CY15E004Q

4-Kbit (512 × 8) Serial (SPI) Automotive-A

F-RAM

4-Kbit (512

× 8) Serial (SPI) Automotive-A F-RAM

Features

Functional Description

■ 4-Kbit ferroelectric random access memory (F-RAM) logically

organized as 512 × 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 CY15E004Q is a 4-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 CY15E004Q 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 CY15E004Q is capable of supporting

10¹⁴read/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 CY15E004Q 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

❐ 250 A active current at 1 MHz

❐ 4 A (typ) standby current

■ Voltage operation: V_DD= 4.5 V to 5.5 V

■ Automotive-A temperature: –40 C to +85 C

■ 8-pin small outline integrated circuit (SOIC) package

■ Restriction of hazardous substances (RoHS) compliant

The CY15E004Q provides substantial benefits to users of serial

EEPROM or flash as a hardware drop-in replacement. The

CY15E004Q 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.

Errata: The Write Enable Latch (WEL) bit in the Status Register of CY15E004Q part does not clear after executing the memory write (WRITE) operation at memory

location(s) from 0x100 to 0x1FF. For more information, see Errata on page 19. Details include errata trigger conditions, scope of impact, available workarounds, and

silicon revision applicability.
