cy7c6461 3 document #: 38-08005 rev. *b page 6 of 42 1.3 other resources other sources of ez-usb fx information include: ez-usb fx technical reference manual (trm), version 1.2 or higher cy3671 ez-usb fx development kit the web site www.cypress.com, which includes information about many reference designs, such as usb mass storage device, adsl modem, mpeg.2 players, etc. 2.0 functional overview 2.1 microprocessor the cy7c64613 uses a 12-mhz crystal for low emi. an internal oscillator and pll develops an internal 48-mhz clock for use by the usb serial interface engine and the 8051 microprocessor. the 8051 can run at either 24 mhz or 48 mhz, controlled by a bit in the eeprom attached to the i 2 c-compatible bus. the default rate (with no eeprom connected) is 24 mhz. the internal microprocessor is an enhanced version of the industry-standard 8051. enhancements include four clocks per instruction cycle operation, a second data pointer, and an enhanced interrupt system. the 8051 includes two uarts, three counter-timers, and 256 bytes of register ram. the ez-usb family implements i/o differently than the standard 8051 by having its i/o control registers in external memory spac e. the cy7c64613 preserves this addressing for backward ez-usb compatibility, and adds the ability to control i/o registers using 8051 special function registers (sfrs). this improves i/o access time. for example, an i/o pin may be toggled using one 8051 instruction, e.g., cpl (bit). the 8051 code and xdata memory consists of an internal 8 kb ram. this ram is normally downloaded via the usb cable at plug-in, followed by the 8051 starting up and executing the downloaded code. this gives the cy7c64613 family its ?soft? operati on feature, whereby permanent memory such as rom or flash memory is not required. program code updates can easily be done in the field since the code is loaded from the pc, not by physically changing or reprogramming a memory device. the 8051 program memory can also be loaded from the eeprom connected to the i 2 c compatible bus on reset for stand-alone use without the usb connected. the 128-pin version of the cy7c64613 brings out the full 8051 address and data buses, plus decoded control signals oe#, cs#, rd#, psen#, and wr# to allow glueless connection to external memory devices. the 80- and 52-pin packages allow smaller footprints and more cost effective solutions for certain designs, but do not have external access to the 8051 buses. 2.2 usb sie the cy7c64613 uses the ez-usb family enhanced sie (serial interface engine). this sie has the intelligence to perform full usb enumeration, creating a default usb device with predefined endpoints and alternate settings. this enhanced sie is essential in achieving the family?s soft operation, since it provides the mechanism to download firmware prior to the 8051 running. once the 8051 is in control, it can use advanced features of the sie to simplify its usb firmware. endpoint zero setup data is placed in a separate 8-byte ram space for easy access. get_descriptor requests are simplified by using a special setup data pointer. the 8051 simply loads a descriptor address into this 16-bit register, and the sie takes care of the remaining overhead, i.e., dividing the descriptor into packets, sending them via endpoint 0 in response to in tokens, and providing the necessary handshakes. the 8051 can do other chores while the sie completes this usb transfer. 2.3 gpif (general programmable interface) the gpif is a flexible 8- or 16-bit parallel interface driven by a user-programmable set of vectors that operate similarly to a finite state machine. it allows the cy7c64613 to perform local bus mastering, and can implement a wide variety of protocols such as atapi, printer parallel port, pcmcia and utopia. the gpif has six programmable control outputs (ctl), six address outputs (adr), and six general purpose ready inputs (rdy). the data bus width can be 8 or 16 bits. each gpif instruction defines the state of the control outputs, or determines wh at state a ready input (or multiple inputs) must be before proceeding. a sequence of the gpif instructions make up a single wavefo rm that will be executed to perform the desired data move between the cy7c64613 and the external circuit. 2.4 slave fifos many high-bandwidth usb designs use a fifo between the usb interface chip and external logic to match data rates, or to smooth the usb data delivery (which, being packet oriented, occurs in bursts). the cy7c64613 moves this glue logic into the part by providing four 64-byte internal slave fifos. the fifos also provide two important interface functions, external clockin g and bus width conversion. using external clocking, external logic (such as a dsp or asic) can clock data into or out of the slave fifos under control of its own clock, rather than synchronizing with the clock supplied by the cy7c64613 (24 or 48 mhz). the externally supplied clock
