AT89C5131
4136C–USB–04/05
Description
AT89C5131 is a high-performance Flash version of the 80C51 single-chip 8-bit micro-
controllers with full speed USB functions.
AT89C5131 features a full-speed USB module compatible with the USB specifications
Version 1.1 and 2.0. 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.
AT89C5131 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, AT89C5131 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.
AT89C5131 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.
