Overview
Cypress Semiconductor Corporation’s EZ-USB
(CY7C68033/CY7C68034) is a firmware-based, programmable
version of the EZ-USB NX2LP (CY7C68023/CY7C68024),
which is a fixed-function, low power USB 2.0 NAND Flash
controller. By integrating the USB 2.0 transceiver, serial interface
engine (SIE), enhanced 8051 microcontroller, and a program-
mable peripheral interface in a single chip, Cypress has created
a very cost-effective solution that enables feature-rich NAND
Flash-based applications.
The ingenious architecture of NX2LP-Flex results in USB data
transfer rates of over 53 Mbytes per second, the maximum
allowable USB 2.0 bandwidth, while still using a low cost 8051
microcontroller in a small 56-pin QFN package. Because it incor-
porates the USB 2.0 transceiver, the NX2LP-Flex is more
economical, providing a smaller footprint solution than external
USB 2.0 SIE or transceiver implementations. With EZ-USB
NX2LP-Flex, the Cypress Smart SIE handles most of the USB
1.1 and 2.0 protocol, freeing the embedded microcontroller for
application-specific functions and decreasing development time
while ensuring USB compatibility.
The GPIF and master/slave endpoint FIFO (8- or 16-bit data bus)
provide an easy and glueless interface to popular interfaces such
as UTOPIA, EPP, I
Applications
