By integrating the USB 2.0 transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very 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 microcontroller in a package as small as a 56 VFBGA (5mm x 5mm). Because it incorporates the USB 2.0 transceiver, the FX2LP is more economical, providing a smaller footprint solution than USB 2.0 SIE or external transceiver implementations. With Document #: 38-08032 Rev. *K 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- or 16-bit data bus) provides an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors. The FX2LP draws considerably 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. Five packages are defined for the family: 56VFBGA, 56 SSOP, 56 QFN, 100 TQFP, and 128 TQFP. 2.0 Applications • Portable video recorder • MPEG/TV conversion • DSL modems • ATA interface • Memory card readers • Legacy conversion devices • Cameras • Scanners • Home PNA • Wireless LAN • MP3 players • Networking The “Reference Designs” section of the Cypress web site provides additional tools for typical USB 2.0 applications. Each reference design comes complete with firmware source and object code, schematics, and documentation. Please visit http://www.cypress.com for more information.

FX2LP does not support the low-speed signaling mode of 1.5 Mbps. 3.2 8051 Microprocessor The 8051 microprocessor embedded in the FX2LP family has 256 bytes of register RAM, an expanded interrupt system, three timer/counters, and two USARTs. 3.2.1 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. 3.2.2 USARTS FX2LP 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 multiplexed 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.[1] 8051 Clock Frequency FX2LP has an on-chip oscillator circuit that uses an external 24-MHz (±100-ppm) crystal with the following characteristics: • Parallel resonant • Fundamental mode • 500-µW 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. C1 24 MHz 12 pf C2 12 pf 3.2.3 Certain 8051 SFR addresses are populated to provide fast access to critical FX2LP functions. These SFR additions are shown in Table 3-1. 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 FX2LP. Because of the faster and more efficient SFR addressing, the FX2LP I/O ports are not addressable in external RAM space (using the MOVX instruction). 3.3 I2C Bus FX2LP supports the I2C bus as a master only at 100-/400-KHz. SCL and SDA pins have open-drain outputs and hysteresis inputs. These signals must be pulled up to 3.3V, even if no I2C device is connected. 3.4 20 × PLL Special Function Registers Buses All packages: 8- or 16-bit “FIFO” bidirectional data bus, multiplexed on I/O ports B and D. 128-pin package: adds 16-bit output-only 8051 address bus, 8-bit bidirectional data bus. 12-pF capacitor values assumes a trace capacitance of 3 pF per side on a four-layer FR4 PCA Figure 3-1. Crystal Configuration Note: 1. 115-KBaud operation is also possible by programming the 8051 SMOD0 or SMOD1 bits to a “1” for UART0 and/or UART1, respectively.

If found, it uses the VID/PID/DID values in the EEPROM in place of the internally stored values (0xC0), or it boot-loads the EEPROM contents into internal RAM (0xC2). If no EEPROM is detected, FX2LP enumerates using internally stored descriptors. The default ID values for FX2LP are VID/PID/DID (0x04B4, 0x8613, 0xAxxx where xxx = Chip revision).[2] Table 3-2. Default ID Values for FX2LP Vendor ID Product ID Device release 3.6 Default VID/PID/DID 0x04B4 Cypress Semiconductor 0x8613 EZ-USB FX2LP 0xAnnn Depends on chip revision (nnn = chip revision where first silicon = 001) ReNumeration™ GPIFSGLDATH GPIFSGLDATLX GPIFSGLDATLNOX RENUM. To simulate a USB disconnect, the firmware sets DISCON to 1. To reconnect, the firmware clears DISCON to 0. Before reconnecting, the firmware sets or clears the RENUM bit to indicate whether the firmware or the Default USB Device will handle device requests over endpoint zero: if RENUM = 0, the Default USB Device will handle device requests; if RENUM = 1, the firmware will. 3.7 Bus-powered Applications The FX2LP fully supports bus-powered designs by enumerating with less than 100 mA as required by the USB 2.0 specification. 3.8 Interrupt System 3.8.1 INT2 Interrupt Request and Enable Registers FX2LP implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors. See EZ-USB Technical Reference Manual (TRM) for more details. Because the FX2LP’s configuration is soft, one chip can take on the identities of multiple distinct USB devices. 3.8.2 When first plugged into USB, the FX2LP enumerates automatically and downloads firmware and USB descriptor tables over the USB cable. Next, the FX2LP enumerates again, this time as a device defined by the downloaded information. This patented two-step process, called ReNumeration™, happens instantly when the device is plugged in, with no hint that the initial download step has occurred. The main USB interrupt is shared by 27 interrupt sources. To save the code and processing time that normally would be required to identify the individual USB interrupt source, the FX2LP provides a second level of interrupt vectoring, called Autovectoring. When a USB interrupt is asserted, the FX2LP pushes the program counter onto its stack then jumps to address 0x0043, where it expects to find a “jump” instruction to the USB Interrupt service routine. Two control bits in the USBCS (USB Control and Status) register control the ReNumeration process: DISCON and USB-Interrupt Autovectors Note: 2. The I2C bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this detection method does not work properly.

