Infineon Technologies CY7C68053-56BAXIT

Overview

CY7C68053-56BAXIT from Cypress Semiconductor is a 1.8 V core, USB 2.0 high-speed (480 Mbps) microcontroller integrating an enhanced 8051 CPU, USB transceiver, smart serial interface engine (SIE), four programmable endpoints, and General Programmable Interface (GPIF). It delivers up to 53 MB/s burst throughput in mobile and embedded host-peripheral bridge applications such as smartphone baseband interfacing and secure USB HDD dongles.

For engineers reviewing the CY7C68053-56BAXIT datasheet, CY7C68053-56BAXIT pinout, CY7C68053-56BAXIT application, or CY7C68053-56BAXIT equivalent, key selection criteria include suspend current (20 µA typ), 16 kB on-chip RAM, 8/16-bit external FIFO interface, I²C master support (100/400 kHz), and GPIF waveform programmability for glueless ASIC/DSP interfacing.

Technical Context

The CY7C68053 implements a dual-clock architecture: a 24 MHz crystal feeds a 20× PLL to generate 480 MHz for the USB PHY, while internal dividers produce selectable 12/24/48 MHz clocks for the 8051 core (four clocks per instruction cycle). Its Smart SIE offloads full USB 2.0 protocol handling-including SETUP/data phase separation, endpoint buffering, and descriptor management-freeing the CPU for application logic.

GPIF operates as a fully autonomous state machine with programmable waveform descriptors, supporting master/slave 8- or 16-bit parallel interfaces (e.g., ATA, UTOPIA, PCMCIA) via dedicated RDY/CTL signals and automatic bus-width conversion. ECC generation is integrated for SmartMedia-compatible NAND flash interfacing.

FAQ

What boot methods does CY7C68053-56BAXIT support?

The CY7C68053-56BAXIT supports I²C EEPROM bootloading (with 0xC2 header detection) and external processor emulation of I²C slave. It does not store default USB descriptors internally - all device identity and enumeration behavior is defined by loaded firmware, enabling field-upgradable configurations via ReNumeration™.

Does CY7C68053-56BAXIT 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 20× PLL uses this reference to generate the 480 MHz USB PHY clock and derive 12/24/48 MHz CPU clocks. No internal RC oscillator is provided for USB timing-critical operation.

Can CY7C68053-56BAXIT operate as a USB host?

No - it functions exclusively as a USB 2.0 peripheral (device mode). It contains no USB host controller logic, OTG support, or VBUS sensing circuitry. Its architecture is optimized for endpoint-based data transfer under host direction, not host-initiated enumeration or transaction scheduling.

How many GPIOs are available in the 56-pin VFBGA package?

The CY7C68053-56BAXIT provides up to 24 GPIOs in its 56-pin VFBGA package. These are distributed across Ports A, B, C, and D, with Port B and Port D multiplexed for the 8/16-bit FIFO interface. GPIO functionality is configurable via firmware-controlled SFRs including OEA–OED and IOA–IOD registers.
