 CY7C68053 Features
• USB 2.0 – USB-IF High-Speed and Full-Speed Compliant 
(TID# 40000188)
• Single-chip integrated USB 2.0 transceiver, smart SIE, and 
enhanced 8051 microprocessor
• Ideal for mobile applications (cell phone, smart phones, 
PDAs, MP3 players)
— Ultra low power
— Suspend current: 20 µA (typical)
• Software: 8051 code runs from:
— Internal RAM, which is loaded from EEPROM
• 16 kBytes of on-chip Code/Data RAM
• Four programmable BULK/INTERRUPT/ISOCHRONOUS 
endpoints
— Buffering options: double, triple, and quad
• Additional programmable (BULK/INTERRUPT) 64-byte 
endpoint
• 8- or 16-bit external data interface
• Smart Media Standard ECC generation
• GPIF (General Programmable Interface)
— Allows direct connection to most parallel interface
— Programmable waveform descriptors and configuration 
registers to define waveforms
— Supports multiple Ready (RDY) inputs and Control (CTL) 
outputs
• Integrated, industry standard enhanced 8051
— 48 MHz, 24 MHz, or 12 MHz CPU operation
— Four clocks per instruction cycle
— Three counter/timers
— Expanded interrupt system
— Two data pointers
• 1.8V core operation
• 1.8V - 3.3V IO operation
• Vectored USB interrupts and GPIF/FIFO interrupts
• Separate data buffers for the Set-up and Data portions of a 
CONTROL transfer
• Integrated I
2
C™ controller, runs at 100 or 400 kHz
• Four integrated FIFO’s
— Integrated glue logic and FIFO’s lower system cost
— Automatic conversion to and from 16-bit buses
— Master or slave operation
— Uses external clock or asynchronous strobes
— Easy interface to ASIC and DSP IC’s
• Available in Industrial temperature grade
• Available in one lead-free package with up to 24 GPIO’s
— 56-pin VFBGA (24 GPIO’s)
