Product details
Overview
CY7C68016A-56LTXCT from Infineon Technologies (formerly Cypress Semiconductor) is a high-speed USB 2.0 peripheral controller integrating a USB 2.0 transceiver, smart serial interface engine (SIE), enhanced 8051 microcontroller, and GPIF™ programmable interface in a single 56-pin QFN package. It delivers up to 53 MB/s data throughput, supports 48/24/12 MHz CPU operation, features 16 KB on-chip RAM, four configurable BULK/INTERRUPT/ISOCHRONOUS endpoints with double/triple/quad buffering, and draws only 100 µA typical 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-56LTXCT datasheet, CY7C68016A-56LTXCT pinout, CY7C68016A-56LTXCT application, or CY7C68016A-56LTXCT equivalent, key selection criteria include its USB 2.0 Hi-Speed certification (TID #40460272), 56-pin QFN footprint with 26 GPIOs, GPIF waveform programmability for glueless ASIC/DSP interfacing, and dual USART support for embedded host-side protocol bridging.
Technical Context
The CY7C68016A implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading enumeration, token handling, and error recovery from the 8051 core. Its 48-MHz-capable enhanced 8051 executes firmware from internal RAM (downloaded via USB or loaded from EEPROM), supporting real-time endpoint management without external code storage.
GPIF™ operates as an independent state-machine-based interface controller with six CTL outputs, six RDY inputs, and programmable waveform descriptors - enabling direct, synchronous/asynchronous connection to ATA, EPP, PCMCIA, or custom parallel buses at up to 96 MB/s burst rates. The device supports both master and slave FIFO modes with automatic 8-/16-bit bus width conversion.
