Product details
Overview
CY7C68016A-56LTXC from Infineon Technologies (formerly Cypress Semiconductor) is a USB 2.0 high-speed peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, smart serial interface engine (SIE), and general programmable interface (GPIF) in a single 56-pin QFN package. It delivers up to 53 MB/s data throughput, supports 48-MHz CPU operation, features 16 KB on-chip RAM, and draws only 100 µA typical current in suspend mode - enabling compact, bus- or battery-powered USB peripherals such as portable video recorders and memory card readers.
For engineers reviewing the CY7C68016A-56LTXC datasheet, CY7C68016A-56LTXC pinout, CY7C68016A-56LTXC application, or CY7C68016A-56LTXC equivalent, key selection criteria include its USB 2.0 Hi-Speed certification (TID #40460272), GPIF waveform programmability, dual USART support, 26 GPIOs in 56-pin QFN, and compatibility with FX2LP firmware and hardware design practices.
Technical Context
The CY7C68016A implements a dedicated USB 2.0 PHY with hardware-accelerated SIE handling protocol layers up to transaction level, offloading the 8051 core. Its PLL generates 480 MHz for the transceiver while deriving 48/24/12 MHz clocks for the CPU via internal dividers.
GPIF operates independently of the 8051, supporting programmable waveforms with up to six RDY inputs and six CTL outputs, enabling glueless interfacing to ATA, EPP, PCMCIA, and FPGA-based peripherals. The device includes four configurable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering and one additional 64-byte BULK/INTERRUPT endpoint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Hi-Speed (480 Mbps) and Full-Speed (12 Mbps); certified per USB-IF TID #40460272 - ensures interoperability with host controllers without custom driver development. |
| CPU Core | Enhanced 8051 running at 12/24/48 MHz (4 clocks/instruction); enables real-time USB protocol handling while executing application firmware in on-chip RAM. |
| On-chip RAM | 16 KB code/data RAM - sufficient to host full USB stack plus application logic without external memory, reducing BOM cost and PCB area. |
| Suspend Current | 100 µA typical - meets USB battery-powered device requirements and extends runtime in portable applications like scanners and MP3 players. |
| GPIO Count | 26 GPIOs in 56-pin QFN package - two more than CY7C68013A/14A, enabling expanded control signals or status indicators within identical footprint. |
| GPIF Interface | Programmable 8-/16-bit parallel interface with RDY/CTL signaling - eliminates need for external glue logic when connecting to ASICs, DSPs, or legacy buses like ATA. |
| I²C Controller | Integrated master-only I²C interface (configurable for ~85 kHz or ~300 kHz) - supports communication with EEPROM, sensors, or power management ICs without CPU overhead. |
Pinout & Package
Package: 56-pin QFN (7 mm × 7 mm, 0.5 mm pitch), RoHS-compliant, exposed thermal pad, industrial temperature grade (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D+ / D− | USB 2.0 differential data pair | Direct connection to USB connector; integrated transceiver eliminates external PHY and termination resistors. |
| CLKOUT | Configurable 8051 clock output | Provides 12/24/48 MHz clock signal with programmable inversion and tri-state - useful for synchronizing external logic or debugging timing. |
| INT | Interrupt request output | Asserted for USB setup packets, GPIF completion, or FIFO threshold events - enables low-latency event-driven firmware response. |
| SLCS# | Slave FIFO chip select | Enables slave FIFO mode for direct data transfer between external devices and USB endpoints without CPU intervention. |
| RDY0–RDY5 | GPIF ready inputs | Up to six asynchronous handshaking inputs allow precise timing control over external peripherals during GPIF waveform execution. |
| CTL0–CTL5 | GPIF control outputs | Six programmable outputs drive control lines (e.g., WR#, RD#, CS#) for external memory or interface chips under GPIF state machine control. |
Key Features
| Feature | Design Value |
|---|---|
| Smart Serial Interface Engine (SIE) | Hardware handles USB token, handshake, and data packet sequencing - reduces 8051 firmware complexity and guarantees USB compliance without protocol stack licensing. |
| General Programmable Interface (GPIF) | State-machine-driven parallel interface with user-defined waveforms - enables direct, high-bandwidth connection to FPGAs, DSPs, or legacy interfaces without external logic or DMA controllers. |
| Dual USARTs | Two independent UARTs with standard 8051 register mapping - support simultaneous debug console and peripheral communication (e.g., Bluetooth module or sensor bridge). |
| Flexible Boot Sources | Firmware loads from USB, internal RAM, or external EEPROM - simplifies field updates and eliminates need for dedicated programming hardware during production. |
| Four Configurable Endpoints | Supports BULK, INTERRUPT, and ISOCHRONOUS transfers with selectable buffering (double/triple/quad) - accommodates real-time streaming (video/audio) and reliable bulk data (storage) in same design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB peripheral controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C68013A-56LTXC | Same 56-pin QFN package, but 24 GPIOs and 300 µA suspend current - higher power consumption limits battery use. | Targeted at non-battery-powered systems where lower cost or legacy firmware reuse is prioritized. | Select when existing FX2LP firmware targets CY7C68013A and board layout cannot accommodate extra GPIOs. |
| CY7C68014A-56LTXC | Identical pinout and suspend current (100 µA), but lacks second USART and uses internal ROM boot instead of RAM-based flexibility. | Suitable for fixed-function devices requiring minimal firmware customization and no serial debug interface. | Choose when application requires ultra-low-power operation and does not need dual UARTs or dynamic firmware loading. |
Compared with CY7C68013A-56LTXC and CY7C68014A-56LTXC, the CY7C68016A-56LTXC uniquely combines 26 GPIOs, dual USARTs, and RAM-based boot - making it optimal for next-generation portable USB peripherals needing expandability, debug capability, and firmware agility.

FAQ
Is CY7C68016A-56LTXC pin-compatible with CY7C68013A-56LTXC?
Yes, CY7C68016A-56LTXC is pin-compatible with CY7C68013A-56LTXC in the 56-pin QFN package, sharing identical power, USB, reset, and clock pin assignments. However, two GPIO pins (PORTD.6 and PORTD.7) are repurposed as additional general-purpose I/Os in CY7C68016A, providing functional expansion without layout changes.
What boot methods does CY7C68016A-56LTXC support?
CY7C68016A-56LTXC supports three boot modes: (1) USB download of firmware into internal RAM, (2) loading from external I²C EEPROM, and (3) execution from external memory via 8-/16-bit data bus. Unlike CY7C68014A, it does not rely on internal ROM, enabling full firmware flexibility and field-upgradable behavior.
Does CY7C68016A-56LTXC require an external crystal?
Yes, CY7C68016A-56LTXC requires a 24 MHz ±100 ppm parallel-resonant fundamental-mode crystal connected to XIN/XOUT pins. The on-chip PLL multiplies this to 480 MHz for the USB transceiver, while internal dividers derive 48/24/12 MHz clocks for the 8051 core - no external oscillator or clock generator is needed.
Can CY7C68016A-56LTXC operate in low-power USB suspend mode?
Yes, CY7C68016A-56LTXC achieves 100 µA typical current draw in USB suspend mode, meeting USB specification requirements for bus-powered devices. This is enabled by internal clock gating and power-isolation circuitry, and is verified across the industrial temperature range (–40°C to +85°C).