Document #: 38-08032 Rev. *K 3.8.3 FIFO/GPIF Interrupt (INT4) Just as the USB Interrupt is shared among 27 individual USB-interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual FIFO/GPIF sources.

When the ISR occurs, the FX2LP pushes the program counter onto its stack then jumps to address 0x0053, where it expects to find a “jump” instruction to the ISR Interrupt service routine. used with the CY7C680xxA the reset period must allow for the stabilization of the crystal and the PLL. This reset period should be approximately 5 ms after VCC has reached 3.0V. If the crystal input pin is driven by a clock signal the internal PLL stabilizes in 200 µs after VCC has reached 3.0V[3]. Figure 3-2 shows a power-on reset condition and a reset applied during operation. A power-on reset is defined as the time reset is asserted while power is being applied to the circuit. A powered reset is defined to be when the FX2LP has previously been powered on and operating and the RESET# pin is asserted. 3.9 Reset and Wakeup 3.9.1 Reset Pin Cypress provides an application note which describes and recommends power on reset implementation and can be found on the Cypress web site. For more information on reset implementation for the FX2 family of products visit the http://www.cypress.com. The input pin, RESET#, will reset the FX2LP when asserted. This pin has hysteresis and is active LOW. When a crystal is Note: 3. If the external clock is powered at the same time as the CY7C680xxA and has a stabilization wait period, it must be added to the 200 µs.

This stops the oscillator and PLL. When WAKEUP is asserted by external logic, the oscillator restarts, after the PLL stabilizes, and then the 8051 receives a wakeup interrupt. This applies whether or not FX2LP is connected to the USB. The FX2LP exits the power-down (USB suspend) state using one of the following methods: • USB bus activity (if D+/D– lines are left floating, noise on these lines may indicate activity to the FX2LP and initiate a wakeup). • External logic asserts the WAKEUP pin • External logic asserts the PA3/WU2 pin. The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This allows a simple external R-C network to be used as a periodic wakeup source. Note that WAKEUP is by default active LOW. 3.10 Program/Data RAM 3.10.1 Size The FX2LP has 16 KBytes of internal program/data RAM, where PSEN#/RD# signals are internally ORed to allow the 8051 to access it as both program and data memory. No USB control registers appear in this space. Two memory maps are shown in the following diagrams: Figure 3-3 Internal Code Memory, EA = 0 Figure 3-4 External Code Memory, EA = 1. 3.10.2 Internal Code Memory, EA = 0 This mode implements the internal 16-KByte block of RAM (starting at 0) as combined code and data memory. When external RAM or ROM is added, the external read and write strobes are suppressed for memory spaces that exist inside the chip. This allows the user to connect a 64-KByte memory without requiring address decodes to keep clear of internal memory spaces. Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM spaces have the following access: • USB download • USB upload • Set-up data pointer • I2C interface boot load. 3.10.3 External Code Memory, EA = 1 The bottom 16 KBytes of program memory is external, and therefore the bottom 16 KBytes of internal RAM is accessible only as data memory.

Document #: 38-08032 Rev. *K Page 10 of 60 [+] Feedback CY7C68013A/CY7C68014A CY7C68015A/CY7C68016A 3.13 External FIFO Interface 3.13.1 Architecture The FX2LP slave FIFO architecture has eight 512-byte blocks in the endpoint RAM that directly serve as FIFO memories, and are controlled by FIFO control signals (such as IFCLK, SLCS#, SLRD, SLWR, SLOE, PKTEND, and flags). In operation, some of the eight RAM blocks fill or empty from the SIE, while the others are connected to the I/O transfer logic. The transfer logic takes two forms, the GPIF for internally generated control signals, or the slave FIFO interface for externally controlled transfers. 3.13.2 Master/Slave Control Signals The FX2LP endpoint FIFOS are implemented as eight physically distinct 256x16 RAM blocks. The 8051/SIE can switch any of the RAM blocks between two domains, the USB (SIE) domain and the 8051-I/O Unit domain. This switching is done virtually instantaneously, giving essentially zero transfer time between “USB FIFOS” and “Slave FIFOS.” Since they are physically the same memory, no bytes are actually transferred between buffers. At any given time, some RAM blocks are filling/emptying with USB data under SIE control, while other RAM blocks are available to the 8051 and/or the I/O control unit. The RAM blocks operate as single-port in the USB domain, and dual-port in the 8051-I/O domain. The blocks can be configured as single, double, triple, or quad buffered as previously shown. The I/O control unit implements either an internal-master (M for master) or external-master (S for Slave) interface. In Master (M) mode, the GPIF internally controls FIFOADR[1..0] to select a FIFO. The RDY pins (two in the 56-pin package, six in the 100-pin and 128-pin packages) can be used as flag inputs from an external FIFO or other logic if desired. The GPIF can be run from either an internally derived clock or externally supplied clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s (48-MHz IFCLK with 16-bit interface). In Slave (S) mode, the FX2LP accepts either an internally derived clock or externally supplied clock (IFCLK, max. frequency 48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals from external logic. When using an external IFCLK, the external clock must be present before switching to the external clock with the IFCLKSRC bit. Each endpoint can individually be selected for byte or word operation by an internal configuration bit, and a Slave FIFO Output Enable signal SLOE enables data of the selected width. External logic must insure that the output enable signal is inactive when writing data to a slave FIFO. The slave interface can also operate asynchronously, where the SLRD and SLWR signals act directly as strobes, rather than a clock qualifier as in synchronous mode. The signals SLRD, SLWR, SLOE and PKTEND are gated by the signal SLCS#. Document #: 38-08032 Rev. *K 3.13.3 GPIF and FIFO Clock Rates An 8051 register bit selects one of two frequencies for the internally supplied interface clock: 30 MHz and 48 MHz. Alternatively, an externally supplied clock of 5 MHz–48 MHz feeding the IFCLK pin can be used as the interface clock. IFCLK can be configured to function as an output clock when the GPIF and FIFOs are internally clocked. An output enable bit in the IFCONFIG register turns this clock output off, if desired. Another bit within the IFCONFIG register will invert the IFCLK signal whether internally or externally sourced. 3.14 GPIF The GPIF is a flexible 8- or 16-bit parallel interface driven by a user-programmable finite state machine. It allows the CY7C68013A/15A to perform local bus mastering, and can implement a wide variety of protocols such as ATA interface, printer parallel port, and Utopia. The GPIF has six programmable control outputs (CTL), nine address outputs (GPIFADRx), and six general-purpose ready inputs (RDY). The data bus width can be 8 or 16 bits. Each GPIF vector defines the state of the control outputs, and determines what state a ready input (or multiple inputs) must be before proceeding. The GPIF vector can be programmed to advance a FIFO to the next data value, advance an address, etc. A sequence of the GPIF vectors make up a single waveform that will be executed to perform the desired data move between the FX2LP and the external device. 3.14.1 Six Control OUT Signals The 100- and 128-pin packages bring out all six Control Output pins (CTL0-CTL5). The 8051 programs the GPIF unit to define the CTL waveforms. The 56-pin package brings out three of these signals, CTL0–CTL2. CTLx waveform edges can be programmed to make transitions as fast as once per clock (20.8 ns using a 48-MHz clock). 3.14.2 Six Ready IN Signals The 100- and 128-pin packages bring out all six Ready inputs (RDY0–RDY5). The 8051 programs the GPIF unit to test the RDY pins for GPIF branching. The 56-pin package brings out two of these signals, RDY0–1. 3.14.3 Nine GPIF Address OUT Signals Nine GPIF address lines are available in the 100- and 128-pin packages, GPIFADR[8..0]. The GPIF address lines allow indexing through up to a 512-byte block of RAM. If more address lines are needed, I/O port pins can be used. 3.14.4 Long Transfer Mode In master mode, the 8051 appropriately sets GPIF transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or GPIFTCB0) for unattended transfers of up to 232 transactions. The GPIF automatically throttles data flow to prevent under or overflow until the full number of requested transactions complete. The GPIF decrements the value in these registers to represent the current status of the transaction.

