including 8-lead MSOP, 8-lead TSSOP  
and rotated TSSOP, 8-lead 2x3 DFN, and 6-lead  
SOT-23.  
- Power-on/off data protection circuitry  
- Write enable latch  
- Write-protect pin  
• High Reliability:  
- Endurance: 1,000,000 Erase/Write cycles  
- Data retention: > 200 years  
- ESD protection: > 4000V
