CY7C64713 Functional Description FX1 does not support the low speed signaling mode of 1.5 Mbps or the high speed mode of 480 Mbps. EZ-USB FX1 (CY7C64713) is a full speed, highly integrated, USB microcontroller. By integrating the USB transceiver, Serial 8051 Microprocessor Interface Engine (SIE), enhanced 8051 microcontroller, and a The 8051 microprocessor embedded in the FX1 family has programmable peripheral interface in a single chip, Cypress has 256bytes of register RAM, an expanded interrupt system, three created a very cost effective solution that provides superior timer/counters, and two USARTs. time-to-market advantages. The EZ-USB FX1 is more economical, because it incorporates 8051 Clock Frequency the USB transceiver and provides a smaller footprint solution FX1 has an on-chip oscillator circuit that uses an external than the USB SIE or external transceiver implementations.

Because of the faster and Full speed, with a signaling bit rate of 12 Mbps. more efficient SFR addressing, the FX1 I/O ports are not addressable in the external RAM space (using the MOVX instruction).

FX1 provides a second level of interrupt vectoring, called Autovectoring, to save code and processing time that is normally When first plugged into the USB, the FX1 enumerates required to identify the individual USB interrupt source. When a automatically and downloads firmware and the USB descriptor USB interrupt is asserted, the FX1 pushes the program counter tables over the USB cable. Next, the FX1 enumerates again, this on to its stack and then jumps to address 0x0043, where it time as a device defined by the downloaded information. This expects to find a “jump” instruction to the USB Interrupt service patented two step process, called ReNumeration, happens routine. instantly when the device is plugged in, with no indication that the initial download step has occurred.

The GPIF is a flexible 8 or 16-bit parallel interface driven by a In Master (M) mode, the GPIF internally controls FIFOADR[1..0] user programmable finite state machine. It allows the to select a FIFO. The RDY pins (two in the 56-pin package, six CY7C64713 to perform local bus mastering, and can implement in the 100-pin and 128-pin packages) are used as flag inputs a wide variety of protocols such as ATA interface, printer parallel from an external FIFO or other logic if desired. The GPIF is run port, and Utopia. from either an internally derived clock or an externally supplied The GPIF has six programmable control outputs (CTL), nine clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s address outputs (GPIFADRx), and six general purpose Ready (48 MHz IFCLK with 16-bit interface). inputs (RDY). The data bus width is 8 or 16 bits. Each GPIF In Slave (S) mode, the FX1 accepts either an internally derived vector defines the state of the control outputs, and determines clock or an externally supplied clock (IFCLK with a maximum what state a Ready input (or multiple inputs) must be before frequency of 48 MHz) and SLCS#, SLRD, SLWR, SLOE, proceeding.

Therefore, using it meets the control bit is set to pulse the RD# and WR# pins when the 8051 set up time to the next read. reads from or writes to the PORTC.

X is the value t and the hold time t for PKTEND must be met. the AUTOINLEN register is set to when the IN endpoint is SPE PEH configured to be in auto mode. Although there are no specific timing requirements for asserting PKTEND in relation to SLWR, there exists a specific case Figure24 shows a scenario where two packets are being condition that needs attention. When using the PKTEND to committed. The first packet is committed automatically when the commit a one byte or word packet, an additional timing number of bytes in the FIFO reaches X (value set in AUTOINLEN requirement must be met when the FIFO is configured to operate register) and the second one byte or word short packet being in auto mode and it is necessary to send two packets back to committed manually using PKTEND. Note that there is at least back: one IFCLK cycle timing between asserting PKTEND and clocking of the last byte of the previous packet (causing the ■A full packet (defined as the number of bytes in the FIFO packet to be committed automatically). Failing to adhere to this meeting the level set in the AUTOINLEN register) committed timing results in the FX2 failing to send the one byte or word short automatically followed by packet. ■A short one byte or word packet committed manually using the PKTEND pin.

Items Part Number Silicon Revision Fix Status [1]. Empty Flag Assertion CY7C64713/4 B No silicon fix planned currently. Use workaround 1.Empty Flag Assertion ■Problem Definition When Configured in Slave FIFO Asynchronous Word Wide mode and if only single word data transferred from USB Host to EP2 configured as OUT End Point (EP) in the very first transaction then Empty flag behaves incorrectly. This does not happened if data size is more than a word length in the first transaction. ■Parameters Affected NA ■Trigger Condition(S) In Slave FIFO Word Wide Mode, after firmware boot and initialization, EP2 OUT Endpoint empty flag indicates status as Empty. Upon data reception in EP2 it changes to Not-Empty. But if data transferred to EP2 is single word only, then asserting SLRD with FIFOADR pointing to any other Endpoint, changes Not-Empty status to Empty for EP2 even though a word data is there (or it is untouched) in EP2. This is noticed only when the single word is sent as the very first transaction and does not happen if it follows multi-word packet as the first transaction. ■Scope of Impact External interface does not see data available in EP2 OUT Endpoint and might end up waiting for data to be read. ■Workaround Any one of the following workaround can be used i.Give out Pulse signal to the SLWR pin, with FIFOADR pins pointing to an Endpoint other than EP2, after firmware initialization and before/after transferring the data to EP2 from Host, or ii.Set length of very first data to EP2 to be more than a word, or iii.Prioritize EP2 read from Master in case of multiple OUT EPs and single word write to EP2, or iv.Write to any IN EP, if any, from Master before reading from other OUT EPs (other than EP2) from Master. ■Fix Status There is no silicon fix planned for this currently, you can use above workaround.
