Features  
Description  
• Max. clock 10 MHz  
The Microchip Technology Inc. 25XX040A* is a 4k-bit  
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, 10MHz  
- Read Current: 5 mA at 5.5V, 10MHz  
- 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. Pb-free (Pure Matte Sn) finish is  
also available.  
- Power-on/off data protection circuitry  
- Write enable latch  
- Write-protect pin  
• High reliability  
Package Types (not to scale)  
- Endurance: 1,000,000 erase/write cycles  
- Data retention: > 200 years  
- ESD protection: > 4000V
