FUNCTIONAL DESCRIPTION
Throughout this specification, it is assumed that the reader
is aware of ISO7816 norm terminology.
8.1
Microcontroller
The embedded microcontroller is an 80C51FB with
internal 16 kbytes ROM, 256 bytes RAM and 512 bytes
XRAM. It has the same instruction set as the 80C51.
The controller is clocked by the frequency present on pin
XTAL1.
The controller may be reset by an active HIGH signal on
pinRESET,butitisalsoresetbythePower-onresetsignal
generated by the supply supervisor.
The external interrupt INT0_N is used by the ISO UART,
by the analog drivers and the ETU counters. It must be left
open in the application.
The second external interrupt INT1_N is available for the
application.
A general description as well as added features are
described in this chapter.
The added features to the 80C51 controller are similar to
the 8XC51FB controller, except on the wake-up from
Power-down mode, which is possible by a falling edge on
INT0_N (card reader problem) or on INT1_N or on RX due
to the addition of an extra delay counter and enable
configuration bits within register UCR2 (see detailed
description in Section 8.10.3.2). For any further
information please refer to the published specification of
the8XC51FBin“DataHandbookIC20;80C51-Based8-bit
Microcontrollers”
The controller has four 8-bit I/O ports, three 16-bit
timer/event counters, a multi-source, four-priority-level,
nestedinterruptstructure,anenhancedUARTandon-chip
oscillator and timing circuits. For systems that require
extra memory capability up to 64 kbytes, it can be
expanded using standard TTL-compatible memories and
logic.
