The CY15B128Q-SXAT is a 128-Kbit automotive-grade serial F-RAM memory, organized as 16K × 8 and accessed via SPI up to 40 MHz. It delivers 100 trillion (10^14) read/write cycles and 151-year data retention at 65°C. Operating from 2.0 V to 3.6 V, it features low power consumption—2.5 mA active, 150 μA standby, and 8 μA sleep mode. Hardware and software write protection make it ideal for frequent, rapid-write applications in automotive and industrial environments.

Features

  • 128-Kbit ferroelectric RAM (F-RAM)
  • 100 trillion (10^14) read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ instant write technology
  • SPI interface up to 40 MHz
  • Supports SPI mode 0 and mode 3
  • Hardware write protection (WP pin)
  • Software write protection and block protect
  • 2.5 mA active, 150 μA standby, 8 μA sleep
  • VDD operation from 2.0 V to 3.6 V
  • Device ID with Manufacturer and Product ID

Benefits

  • Enables frequent, reliable data logging
  • Prevents data loss from power interruption
  • Eliminates write delays for fast operation
  • Drop-in replacement for serial flash/EEPROM
  • Reduces system power consumption
  • Flexible integration with SPI bus
  • Protects data from accidental writes
  • Simplifies system-level data security
  • Supports low-voltage designs
  • Identifies device for inventory tracking
