CY15E016J 2 16-Kbit (2K 8) Serial (I C) Automotive-A F-RAM 16-Kbit (2K 8) Serial (I2C) Automotive-A F-RAM Features Functional Description The CY15E016J is a 16-Kbit nonvolatile memory employing an 16-Kbit ferroelectric random access memory (F-RAM) logically advanced ferroelectric process. A ferroelectric random access organized as 2K 8 14 memory or F-RAM is nonvolatile and performs reads and writes High-endurance 100 trillion (10 ) read/writes similar to a RAM. It provides reliable data retention for 151 years 151-year data retention (See the Data Retention and while eliminating the complexities, overhead, and system-level Endurance table) reliability problems caused by EEPROM and other nonvolatile NoDelay writes memories. Advanced high-reliability ferroelectric process 2 Unlike EEPROM, the CY15E016J performs write operations at Fast 2-wire Serial interface (I C) bus speed. No write delays are incurred. Data is written to the Up to 1-MHz frequency memory array immediately after each byte is successfully 2 Direct hardware replacement for serial (I C) EEPROM transferred to the device. The next bus cycle can commence Supports legacy timings for 100 kHz and 400 kHz without the need for data polling. In addition, the product offers substantial write endurance compared with other nonvolatile Low power consumption memories. Also, F-RAM exhibits much lower power during writes 100 A active current at 100 kHz than EEPROM since write operations do not require an internally 4 A (typ) standby current elevated power supply voltage for write circuits. The CY15E016J 14 Voltage operation: V = 4.5 V to 5.5 V DD is capable of supporting 10 read/write cycles, or 100 million times more write cycles than EEPROM. Automotive-A temperature: 40 C to +85 C These capabilities make the CY15E016J ideal for nonvolatile 8-pin small outline integrated circuit (SOIC) package memory applications, requiring frequent or rapid writes. Restriction of hazardous substances (RoHS) compliant Examples range from data logging, where the number of write cycles may be critical, to demanding industrial controls where the long write time of EEPROM can cause data loss. The combination of features allows more frequent data writing with less overhead for the system. The CY15E016J provides substantial benefits to users of serial 2 (I C) EEPROM as a hardware drop-in replacement. The device specifications are guaranteed over an automotive-a temperature range of 40 C to +85 C.
