This allows to use AT89C5130A for development, pre-production and flexibility, while using
AT83C5134/35 for cost reduction in mass production. Similarly AT83C5136 is pin compatible
with AT89C5131A 32-Kbytes Flash microcontroller.
AT83C5134/35/36 features a full-speed USB module compatible with the USB specifications
Version 2.0. This module integrates the USB transceivers 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
5 versatile Endpoints (EP1/EP2/EP3/EP4/EP5) with minimum software overhead are also part of
the USB module.
AT83C5134/35/36 retains the features of the Atmel 80C52 with extended ROM cpacity (8/16/32
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, AT83C5134/35/36 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.
AT83C5134/35/36 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.
