PCA24S08A  
1024 × 8-bit CMOS EEPROM with access protection  
Rev. 01 — 19 January 2010  
Product data sheet  
1. General description  
The PCA24S08A provides 8192 bits of serial Electrically Erasable and Programmable  
Read-Only Memory (EEPROM) organized as 1024 words of 8 bits each. Data bytes are  
received and transmitted via the serial I2C-bus.  
Access permissions limiting reads or writes are set via the I2C-bus to isolate blocks of  
memory from improper access.  
The PCA24S08A is intended to be pin compatible with standard 24C08 serial EEPROM  
devices except for pins 1, 2, and 3, which are address pins in the standard part. Other  
exceptions to the PCA24S08A serial EEPROM data sheet are noted in Section 6.6.  
All bits are sent to or read from the device, most significant bit first, in a manner consistent  
with the 24C08 serial EEPROM. The bit fields in this document are correspondingly listed  
with the MSB on the left and the LSB on the right.  
The EEPROM memory is broken up into 8 blocks of 1 kbit (128 bytes) each. Within each  
block, the memory is physically organized in to 8 pages of 128 bits (16 bytes) each. In  
addition to these 8 kbits, there are two more 128-bit pages that are used to store the  
access protection and ID information. There are a total of 8448 bits of EEPROM memory  
available in the PCA24S08A.  
Access protection (both read and write) is organized on a block basis for block 1 through  
block 7 and on a page and a block basis for block 0. Protection information for these  
blocks and pages is stored in one of the additional pages of EEPROM memory that is  
addressed separately from the main data storage array. SeeSection 6.4 for more details.  
The ID value is located in the ID page of the EEPROM, the second of the additional  
16 byte pages.  
Writes from the serial interface may include from one byte to 16 bytes at a time,  
depending on the protocol followed by the bus master. All page accesses must be  
properly aligned to the internal EEPROM page.  
The EEPROM memory offers an endurance of 100,000 write cycles per byte, with 10 year  
data retention. Writes to the EEPROM take less than 5 ms to complete.  
After manufacturing, all EEPROM bits will be set to a value of ‘1’.
