CY15V104QSN集成電路（IC）的存儲器規(guī)格書PDF中文資料

Features

? 4-Mbit ferroelectric random access memory (F-RAM) logically organized as 512K × 8

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

- 151-year data retention (see Data retention and endurance on page 98)

- Infineon instant non-volatile write technology

- 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 54-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 1-bit error. If a 2-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

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

- 16 mA (typ) active current for 108 MHz QSPI SDR and 54-MHz QSPI DDR

- 110 μA (typ) standby current

- 0.80 μA (typ) deep power down mode current

- 0.1 μA (typ) hibernate mode current

? Low-voltage operation:

- CY15V104QSN: VDD = 1.71 V to 1.89 V

- CY15B104QSN: VDD = 1.8 V to 3.6 V
