3 / 213 page  3 AT8xC5122/23 4202D–SCR–06/05 Product Description AT8xC5122/23 products are high-performance CMOS derivatives of the 80C51 8-bit microcontrollers designed for USB smart card reader applications. The AT8xC5122 is proposed in four versions : - ROM version with or without internal data E2PROM. The ROM device is only factory programmable. - CRAM version without internal data E2PROM. The CRAM device implements a vola- tile program memory which is programmed by means of an embedded ROMed bootloader which transfers the code from a remote software programming tool called FLIP through UART or USB interfaces. - Flash version without internal data E2PROM. At power-up, the program located in the flash memory is transferred into the CRAM then executed. The AT83C5123 is a low pin count of the AT8xC5122 and is proposed in ROM version with or without internal data E2PROM. The ROM device is only factory programmable. The AT8xC5122DS is a secure version of the AT8xC5122 on which the external pro- gram memory access mode is disabled. |
