Description:  
• Max. clock 10 MHz  
The Microchip Technology Inc. 25AA160A/B,  
25LC160A/B (25XX160A/B*) are 16 Kbit Serial  
Electrically Erasable PROMs. The memory is accessed  
• Low-power CMOS technology  
• 2048 x 8-bit organization  
• 16 byte page (‘A’ version devices)  
• 32 byte page (‘B’ version devices)  
• Write cycle time: 5 ms max.  
• Self-timed erase and write cycles  
• Block write protection:  
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.  
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.  
- Protect none, 1/4, 1/2 or all of array  
• Built-in write protection:  
- Power-on/off data protection circuitry  
- Write enable latch  
The 25XX160A/B is available in standard Pb-free pack-  
ages including 8-lead PDIP and SOIC, and advanced  
packaging including 8-lead MSOP, and 8-lead TSSOP.  
- Write-protect pin  
• Sequential read  
• High reliability:  
- Endurance: 1,000,000 erase/write cycles  
- Data retention: > 200 years  
- ESD protection: > 4000V  
Temperature ranges supported:
