AT83C5134 概述
AT83C5134/35/36 are high performance ROM versions of the 80C51 single-chip 8-bit microcontrollers with full speed USB functions.
AT83C5134/35/36 features a full-speed USB module compatible with the USB specifications Version 2.0. This module integrates the USB transceivers and the Serial Interface Engine (SIE) with Digital Phase Locked Loop and 48 MHz clock recovery. USB Event detection logic (Reset and Suspend/Resume) and FIFO buffers supporting the mandatory control Endpoint (EP0) and 5 versatile Endpoints (EP1/EP2/EP3/EP4/EP5) with minimum software overhead are also part of the USB module.
AT83C5134/35/36 retains the features of the Atmel 80C52 with extended ROM cpacity (8/16/32Kbytes), 256 bytes of internal RAM, a 4-level interrupt system, two 16-bit timer/counters (T0/T1),a full duplex enhanced UART (EUART) and an on-chip oscillator.
