CY15B016Q  
16-Kbit (2K × 8) Serial (SPI) Automotive-A  
F-RAM  
16-Kbit (2K  
× 8) Serial (SPI) Automotive-A F-RAM  
Features  
Functional Description  
16-Kbit ferroelectric random access memory (F-RAM) logically  
organized as 2K × 8  
High-endurance 100 trillion (1014) read/writes  
151-year data retention (See the Data Retention and  
Endurance table)  
NoDelay™ writes  
Advanced high-reliability ferroelectric process  
The CY15B016Q is a 16-Kbit nonvolatile memory employing an  
advanced ferroelectric process. A ferroelectric random access  
memory or F-RAM is nonvolatile and performs reads and writes  
similar to a RAM. It provides reliable data retention for 151 years  
while eliminating the complexities, overhead, and system level  
reliability problems caused by serial flash, EEPROM, and other  
nonvolatile memories.  
Very fast serial peripheral interface (SPI)  
Up to 20 MHz frequency  
Direct hardware replacement for serial flash and EEPROM  
Supports SPI mode 0 (0, 0) and mode 3 (1, 1)  
Unlike serial flash and EEPROM, the CY15B016Q performs  
write operations at bus speed. No write delays are incurred. Data  
is written to the memory array immediately after each byte is  
successfully transferred to the device. The next bus cycle can  
commence without the need for data polling. In addition, the  
product offers substantial write endurance compared with other  
nonvolatile memories. The CY15B016Q is capable of supporting  
1014 read/write cycles, or 100 million times more write cycles  
than EEPROM.  
Sophisticated write protection scheme  
Hardware protection using the Write Protect (WP) pin  
Software protection using Write Disable instruction  
Software block protection for 1/4, 1/2, or entire array  
These capabilities make the CY15B016Q ideal for nonvolatile  
memory applications requiring frequent or rapid writes.  
Examples range from data collection, where the number of write  
cycles may be critical, to demanding industrial controls where the  
long write time of serial flash or EEPROM can cause data loss.  
Low power consumption  
200 A active current at 1 MHz  
3 A (typ) standby current  
Low-voltage operation: VDD = 2.7 V to 3.6 V  
Automotive-A temperature: –40 C to +85 C  
8-pin small outline integrated circuit (SOIC) package  
Restriction of hazardous substances (RoHS) compliant  
The CY15B016Q provides substantial benefits to users of serial  
EEPROM or flash as a hardware drop-in replacement. The  
CY15B016Q uses the high-speed SPI bus, which enhances the  
high-speed write capability of F-RAM technology. The device  
specifications are guaranteed over an automotive-a temperature  
range of –40 C to +85 C.