There are two ECC configurations: Two ECCs, each calculated over 256 bytes (SmartMedia Standard); and one ECC calculated over 512 bytes. FX2LP has one I2C port that is driven by two internal controllers, one that automatically operates at boot time to load VID/PID/DID and configuration information, and another that the 8051, once running, uses to control external I2C devices. The I2C port operates in master mode only. The ECC can correct any one-bit error or detect any two-bit error. 3.18.1 I2C Port Pins 2 3.15.1 ECC Implementation The two ECC configurations are selected by the ECCM bit: 3.15.1.1 ECCM = 0 Two 3-byte ECCs, each calculated over a 256-byte block of data. This configuration conforms to the SmartMedia Standard. Write any value to ECCRESET, then pass data across the GPIF or Slave FIFO interface. The ECC for the first 256 bytes of data will be calculated and stored in ECC1. The ECC for the next 256 bytes will be stored in ECC2. After the second ECC is calculated, the values in the ECCx registers will not change until ECCRESET is written again, even if more data is subsequently passed across the interface. 3.15.1.2 ECCM = 1 The I C pins SCL and SDA must have external 2.2-kΩ pull-up resistors even if no EEPROM is connected to the FX2LP. External EEPROM device address pins must be configured properly. See Table 3-8 for configuring the device address pins. Table 3-8.

Write any value to ECCRESET then pass data across the GPIF or Slave FIFO interface. The ECC for the first 512 bytes of data will be calculated and stored in ECC1; ECC2 is unused. After the ECC is calculated, the value in ECC1 will not change until ECCRESET is written again, even if more data is subsequently passed across the interface 3.16 USB Uploads and Downloads The core has the ability to directly edit the data contents of the internal 16-KByte RAM and of the internal 512-byte scratch pad RAM via a vendor-specific command. This capability is normally used when “soft” downloading user code and is available only to and from internal RAM, only when the 8051 is held in reset. The available RAM spaces are 16 KBytes from 0x0000–0x3FFF (code/data) and 512 bytes from 0xE000–0xE1FF (scratch pad data RAM).[8] 3.17 Autopointer Access FX2LP provides two identical autopointers. They are similar to the internal 8051 data pointers, but with an additional feature: they can optionally increment after every memory access. This capability is available to and from both internal and external RAM. The autopointers are available in external FX2LP registers, under control of a mode bit (AUTOPTRSET-UP.0). Using the external FX2LP autopointer access (at 0xE67B – 0xE67C) allows the autopointer to access all RAM, internal and external to the part. Also, the autopointers can point to any FX2LP register or endpoint buffer space. When autopointer access to external memory is enabled, location 0xE67B and 0xE67C in XDATA and code space cannot be used. Example EEPROM 16 3.18.2 I2C Interface Boot Load Access At power-on reset the I2C interface boot loader will load the VID/PID/DID configuration bytes and up to 16 KBytes of program/data. The available RAM spaces are 16 KBytes from 0x0000–0x3FFF and 512 bytes from 0xE000–0xE1FF. The 8051 will be in reset. I2C interface boot loads only occur after power-on reset. 3.18.3 I2C Interface General-Purpose Access The 8051 can control peripherals connected to the I2C bus using the I2CTL and I2DAT registers. FX2LP provides I2C master control only, it is never an I2C slave. 3.19 Compatible with Previous Generation EZ-USB FX2 The EZ-USB FX2LP is form/fit and with minor exceptions functionally compatible with its predecessor, the EZ-USB FX2. This makes for an easy transition for designers wanting to upgrade their systems from the FX2 to the FX2LP. The pinout and package selection are identical, and the vast majority of firmware previously developed for the FX2 will function in the FX2LP. For designers migrating from the FX2 to the FX2LP a change in the bill of material and review of the memory allocation (due to increased internal memory) is required for more information about migrating from EZ-USB FX2 to EZ-USB FX2LP, please see further details in the application note titled Migrating from EZ-USB FX2 to EZ-USB FX2LP, which is available on the Cypress Website. Notes: 7. To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation. 8. After the data has been downloaded from the host, a “loader” can execute from internal RAM in order to transfer downloaded data to external memory. 9. This EEPROM does not have address pins.

CY7C68015A is identical to CY7C68016A in form, fit, and functionality. CY7C68014A and CY7C68016A have a lower suspend current than CY7C68013A and CY7C68015A respectively. CY7C68014A and CY7C68016A have a lower suspend current than CY7C68013A and CY7C68015A respectively: hence are ideal for power-sensitive battery applications. CY7C68015A and CY7C68016A are available in 56-pin QFN package only. Two additional GPIO signals are available on the CY7C68015A and CY7C68016A to provide more flexibility when neither IFCLK or CLKOUT are needed in the 56-pin Document #: 38-08032 Rev. *K package. The USB developers who want to convert their FX2 56-pin application to a bus-powered system will directly benefit from these additional signals. The two GPIOs will give these developers the signals they need for the power control circuitry of their bus-powered application without pushing them to a high-pincount version of FX2LP. The CY7C68015A is only available in the 56-pin QFN package Table 3-10.

The following pages illustrate the individual pin diagrams, plus a combination diagram showing which of the full set of signals are available in the 128-, 100-, and 56-pin packages. The signals on the left edge of the 56-pin package in Figure 4-1 are common to all versions in the FX2LP family with the noted differences between the CY7C68013A and the CY7C68015A. Three modes are available in all package versions: Port, GPIF master, and Slave FIFO. These modes define the signals on the right edge of the diagram. The 8051 selects the interface mode using the IFCONFIG[1:0] register bits. Port mode is the power-on default configuration. The 100-pin package adds functionality to the 56-pin package by adding these pins: • PORTC or alternate GPIFADR[7:0] address signals Document #: 38-08032 Rev. *K • PORTE or alternate GPIFADR[8] address signal and seven additional 8051 signals • Three GPIF Control signals • Four GPIF Ready signals • Nine 8051 signals (two USARTs, three timer inputs, INT4,and INT5#) • BKPT, RD#, WR#. The 128-pin package adds the 8051 address and data buses plus control signals. Note that two of the required signals, RD# and WR#, are present in the 100-pin version. In the 100-pin and 128-pin versions, an 8051 control bit can be set to pulse the RD# and WR# pins when the 8051 reads from/writes to PORTC. This feature is enabled by setting PORTCSTB bit in CPUCS register. Section 10.5 displays the timing diagram of the read and write strobing function on accessing PORTC.

This bidirectional bus is high-impedance when inactive, input for bus reads, and output for bus writes. The data bus is used for external 8051 program and data memory. The data bus is active only for external bus accesses, and is driven LOW in suspend. Program Store Enable. This active-LOW signal indicates an 8051 code fetch from external memory. It is active for program memory fetches from 0x4000–0xFFFF when the EA pin is LOW, or from 0x0000–0xFFFF when the EA pin is HIGH. Note: 10. Unused inputs should not be left floating. Tie either HIGH or LOW as appropriate. Outputs should only be pulled up or down to ensure signals at power-up and in standby. Note also that no pins should be driven while the device is powered down.

