A complete functional description is available in the AT89C5131A-M datasheet. AT89C5131A-L is a high-performance Flash version of the 80C51 single-chip 8-bit microcontrollers with full speed USB functions. AT89C5131A-L features a full-speed USB module compatible with the USB specifications Version and This module integrates the USB transceivers with a 3.3V voltage regulator 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 up to 6 versatile Endpoints EP1/EP2/EP3/EP4/EP5/EP6 with minimum software overhead are also part of the USB module. AT89C5131A-L retains the features of the Atmel 80C52 with extended Flash capacity 32-Kbyte , 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. In addition, AT89C5131A-L has an on-chip expanded RAM of 1024 bytes ERAM , a dual- data pointer, a 16-bit up/down Timer T2 , a Programmable Counter Array PCA , up to 4 programmable LED current sources, a programmable hardware watchdog and a power-on reset. AT89C5131A-L has two software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial ports and the interrupt system are still operating. In the power-down mode the RAM is saved, the peripheral clock is frozen, but the device has full wake-up capability through USB events or external interrupts. 2 AT89C5131A-L Block Diagram AT89C5131A-L RxD TxD VDD ECI CEX T2EX T2 SCL SDA MISO MOSI SCK XTAL1 XTAL2 ALE PSEN EA RD 2 WR 2 EEPROM ERAM EUART + RAM 256x8 32Kx8 Flash 4Kx8 1Kx8 PCA Timer2 TWI C51 CORE Timer 0 INT Timer 1 Ctrl Parallel I/O Ports & Ext.
