1K-4K SPI Serial EEPROM High Temp Family Data Sheet  
Features:  
Description:  
• Max. Clock 5 MHz  
Microchip Technology Inc. 25LCXXXA* devices are  
low-density 1 through 4 Kbit Serial Electrically Eras-  
able PROMs (EEPROM). The devices are organized in  
blocks of x8-bit memory and support the Serial Periph-  
eral Interface (SPI) compatible serial bus architecture.  
Byte-level and page-level functions are supported.  
• Low-Power CMOS Technology:  
- Max. Write Current: 5 mA at 5.5V, 5 MHz  
- Read Current: 5 mA at 5.5V, 5 MHz  
- Standby Current: 10 μA at 5.5V  
• 128 x 8 through 512 x 8-bit Organization  
• Byte and Page-level Write Operations  
• Self-Timed Erase and Write Cycles (6 ms max.)  
• Block Write Protection:  
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.  
- Protect none, 1/4, 1/2 or all of array  
• Built-in Write Protection:  
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.  
- Power-on/off data protection circuitry  
- Write enable latch  
- Write-protect pin  
The 25LCXXXA is available in a standard 8-lead SOIC  
package. The package is Pb-free and RoHS  
Compliant.  
• Sequential Read  
• High Reliability:  
- Endurance: >1M erase/write cycles  
- Data retention: > 200 years  
- ESD protection: > 4000V
