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

- 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
