描述 Description

EM85F690A is a high-performance Flash version of the 80C52 single-chip 8-bit microcontroller with full speed USB functions.EM85F690A features a full-speed USB module compatible with the USB specifications Version 2.0. This module integrates the USB transceivers with a 3.3V voltage regulator and the Serial Interface Engine (SIE). USB Event detection logic (Reset and Suspend/Resume) and FIFO buffers supporting the mandatory control Endpoint (EP0) and up to four versatile Endpoints (EP1/EP2/EP3/EP4) with minimum software overhead are also part of the USB module. EM85F690A retains the features of the 80C52 with 256 bytes RAM, 2048 bytes XRAM, two 16-bit Timers/Counters (T0/T1), a full duplex UART and an on-chip oscillator. EM85F690A also has a built-in SPI, two I2C, six PWM peripheral functions
