Description:  
• 20 MHz max. Clock Speed  
• Byte and Page-level Write Operations:  
- 128-byte page  
The Microchip Technology Inc. 25LC512 is a 512 Kbit  
serial EEPROM memory with byte-level and page-level  
serial EEPROM functions. It also features Page, Sector  
and Chip erase functions typically associated with  
Flash-based products. These functions are not required  
for byte or page write operations. 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 by a Chip  
Select (CS) input.  
- 5 ms max.  
- No page or sector erase required  
• Low-Power CMOS Technology:  
- Max. Write Current: 5 mA at 5.5V, 20 MHz  
- Read Current: 10 mA at 5.5V, 20 MHz  
- Standby Current: 1A at 2.5V (Deep power-  
down)  
• Electronic Signature for Device ID  
• Self-Timed Erase and Write cycles:  
- Page Erase (5 ms, typical)  
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.  
- Sector Erase (10 ms/sector, typical)  
- Bulk Erase (10 ms, typical)  
• Sector Write Protection (16K byte/sector):  
- Protect none, 1/4, 1/2 or all of array  
The 25LC512 is available in standard packages includ-  
ing 8-lead PDIP, SOIC, and advanced 8-lead DFN  
package. All packages are Pb-free and RoHS  
compliant.  
• Built-In Write Protection:  
- Power-on/off data protection circuitry  
- Write enable latch  
- Write-protect pin  
• High Reliability:  
- Endurance: 1 Million erase/write cycles  
Package Types (not to scale)  
- Data Retention: >200 years  
- ESD Protection: >4000V
