Description
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 specifica-
tions 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.
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 reduc-
tion 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.
