Infineon Technologies CY7C68013A-56LTXI

Overview

CY7C68013A-56LTXI 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 General Programmable Interface (GPIF) in a single 56-pin QFN package. It delivers up to 53 MB/s data throughput, supports 48/24/12 MHz CPU operation, includes 16 KB on-chip RAM, and targets bus-powered USB peripheral designs such as video capture dongles and memory card readers.

For engineers reviewing the CY7C68013A-56LTXI datasheet, CY7C68013A-56LTXI pinout, CY7C68013A-56LTXI application, or CY7C68013A-56LTXI equivalent, key selection criteria include suspend current (300 µA typ), GPIF waveform programmability, endpoint buffering options (double/triple/quad), and compatibility with legacy FX2 firmware and hardware layouts.

Technical Context

The CY7C68013A implements a hardware-accelerated USB 2.0 protocol stack via its Smart SIE, offloading enumeration, token handling, and CRC generation from the 8051 core. Its PLL-derived 480 MHz PHY clock enables Hi-Speed (480 Mbps) signaling while the 8051 runs at configurable 12/24/48 MHz using four clocks per instruction cycle.

GPIF operates independently of the CPU, supporting programmable 8-/16-bit parallel waveforms with up to six RDY inputs and six CTL outputs. Four integrated FIFOs-each configurable as master or slave-enable glueless interfacing to ATA, EPP, PCMCIA, or FPGA logic without external address latches or control logic.

FAQ

Is CY7C68013A-56LTXI pin-compatible with CY7C68013A-128AXC?

Yes, the CY7C68013A-56LTXI shares identical signal naming and functional pin mapping with the 128-pin TQFP variant for all common signals (USB D+/D−, CLKOUT, GPIF CTL/RDY, FIFO control lines). However, the 56-pin QFN exposes only 24 GPIOs versus 40 in the 128-pin package, limiting peripheral expansion capability.

What boot methods does CY7C68013A-56LTXI support?

The device supports three boot modes: (1) USB download of firmware into internal RAM at enumeration, (2) loading from external I²C EEPROM (address 0x50), and (3) execution from external memory via 8-bit data bus (requires 128-pin package). The 56-pin variant uses modes 1 or 2 exclusively.

Does CY7C68013A-56LTXI require an external crystal?

Yes, it requires a 24 MHz ±100 ppm parallel-resonant fundamental-mode crystal with 12 pF load capacitance. The on-chip PLL multiplies this to 480 MHz for the USB PHY; the 8051 clock is derived via integer division and can be set to 12/24/48 MHz via CPUCS register.

Can GPIF operate simultaneously with the 8051 CPU?

Yes, GPIF is a fully autonomous hardware block with dedicated state machine and waveform descriptor memory. It operates concurrently with the 8051 core, allowing continuous data transfer (e.g., video frame capture) while firmware processes USB requests or runs application logic.
