Features

• 16-Mb ferroelectric random access memory (F-RAM) logically organized as 2048K x 8

- Virtually unlimited endurance of 100 trillion (1014) read/write cycles

- 151-year data retention (See “Data retention and endurance” on page 88)

- Infineon no delay technology writes

- Advanced high-reliability ferroelectric process

• Single and multi I/O serial peripheral interface (SPI)

- Serial bus interface SPI protocols

- Supports SPI mode 0 (0, 0) and mode 3 (1, 1) for all SDR mode transfers

- Supports SPI mode 0 (0, 0) for all DDR mode transfers

- Extended I/O SPI protocols

- Dual SPI (DPI) protocols

- Quad SPI (QPI) protocols

• SPI clock frequency

- Up to 108 MHz frequency SPI single data rate (SDR)

- Up to 46 MHz frequency SPI double data rate (DDR)

• Execute-in-place (XIP) for memory read/write

• Write protection, data security, and data integrity

• Hardware protection using the write protect (WP) pin

• Software block protection

• Embedded error correction code (ECC) and cyclic redundancy check (CRC) for enhanced data integrity

- ECC detects and corrects 2-bit error. If a 3-bit error occurs, it does not correct but reports through the ECC

status register

- CRC detects any accidental change to raw data

• Extended electronic signatures

- Device ID includes manufacturer ID and product ID

- Unique ID

- User programmable serial number

• Dedicated 256-byte special sector F-RAM

- Dedicated special sector write and read

- Content can survive up to three standard reflow cycles

• Low-power consumption at high speed

- 14 mA (typ) active current for 108 MHz SPI SDR

- 22 mA (typ) active current for 108 MHz QSPI SDR

- 16.5 mA (typ) active current for 46 MHz QSPI DDR

- 115 μA (typ) standby current

- 1.1 μA (typ) deep power-down mode current

- 0.1 μA (typ) Hibernate mode current

• Low-voltage operation:

- CY15V116QSN: VDD = 1.71 V to 1.89 V

- CY15B116QSN: VDD = 1.8 V to 3.6 V

• Operating temperature: –40°C to +85°C
