Description  
• Max. clock 10 MHz  
The Microchip Technology Inc. 25AA256/25LC256  
(25XX256*) are 256k-bit 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  
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: 1 µA at 5.5V  
• 32,768 x 8-bit organization  
• 64 byte page  
• Self-timed ERASE and WRITE cycles (5 ms  
max.)  
Communication to the device can be paused via the  
hold pin (HOLD). While the device is paused,  
transitions on its inputs will be ignored, with the  
exception of Chip Select, allowing the host to service  
higher priority interrupts.  
• Block write protection  
- Protect none, 1/4, 1/2 or all of array  
• Built-in write protection  
The 25XX256 is available in standard packages  
including 8-lead PDIP and SOIC, and advanced  
packaging including 8-lead DFN and 8-lead TSSOP.  
Pb-free (Pure Sn) finish is also available.  
- 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
