CYWT16B512
512 Mb (64 MB), 3.0 V Serial NOR Flash
Memory
Wide temperature range
General description
The CY16B family devices are Flash non-volatile memory products using:
• Floating Gate technology
• 65 nm process lithography
The CY16B family connects to a host system via a serial peripheral interface (SPI). Traditional SPI serial input and
output (IO1 and IO5) is supported and eight bit wide quad I/O (QIO) and quad peripheral interface (QPI)
commands. In addition, there are double data rate (DDR) read commands for QIO and QPI that transfer address
and read data on both edges of the clock.
The architecture features a Page Programming Buffer that allows up to 512-bytes to be programmed in one
operation and provides individual 8 KB sector, 64 KB half block, 128 KB block, or entire chip erase.
By using CY16B family devices at the higher clock rates supported, with Quad commands, the instruction read
transfer rate can match or exceed traditional parallel interface, asynchronous, NOR Flash memories, while
reducing signal count dramatically.
The CY16B family products offer high densities coupled with the flexibility and fast performance required by a
variety of mobile or embedded applications. Provides an ideal storage solution for systems with limited space,
signal connections, and power. These memories offer flexibility and performance well beyond ordinary serial
flash devices. They are ideal for code shadowing to RAM, executing code directly (XIP), and storing
re-programmable data.