This pin goes active (HIGH) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are enabled in the BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT register is HIGH, this signal pulses HIGH for eight 12-/24-/48-MHz clocks. If the BPPULSE bit is LOW, the signal remains HIGH until the 8051 clears the BREAK bit (by writing 1 to it) in the BREAKPT register. RESET# Input N/A Active LOW Reset. Resets the entire chip. See section 3.9 ”Reset and Wakeup” on page 6 for more details. EA Input N/A External Access. This pin determines where the 8051 fetches code between addresses 0x0000 and 0x3FFF. If EA = 0 the 8051 fetches this code from its internal RAM. IF EA = 1 the 8051 fetches this code from external memory. Input N/A Crystal Input. Connect this signal to a 24-MHz parallel-resonant, fundamental mode crystal and load capacitor to GND. It is also correct to drive XTALIN with an external 24-MHz square wave derived from another clock source. When driving from an external source, the driving signal should be a 3.3V square wave.

IFCLK may be inverted, whether internally or externally sourced, by setting the bit IFCONFIG.4 =1. ------------------ ----------- ---------- ----------------------------------------------------------------------Multiplexed pin whose function is selected by the PE0 or I/O/Z I T0OUT on (PE0) PORTECFG.0 bit. PE0 is a bidirectional I/O port pin. CY7C68015A 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.

In these 100-pin and 128-pin versions, an 8051 control bit can be set to pulse the RD# and WR# pins when the 8051 reads from/writes to PORTC. This feature is enabled by setting PORTCSTB bit in CPUCS register. The RD# and WR# strobes are asserted for two CLKOUT cycles when PORTC is accessed. The WR# strobe will be asserted two clock cycles after PORTC is updated and will be active for two clock cycles after that as shown in Figure 10-4. As for read, the value of PORTC three clock cycles before the assertion of RD# is the value that the 8051 reads in. The RD# is pulsed for 2 clock cycles after 3 clock cycles from the point when the 8051 has performed a read function on PORTC. The way the feature is intended to work is that the RD# signal will prompt the external logic to prepare the next data byte. Nothing gets sampled internally on assertion of the RD# signal itself. It is just a “prefetch” type signal to get the next data byte prepared. So, using it with that in mind should easily meet the set-up time to the next read. The purpose of this pulsing of RD# is to let the external peripheral know that the 8051 is done reading PORTC and the data was latched into PORTC three CLKOUT cycles prior to asserting the RD# signal. Once the RD# is pulsed the external logic may update the data on PORTC. Following is the timing diagram of the read and write strobing function on accessing PORTC. Refer to Section 10.3 and Section 10.4 for details on propagation delay of RD# and WR# signals. tCLKOUT CLKOUT PORTC IS UPDATED tSTBL tSTBH WR# Figure 10-4.

Document #: 38-08032 Rev. *K 13.5 ns Although there are no specific timing requirements for the PKTEND assertion, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte/word packet. There is an additional timing requirement that need to be met when the FIFO is configured to operate in Page 46 of 60 [+] Feedback CY7C68013A/CY7C68014A CY7C68015A/CY7C68016A Figure 10-12 shows a scenario where two packets are being committed. The first packet gets committed automatically when the number of bytes in the FIFO reaches X (value set in AUTOINLEN register) and the second one byte/word short packet being committed manually using PKTEND. Note that there is at least one IFCLK cycle timing between the assertion of PKTEND and clocking of the last byte of the previous packet (causing the packet to be committed automatically). Failing to adhere to this timing, will result in the FX2 failing to send the one byte/word short packet. auto mode and it is desired to send two packets back to back: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte/word packet committed manually using the PKTEND pin. In this particular scenario, user must make sure to assert PKTEND at least one clock cycle after the rising edge that caused the last byte/word to be clocked into the previous auto committed packet.

