Functional Description
EZ-USB FX1
(CY7C64713/4) is a full-speed highly
integrated, USB microcontroller. By integrating the USB trans-
ceiver, serial interface engine (SIE), enhanced 8051 microcon-
troller, and a programmable peripheral interface in a single
chip, Cypress has created a very cost-effective solution that
provides superior time-to-market advantages.
Because it incorporates the USB transceiver, the EZ-USB FX1
is more economical, providing a smaller footprint solution than
USB SIE or external transceiver implementations. With
EZ-USB FX1, the Cypress Smart SIE handles most of the USB
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- or 16-bit data bus) provides an easy
and glueless interface to popular interfaces such as
ATA,
UTOPIA, EPP, PCMCIA, and most DSP/processors.
Three lead-free packages are defined for the family: 56 QFN,
100 TQFP, and 128
TQFP.

Functional Overview
4.1
FX1 operates at one of the three rates defined in the USB
Specification Revision 2.0, dated April 27, 2000:
Full speed, with a signaling bit rate of 12 Mbps.
FX1 does not support the low-speed signaling mode of 1.5
Mbps or the high-speed mode of 480 Mbps.
USB Signaling Speed
4.2
The 8051 microprocessor embedded in the FX1 family has
256 bytes of register RAM, an expanded interrupt system,
three timer/counters, and two USARTs.
8051 Microprocessor
4.2.1
FX1 has an on-chip oscillator circuit that uses an external 24-
MHz (±100 ppm) crystal with the following characteristics:
Parallel resonant
Fundamental mode
500-
μ
W drive level
12-pF (5% tolerance) load capacitors.
An on-chip PLL multiplies the 24-MHz oscillator up to 480
MHz, as required by the transceiver/PHY, and internal
counters divide it down for use as the 8051 clock. The default
8051 clock frequency is 12 MHz. The clock frequency of the
8051 can be changed by the 8051 through the CPUCS
register, dynamically.
The CLKOUT pin, which can be three-stated and inverted
using internal control bits, outputs the 50% duty cycle 8051
clock, at the selected 8051 clock frequency—48, 24, or 12
MHz.
8051 Clock Frequency
4.2.2
FX1 contains two standard 8051 USARTs, addressed via
Special Function Register (SFR) bits. The USART interface
pins are available on separate I/O pins, and are not multi-
plexed with port pins.
UART0 and UART1 can operate using an internal clock at 230
KBaud with no more than 1% baud rate error. 230-KBaud
operation is achieved by an internally derived clock source that
generates overflow pulses at the appropriate time. The
internal clock adjusts for the 8051 clock rate (48, 24, 12 MHz)
such that it always presents the correct frequency for 230-
KBaud operation.

USARTS
4.2.3
Certain 8051 SFR addresses are populated to provide fast
access to critical FX1 functions. These SFR additions are
shown in
Table 4-1
. Bold type indicates non-standard,
enhanced 8051 registers. The two SFR rows that end with “0”
and “8” contain bit-addressable registers. The four I/O ports
A–D use the SFR addresses used in the standard 8051 for
ports 0–3, which are not implemented in FX1. Because of the
faster and more efficient SFR addressing, the FX1 I/O ports
are not addressable in external RAM space (using the MOVX
instruction).

115-KBaud operation is also possible by programming the 8051 SMOD0 or SMOD1 bits to a “1” for UART0 and/or UART1, respectively.
