Alliance Memory AS29CF160x-55TIN Parallel NOR Flash Memories

Alliance Memory AS29CF160x-55TIN Parallel NOR Flash Memories are organized as 2,097,152 bytes of 8 bits or 1,048,576 words of 16 bits each. These memories use pins I/O0 to I/O7 for 8-bit data and pins I/O0 to I/O15 for 16-bit data. The AS29CF160x-55TIN Flash memories are available in 48-pin TSOP packages. These memories are designed to be programmed in-system with the standard system 5V VCC supply. The AS29CF160x-55TIN memories require only a single 5V power supply for both read and write functions. The program and erase functions use internally generated and regulated voltages.

The AS29CF160x-55TIN Flash memories are entirely software command set compatible with the JEDEC single power supply flash standard. These memories feature sector-erase architecture that allows memory sectors to be erased and reprogrammed without affecting the data contents of the device. The power-saving features allow the device to be placed in standby mode with greatly reduced power consumption.

  • Unlock bypass program command
    • Reduces overall programming time when issuing multiple program command sequence
  • Top or bottom boot block configurations available
  • Embedded algorithms
    • Embedded Erase algorithm will automatically erase the entire chip or any combination of designated sectors and verify the erased sectors
    • Embedded Program algorithm automatically writes and verifies data at specified addresses
  • Minimum 100,000 program/erase cycles per sector
  • 20-year data retention at 125ºC
    • Reliable operation for the life of the system
  • CFI (Common Flash Interface) compliant
    • Provides device-specific information to the system, allowing host software to reconfigure for different Flash devices easily
  • Compatible with JEDEC standards
    • Pinout and software compatible with single-power-supply Flash memory standard
    • Superior inadvertent write protection
  • Data Polling and toggle bits
    • Provides a software method of detecting the completion of a program or erasing operations
  • Ready/BUSY pin (RY/BY)
    • Provides a hardware method of detecting the completion of a program or erasing operations
  • Erase Suspend/Erase Resume
    • Suspends a sector erase operation to read data from, or program data to, a non-erasing sector, then resumes the erase operation
  • Hardware reset pin (RESET)
    • Hardware method to reset the device to reading array data
  • WP input pin (48 pins TSOP)
    • At VIL, protects the 16Kbyte boot sector from erasure regardless of sector protect/unprotect status
    • At VIH, allows the removal of boot sector protection
  • Package options
    • 48-pin TSOP (I)
    • All Pb-free (Lead-free) products are RoHS2.0 compliant