Slave FIFO Synchronous Sequence of Events Diagram Figure 10-18 shows the timing relationship of the SLAVE FIFO signals during a synchronous FIFO read using IFCLK as the synchronizing clock. The diagram illustrates a single read followed by a burst read. • At t = 0 the FIFO address is stable and the signal SLCS is asserted (SLCS may be tied low in some applications). Note: tSFA has a minimum of 25 ns. This means when IFCLK is running at 48 MHz, the FIFO address set-up time is more than one IFCLK cycle. • At t = 1, SLOE is asserted. SLOE is an output enable only, whose sole function is to drive the data bus. The data that is driven on the bus is the data that the internal FIFO pointer is currently pointing to. In this example it is the first data value in the FIFO. Note: the data is pre-fetched and is driven on the bus when SLOE is asserted. • At t = 2, SLRD is asserted. SLRD must meet the set-up time of tSRD (time from asserting the SLRD signal to the rising edge of the IFCLK) and maintain a minimum hold time of tRDH (time from the IFCLK edge to the deassertion of the SLRD signal). If the SLCS signal is used, it must be asserted Document #: 38-08032 Rev. *K before SLRD is asserted (i.e., the SLCS and SLRD signals must both be asserted to start a valid read condition). • The FIFO pointer is updated on the rising edge of the IFCLK, while SLRD is asserted. This starts the propagation of data from the newly addressed location to the data bus. After a propagation delay of tXFD (measured from the rising edge of IFCLK) the new data value is present. N is the first data value read from the FIFO. In order to have data on the FIFO data bus, SLOE MUST also be asserted. The same sequence of events are shown for a burst read and are marked with the time indicators of T = 0 through 5. Note: For the burst mode, the SLRD and SLOE are left asserted during the entire duration of the read. In the burst read mode, when SLOE is asserted, data indexed by the FIFO pointer is on the data bus. During the first read cycle, on the rising edge of the clock the FIFO pointer is updated and increments to point to address N+1. For each subsequent rising edge of IFCLK, while the SLRD is asserted, the FIFO pointer is incremented and the next data value is placed on the data bus.

Slave FIFO Synchronous Write Sequence and Timing Diagram[20] The Figure 10-20 shows the timing relationship of the SLAVE FIFO signals during a synchronous write using IFCLK as the synchronizing clock. The diagram illustrates a single write followed by burst write of 3 bytes and committing all 4 bytes as a short packet using the PKTEND pin. • At t = 0 the FIFO address is stable and the signal SLCS is asserted. (SLCS may be tied low in some applications) Note: tSFA has a minimum of 25 ns. This means when IFCLK is running at 48 MHz, the FIFO address set-up time is more than one IFCLK cycle. • At t = 1, the external master/peripheral must outputs the data value onto the data bus with a minimum set up time of tSFD before the rising edge of IFCLK. • At t = 2, SLWR is asserted. The SLWR must meet the set-up time of tSWR (time from asserting the SLWR signal to the rising edge of IFCLK) and maintain a minimum hold time of tWRH (time from the IFCLK edge to the deassertion of the SLWR signal). If SLCS signal is used, it must be asserted with SLWR or before SLWR is asserted. (i.e., the SLCS and SLWR signals must both be asserted to start a valid write condition). • While the SLWR is asserted, data is written to the FIFO and on the rising edge of the IFCLK, the FIFO pointer is incremented. The FIFO flag will also be updated after a delay of tXFLG from the rising edge of the clock. The same sequence of events are also shown for a burst write and are marked with the time indicators of T = 0 through 5. Note: For the burst mode, SLWR and SLCS are left asserted for the entire duration of writing all the required data values. In this burst write mode, once the SLWR is asserted, the data on the FIFO data bus is written to the FIFO on every rising edge Document #: 38-08032 Rev. *K of IFCLK. The FIFO pointer is updated on each rising edge of IFCLK. In Figure 10-20, once the four bytes are written to the FIFO, SLWR is deasserted. The short 4-byte packet can be committed to the host by asserting the PKTEND signal. There is no specific timing requirement that needs to be met for asserting PKTEND signal with regards to asserting the SLWR signal. PKTEND can be asserted with the last data value or thereafter. The only requirement is that the set-up time tSPE and the hold time tPEH must be met. In the scenario of Figure 10-20, the number of data values committed includes the last value written to the FIFO. In this example, both the data value and the PKTEND signal are clocked on the same rising edge of IFCLK. PKTEND can also be asserted in subsequent clock cycles. The FIFOADDR lines should be held constant during the PKTEND assertion. Although there are no specific timing requirement for the PKTEND assertion, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte/word packet. Additional timing requirements exists when the FIFO is configured to operate in auto mode and it is desired to send two packets: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte/word packet committed manually using the PKTEND pin. In this case, the external master must make sure to assert the PKTEND pin at least one clock cycle after the rising edge that caused the last byte/word to be clocked into the previous auto committed packet (the packet with the number of bytes equal to what is set in the AUTOINLEN register). Refer to Figure 10-12 for further details on this timing.

