C51 Microcontroller with USB and Smart Card Reader Interfaces
Description

AT83C5123 and AT83EB5123 are high performance derivatives of the 80C51 8-bit microcontrollers optimized for USB Smart Card Reader applications. The devices retain the features of the Atmel 80C51 with 16K bytes ROM capacity, 768 bytes of internal RAM, a 4-level interrupt system, two 16-bit timer/counters (T0/T1), a full duplex enhanced UART (EUART) with baud rate generator (BRG) and an on-chip oscillator. In addition, they both have a USB 2.0 full speed function controller with four Endpoints, a multi protocol smart card interface, four programmable LED current sources (2-4-10 mA) and a hardware watchdog. Development of application is done with or AT89C5122. These versions allow code to be loaded by In-System Programming (ISP) software residing in the onchip ROM from USB or UART. The devices have 2 software-selectable modes of reduced activity for further reduction in power consumption.
