Description

is a high-performance CMOS derivative of the 80C51 8-bit microcontrollers optimized for USB keyboard with smart card reader applications. AT8xC5122 retains the features of the Atmel 80C51 with 32 Kbytes 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, AT8xC5122 has a USB 2.0 full-speed function controller with seven Endpoints, a multi-protocol smart card interface, a dual data pointer, seven programmable LED current sources (2-4-10 mA) and a hardware watchdog. AT8xC5122 Flash RAM version and AT8xC5122 Code RAM version with 32 Kbytes memory can be loaded by In-System Programming (ISP) software residing in the onchip ROM from USB or UART. AT8xC5122 have 2 software-selectable modes of reduced activity for further reduction in power consumption. is a low pin count of the AT8xC5122. This version doesn't have the keyboard and the SPI interfaces. The PLCC28 packages for AT8xC5122 and AT8xC5123 have the same pinout. The AT8xC5123 is also proposed a VQFP32 package. AT8xC5122 and AT8xC5123 are proposed with a 512 bytes EEPROM (AT24C04) and