Slave FIFO Asynchronous Read Sequence of Events Diagram Figure 10-21 diagrams the timing relationship of the SLAVE FIFO signals during an asynchronous FIFO read. It shows a single read followed by a burst read. • At t = 0 the FIFO address is stable and the SLCS signal is asserted. • At t = 1, SLOE is asserted. This results in the data bus being driven. The data that is driven on to the bus is previous data, it data that was in the FIFO from a prior read cycle. • At t = 2, SLRD is asserted. The SLRD must meet the minimum active pulse of tRDpwl and minimum de-active pulse width of tRDpwh. If SLCS is used then, SLCS must be asserted before SLRD is asserted (i.e., the SLCS and SLRD signals must both be asserted to start a valid read condition.) Document #: 38-08032 Rev. *K • The data that will be driven, after asserting SLRD, is the updated data from the FIFO. This data is valid after a propagation delay of tXFD from the activating edge of SLRD. In Figure 10-21, data N is the first valid data read from the FIFO. For data to appear on the data bus during the read cycle (i.e.,SLRD is asserted), SLOE MUST be in an asserted state. SLRD and SLOE can also be tied together. The same sequence of events is also shown for a burst read marked with T = 0 through 5. Note: In burst read mode, during SLOE is assertion, the data bus is in a driven state and outputs the previous data. Once SLRD is asserted, the data from the FIFO is driven on the data bus (SLOE must also be asserted) and then the FIFO pointer is incremented.

If SLCS is used, it must also be asserted (SLCS may be tied low in some applications). • At t = 1 SLWR is asserted. SLWR must meet the minimum active pulse of tWRpwl and minimum de-active pulse width of tWRpwh. If the SLCS is used, it must be in asserted with SLWR or before SLWR is asserted. • At t = 2, data must be present on the bus tSFD before the deasserting edge of SLWR. • At t = 3, deasserting SLWR will cause the data to be written from the data bus to the FIFO and then increments the FIFO Document #: 38-08032 Rev. *K pointer. The FIFO flag is also updated after tXFLG from the deasserting edge of SLWR. The same sequence of events are shown for a burst write and is indicated by the timing marks of T = 0 through 5. Note: In the burst write mode, once SLWR is deasserted, the data is written to the FIFO and then the FIFO pointer is incremented to the next byte in the FIFO. The FIFO pointer is post incremented. In Figure 10-23 once the four bytes are written to the FIFO and SLWR is deasserted, the short 4-byte packet can be committed to the host using the PKTEND. The external device should be designed to not assert SLWR and the PKTEND signal at the same time. It should be designed to assert the PKTEND after SLWR is deasserted and met the minimum deasserted pulse width. The FIFOADDR lines are to be held constant during the PKTEND assertion.

Do not allow the plane to be split under these traces. • It is preferred is to have no vias placed on the DPLUS or DMINUS trace routing. • Isolate the DPLUS and DMINUS traces from all other signal traces by no less than 10 mm. 14.0 Quad Flat Package No Leads (QFN) Package Design Notes Electrical contact of the part to the Printed Circuit Board (PCB) is made by soldering the leads on the bottom surface of the package to the PCB. Hence, special attention is required to the heat transfer area below the package to provide a good thermal bond to the circuit board. A Copper (Cu) fill is to be designed into the PCB as a thermal pad under the package. Heat is transferred from the FX2LP through the device’s metal paddle on the bottom side of the package. Heat from here, is conducted to the PCB at the thermal pad. It is then conducted Note: 24.
