Infineon Technologies CY7C68013A-100AXC

Overview

CY7C68013A-100AXC from Infineon Technologies (formerly Cypress Semiconductor) is a USB 2.0 high-speed peripheral controller integrating an enhanced 8051 microprocessor, USB 2.0 transceiver, serial interface engine (SIE), and general programmable interface (GPIF) in a single 100-pin TQFP package. It delivers up to 53 MB/s data throughput, supports four programmable endpoints with double/triple/quad buffering, and operates at 12/24/48 MHz CPU clock with 16 KB on-chip RAM - enabling bus-powered video capture and firmware-upgradable USB peripherals.

For engineers reviewing the CY7C68013A-100AXC datasheet, CY7C68013A-100AXC pinout, CY7C68013A-100AXC application, or CY7C68013A-100AXC equivalent, key selection criteria include its GPIF waveform programmability, 8-/16-bit external FIFO interface, suspend current of 300 µA (typ), I²C controller (100/400 kHz), and compatibility with legacy FX2 firmware and hardware layouts.

Technical Context

The CY7C68013A implements a hardware-accelerated USB 2.0 stack via its Smart SIE, offloading protocol handling (including SETUP/data stage separation, PID generation, CRC checking) from the 8051 core. Its PLL derives 480 MHz for the PHY from a 24 MHz crystal while generating 12/24/48 MHz clocks for the CPU via internal dividers.

GPIF operates as a state-machine-driven parallel interface with six CTL outputs, six RDY inputs, and configurable waveform descriptors - enabling direct glueless connection to ATA, EPP, PCMCIA, SRAM, and FPGA interfaces without external logic. The integrated I²C controller supports master mode only at nominal 100/400 kHz (measured ~85/300 kHz).

FAQ

Is CY7C68013A-100AXC pin-compatible with the original CY7C68013?

Yes, CY7C68013A-100AXC is pin-compatible, object-code-compatible, and functionally compatible with the CY7C68013 FX2 in the 100-pin TQFP package. It retains identical pin assignments, memory map, and register layout while adding enhanced features like increased RAM and lower power consumption.

What boot methods does CY7C68013A-100AXC support?

CY7C68013A-100AXC supports three boot methods: (1) firmware download via USB during enumeration, (2) loading from internal EEPROM (I²C-connected), and (3) execution from external memory via the 8-/16-bit data bus - enabling flexible firmware updates and field reconfiguration without dedicated programmers.

Can CY7C68013A-100AXC operate as a USB host?

No, CY7C68013A-100AXC is a USB peripheral-only controller. It implements only device-side functionality (including SIE, transceiver, and endpoint buffers) and lacks OTG support, host controller logic, or VBUS sensing circuitry required for host operation.

Does CY7C68013A-100AXC 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 uses this crystal to generate the 480 MHz PHY clock and derive 12/24/48 MHz CPU clocks - no internal RC oscillator is provided for USB timing compliance.
