1. Description
AT89C5130A/31A-M is a high-performance Flash version of the 80C51 single-chip 8-bit micro-
controllers with full speed USB functions.
AT89C5130A/31A-M 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 recov-
ery. USB Event detection logic (Reset and Suspend/Resume) and FIFO buffers supporting the

(EP1/EP2/EP3/EP4/EP5/EP6) with minimum software overhead are also part of the USB
module.
AT89C5130A/31A-M retains the features of the Atmel 80C52 with extended Flash capacity
(16/32-Kbytes), 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, AT89C5130A/31A-M 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 pro-
grammable LED current sources, a programmable hardware watchdog and a power-on reset.
AT89C5130A/31A-M 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 periph-
eral clock is frozen, but the device has full wake-up capability through USB events or external
interrupts.
