8-bit Flash Microcontroller with Full Speed USB Device

Atmel Corporation 

Description

AT89C5130A/31A-M is a high-performance Flash version of the 80C51 single-chip 8-bit

microcontrollers with full speed USB functions.

AT89C5130A/31A-M features a full-speed USB module compatible with the USB speci-

fications 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.

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 programmable 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 peripheral clock is frozen, but the device has full wake-up capability

through USB events or external interrupts.
