AT76C713 Datasheet, PDF (1/4 Pages) ATMEL Corporation – High-speed (48 MHz) AVR Microcontroller with USB Interface

Features
• Advanced RISC Architecture, 130 Powerful Instructions, Most Single Clock Cycle
Execution
• Clock Generator Provides CPU Rates up to 48 MHz
• Only One External Clock Crystal of 12 MHz Can Generate All the Required System
Clocks:
– Internal Clock for Standard UART Rates
– A 48 MHz and 96 MHz Clock for USB Data Recovery
– AVR Processor and System Clock
• Full-speed USB Interface (12 Mbit/s) 2.0 Compliant
• Two On-chip 16550 UARTs Supporting Baud Rates up to 921 Kbaud
– Both UARTs Incorporate Individual Transmit and Receive FIFOs of 16 Bytes
– UART0 Supports Modem Control Signals
• Programmable SPI Interface
• On-chip Bootstrap ROM Provides a Variety of Firmware Upgrade Modes
– Device Firmware Upgrade Through USB for the Internal Program SRAM
(No External Non-volatile SPI Memory Required)
– Device Firmware Upgrade Through USB for both the Internal Program SRAM and
the External SPI DataFlash^® or EEPROM
– SPI Program Mode from the External DataFlash or EEPROM
• External Memory Interface Supporting up to 32 Kbytes of External RAM in Address
Multiplexed Mode, 2 Banks of 256 Bytes in Non-multiplexed Mode, FIFO, or with an
Extra 20 GPIOs
• DMA Channels Allow Fast Data Transfers between Endpoint Buffers and Internal or
External SRAM (The DMA Transfer Rate is 12 MHz for All Channels)
• 8K x 16 bits (up to 11K x 16 bits), In-System SRAM for Program Code (Program
Memory)
• On-chip 8 Kbytes SRAM for Data and Variables (Two, Four, and Eight Kbytes can be Re-
Mapped for Program Storage in the Address Area Above the Program Memory)
• Two 8-bit Timer/Counters
• One 16-bit Timer/Counter
• Four External Interrupts Through GPIOs
• Programmable Watchdog Timer
• Low Voltage Operation:
– 1.8V for the Core
– 1.8V or 3.3V for the Periphery
– 3.3V for the USB
• 100-pin TQFP Package
