CY15E016Q  
16-Kbit (2K × 8) Serial (SPI) Automotive  
F-RAM  
16-Kbit (2K  
× 8) Serial (SPI) Automotive F-RAM  
Features  
Functional Description  
16-Kbit ferroelectric random access memory (F-RAM) logically  
organized as 2K × 8  
High-endurance 10 trillion (1013) read/writes  
121-year data retention (See the Data Retention and  
Endurance table)  
NoDelay™ writes  
Advanced high-reliability ferroelectric process  
The CY15E016Q 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 121 years  
while eliminating the complexities, overhead, and system level  
reliability problems caused by serial flash, EEPROM, and other  
nonvolatile memories.  
Unlike serial flash and EEPROM, the CY15E016Q 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 CY15E016Q is capable of supporting  
1013 read/write cycles, or 10 million times more write cycles than  
EEPROM.  
Very fast serial peripheral interface (SPI)  
Up to 16 MHz frequency  
Direct hardware replacement for serial flash and EEPROM  
Supports SPI mode 0 (0, 0) and mode 3 (1, 1)  
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 CY15E016Q 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  
300 μA active current at 1 MHz  
10 μA (typ) standby current at +85 °C  
Voltage operation: VDD = 4.5 V to 5.5 V  
Automotive-E temperature: –40 °C to +125 °C  
8-pin small outline integrated circuit (SOIC) package  
AEC Q100 Grade 1 compliant  
The CY15E016Q provides substantial benefits to users of serial  
EEPROM or flash as a hardware drop-in replacement. The  
CY15E016Q 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-e temperature  
range of –40 °C to +125 °C.  
Restriction of hazardous substances (RoHS) compliant
