Description
AT8xC5122 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 End-
points, 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 on-
chip ROM from USB or UART.
AT8xC5122 have 2 software-selectable modes of reduced activity for further reduction
in power consumption.
AT8xC5123 is a low pin count of the AT8xC5122. This version doesnt have the key-
board and the SPI interfaces. The PLCC28 packages for AT8xC5122 and AT8xC5123
have the same pinout. The AT8xC5123 is also proposed in a VQFP32 package.
AT8xC5122 and AT8xC5123 are proposed with a 512 bytes EEPROM (AT24C04) and
respectively named AT8xEC5122 and AT8xEC5123.
