Cypress’s EZ-USB® FX2LP (CY7C68013A/14A) is a low
power version of the EZ-USB FX2(CY7C68013), which is a
highly integrated, low power USB 2.0 microcontroller. By
integrating the USB 2.0 transceiver, serial interface engine (SIE),
enhanced 8051 microcontroller, and a programmable peripheral
interface in a single chip,
than USB 2.0 SIE or external transceiver implementations. With
EZ-USB FX2LP, the Cypress Smart SIE handles most of the
USB 1.1 and 2.0 protocol in hardware, freeing the embedded
microcontroller for application specific functions and decreasing
development time to ensure USB compatibility.
The General Programmable Interface (GPIF) and Master/Slave
Endpoint FIFO (8-bit or 16-bit data bus) provides an easy and
glueless interface to popular interfaces such as ATA, UTOPIA,
EPP, PCMCIA, and most DSP/processors.
Cypress has created a cost effective solution that provides
superior time-to-market advantages with low power to enable
bus powered applications.
The ingenious architecture of FX2LP results in data transfer
rates of over 53 Mbytes per second, the maximum allowable
USB 2.0 bandwidth, while still using a low cost 8051
The FX2LP draws less current than the FX2 (CY7C68013), has
double the on-chip code/data RAM, and is fit, form and function
compatible with the 56, 100, and 128 pin FX2.
microcontroller in a package as small as a 56 VFBGA (5 mm x 5
mm). Because it incorporates the USB 2.0 transceiver, the
FX2LP is more economical, providing a smaller footprint solution
Five packages are defined for the family: 56 VFBGA, 56 SSOP,
56 QFN, 100 TQFP, and 128 TQFP.
