|Part No||32MX16 ONE-NAND|
|Std. Pack Qty||1600|
OneNAND™‚ is a monolithic integrated circuit with a NAND Flash array using a NOR Flash interface. This device
includes control logic, a NAND Flash array, and 5KB of internal BufferRAM. The BufferRAM reserves 1KB for boot
code buffering (BootRAM) and 4KB for data buffering (DataRAM), split between 2 independent buffers. It has a x16
Host Interface and a random access time speed of ~76ns.
The device operates up to a maximum host-driven clock frequency of 66MHz for synchronous reads at Vcc(or Vccq.
Refer to chapter 4.2) with minimum 6-clock latency. Below 40MHz it is accessible with minimum 3-clock latency.
Appropriate wait cycles are determined by programmable read latency.
OneNAND provides for multiple sector read operations by assigning the number of sectors to be read in the sector
counter register. The device includes one block-sized OTP (One Time Programmable) area and user-controlled 1st block
OTP(Block 0) that can be used to increase system security or to provide identification capabilities.