cy7c6461 3 document #: 38-08005 rev. *b page 7 of 42 must be free running. the fifos can be controlled either synchronously (using strobe signals and a clock) or asynchronously (using strobe signals only). the slave fifo data is available as two 8-bit buses, which may be used simultaneously to operate as a single 16-bit data bus. the 16-bit connection, along with fast double-byte mode, combine to give fast conversion between 8- and 16-bit buses. a flexible set of fifo flags (full, empty, and programmable) provide fifo flow control. 2.5 dma with many sources and destinations for usb data, such as endpoint buffers, slave fifos, and internal/external ram buffers, it is important to move blocks of data between them quickly. using internal dma, the 8051 sets up source, destination, and transfe r length registers, and then initiates a dma transfer. the maximum dma transfer rate occurs between internal resources, such as endpoint buffers and slave fifos. this maximum rate is one byte per 48-mhz clock, or 48 mbytes per second. 2.6 flexible configuration the ez-usb fx supports a highly configurable i/o structure. figure 2-1 on page 8 shows the general scheme of the assignment of pins to i/o ports. the 80- and 56-pin products are subsets of the 128-pin products, hence they follow a similar scheme. for details of how to set the configuration registers to configure the i/o ports, consult ?cy7c64613 pin descriptions? on page 14 of this data sheet and the ez-usb fx trm.

cy7c6461 3 document #: 38-08005 rev. *b page 14 of 42 3.2 general notes about the pin description table 1. see the ez-usb fx trm : for multiplexed pins, consult the ez-usb fx trm (primarily chapter 4) for details of setting the configuration registers. 2. multiple routed signals : in some cases, an internal signal can be routed to more than one pin. for example, in the 80 and 128-pin packages rdy4 can be routed to any combination of (neither, either or both) pins 15 and 26. 3. tie up unused inputs : it is important that the recommendations in the pin description table be followed, especially for inputs. unused cmos inputs can oscillate if they are left open (floating), which can cause higher power usage and decreased reliability. 4. tie up certain outputs that are initially inputs : many alternate functions of the fx multiplexed pins are similar to the wr# alternate functions (see the pc6 / wr# / ctl4 pin below) in the following respect: if wr# is chosen as the function of pc6, it should be pulled up to vcc through a pull-up resistor . this is to ensure that wr# is inactive (pulled high) at power-up, since, before the 8051 can configure this pin to wr#, it defaults to ?pc6 an input? (not driven by the fx pin). all multiplexed pins that you use should be carefully considered in your circuit design for the effects of the transition throu gh their default configuration at power-up. these are typically (though not always) active low signals such as wr#. the critical time interval to be considered is between reset# deasserted and the pin driven as an output (immediately after the 8051 code has initialized the port to be an alternate function that it is an output). 3.3 cy7c64613 pin descriptions 128 80 52 name type default description 18 5 5 avcc power n/a analog v cc . this signal provides power to the analog section of the chip. 21 8 8 agnd power n/a analog ground . connect to ground with as short a path as possible. 48 28 18 discon# o/z h disconnect . this pin can drive high, low, or float. discon# pin floats when the register bit usbcs.2 is low, and drives when it is high. the drive level of the discon# pin is the invert of register bit usbcs.3. the discon# pin is normally connected to the usb d+ line through a 1500 ? resistor. the cy7c64613 signals a usb connection by setting usbcs.3=0 (drive 3.3v) and usbcs.2=1 (output enable). the cy7c64613 signals a usb disconnect by setting usbcs.2=0 which floats the pin and disconnects the 1500 ? resistor from d+. 65 38 24 usbd? i/o/z z usb d? connect to the usb d? signal through a 22 5% ohm resistor. 66 39 25 usbd+ i/o/z z usb d+ connect to the usb d+ signal through a 22 5% ohm resistor. 105 a0 output l 8051 address bus . this bus is driven at all times. when the 8051 is addressing internal ram it reflects the internal address. during dma transfers that use the rd# and wr# strobes, the address bus contains the incrementing dma source or destination address for data trans- ferred over d[7.0]. 106 a1 output l 107 a2 output l 108 a3 output l 114 a4 output l 115 a5 output l 116 a6 output l 117 a7 output l 118 a8 output l 120 a9 output l 121 a10 output l 122 a11 output l 127 a12 output l 128 a13 output l 1a14outputl 2a15outputl

(normally used to boot from external memory, for example, boot from flash). this pin is ?live?. see psen# pin.

