AT83EC5123 概述
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 volatile
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 program
memory access mode is disabled.