(note: the gpif always uses a 48-mhz clock or xclk, regardless of the 8051 clock. see xclk and xclksel.) the frequency of the 8051 clock is set via a boot eeprom bit: if config 0.2 = 0, clkout is 24 mhz. if config 0.2 = 1, clkout is 48 mhz. clkout may be inverted by se tting a boot eeprom bit config0.1 = 1. if no eeprom is connected to the i 2 c compatible port (the required pull-up resistors must be present), the config0 bits default to zero, hence ? clkout is 24 mhz ? clkout is non-inverted. the 8051 may three-state this output by setting cpucs.1 = 1. port a 25 11 pa0 or t0out i/o/z i (pa0) multiplexed pin whose function is selected by two bits: portacfg.0 and ifconfig.3. pa0 is a bidirectional io port pin. t0out is an active-high signal from 8051 timer-counter0. t0out outputs a high level for one clkout clock cycle when timer0 overflows. if timer0 is operated in mode 3 (two separate timer/counters), t0out is active when the low byte timer/counter overflows. 26 12 pa1 or t1out i/o/z i (pa1) multiplexed pin whose function is selected by two bits: portacfg.1 and ifconfig.3. pa1 is a bidirectional io port pin. t1out is an active-high signal from 8051 timer-counter1. t1out outputs a high level for one clkout clock cycle when timer1 overflows. if timer1 is operated in mode 3 (two separate timer/counters), t1out is active when the low byte timer/counter overflows. 27 13 pa2 or oe# or i/o/z i (pa2) multiplexed pin whose function is selected by two bits: portacfg.2 and ifconfig.3. pa2 is a bidirectional io port pin. oe# is an active-low output enable for external memory. if the oe# function is chosen for this pin, it should be externally pulled up to v cc through a pull-up resistor. this is to ensure that oe# is inactive (pulled high) at power up, since, before the 8051 can configure this pin to oe#, it defaults to ?pa2 an input? 28 14 pa3 or cs# i/o/z i (pa3) multiplexed pin whose function is selected by the portacfg.3 bit. pa3 is a bidirectional i/o port pin. cs# is an active-low chip select for external memory. if the cs# function is chosen for this pin, it should be externally pulled up to v cc . this is to ensure that cs# is inactive (pulled high) at power up, since, before the 8051 can configure this pin to cs#, it defaults to ?pa3 an input?. 29 15 10 pa4 or fwr# or rdy4 or slwr i/o/z i (pa4) multiplexed pin whose function is selected by the following bits: portacfg.4, portacf2.4, and ifconfig[1..0]. pa4 is a bidirectional i/o port pin. fwr# is the write strobe output for an external fifo connected to the data bus d[7..0]. rdy4 is a gpif input signal. rdy4 is a gpif input signal. slwr is the write strobe input for the slave fifos connected to afi[7..0] and/or bfi[7..0]. if the fwr# pin is used, it should be externally pulled up to v cc. this is to ensure that fwr# is inactive (pulled high) at power up, since, before the 8051 can configure this pin to fwr#, it defaults to ?pa4 an input?. 3.3 cy7c64613 pin descriptions (continued) 128 80 52 name type default description
