GENERAL DESCRIPTION
The Teridian Semiconductor Corporation 73S1217F is a
versatile and economical CMOS System-on-Chip device
intended for smart card reader applications. The circuit
features an ISO-7816 / EMV interface, an USB 2.0
interface (full-speed 12Mbps - slave) and a 5x6 PINpad
interface. Additional features include 8 user I/Os,
multiple interrupt options and an analog voltage input (for
DC voltage monitoring such as battery level detection).
Other built-in interfaces include an asynchronous serial
and an I2C interface.
The System-on-Chip is built around an 80515 high-
performance core. Its feature and instruction set is
compatible with the industry standard 8051, while
offering one clock-cycle per instruction processing
power (most instructions). With a CPU clock running up
to 24MHz, it results in up to 20MIPS available that
meets the requirements of various encryption needs
such as AES, DES / 3-DES and even RSA (for PIN
encryption for instance). The circuit requires a single 6
to 12 MHz crystal. An optional 32kHz crystal can be
connected to a sub-system oscillator with a real-time-
clock counter to enable stand-alone applications to
access an RTC value.
The respective 73S1217F embedded memories are;
64KB Flash program memory, 2KB user XRAM
memory, and 256B IRAM memory. On top of these
memories are added independent FIFOs dedicated to
the ISO7816 UART and to the USB interface.
The chip incorporates an inductor-based DC-DC
converter that generates all the necessary voltages to
the various 73S1217F function blocks (smart card
interface, digital core, etc.) from any of two distinct
power supply sources: The +5V USB bus (VBUS, 4.4V to
6.5V), or a main battery (VBAT, 4.0V to 6.5V). The chip
automatically powers-up the DC-DC converter with VBUS
if it is present, or uses VBAT as the supply input.
Alternatively, the pin VPC can support a wider power
supply input range (2.7V to 6.5V), when using a single
system supply source.
In addition, the circuit features an ON/OFF mode which
operates directly with an ON/OFF system switch: Any
activity on the ON/OFF button is debounced internally
and controls the power generation circuit accordingly,
under the supervision of the firmware (OFF request /
OFF acknowledgement at firmware level). The OFF
mode can be alternatively initiated from the controller
(firmware action instead of ON/OFF switch).
In OFF mode, the circuit typically draws less than 1μA,
which makes it ideal for applications where battery life
must be maximized.
Wake-up of the controller upon USB cable insertion is
supported.
Embedded Flash memory is in-system programmable
and lockable by means of on-silicon fuses. This makes
the Teridian 73S1217F suitable for both development and
production phases.
Teridian Semiconductor Corporation offers with its
73S1217F a very comprehensive set of software libraries,
including the smart card and USB protocol layers that are
pre-approved against USB, Microsoft WHQL and EMV,
as well as a CCID reference design. Refer to the
Teridian Semiconductor Corporation 73S12xxF Software
User’s Guide for a complete description of the Application
Programming Interface (API Libraries) and related
Software modules.
A complete array of development and programming
tools, libraries and demonstration boards enable
rapid development and certification of readers that
meet most demanding smart card standards.

Program Memory: The 80515 can address up to 64KB of program memory space from 0x0000 to
0xFFFF. Program memory is read when the MPU fetches instructions or performs a MOVC operation.
After reset, the MPU starts program execution from location 0x0000. The lower part of the program
memory includes reset and interrupt vectors. The interrupt vectors are spaced at 8-byte intervals, starting
from 0x0003. Reset is located at 0x0000.
Flash Memory: The program memory consists of flash memory. The flash memory is intended to
primarily contain MPU program code. Flash erasure is initiated by writing a specific data pattern to
specific SFR registers in the proper sequence. These special pattern/sequence requirements prevent
inadvertent erasure of the flash memory.
The mass erase sequence is:
1. Write 1 to the FLSH_MEEN bit in the FLSHCTL register (SFR address 0xB2[1]).
2. Write pattern 0xAA to ERASE (SFR address 0x94)
Note: The mass erase cycle can only be initiated when the ICE port is enabled.
The page erase sequence is:
1. Write the page address to PGADDR (SFR address 0xB7[7:1])
2. Write pattern 0x55 to ERASE (SFR address 0x94)
The PGADDR register denotes the page address for page erase. The page size is 512 (200h) bytes and
there are 128 pages within the flash memory. The PGADDR denotes the upper seven bits of the flash
memory address such that bit 7:1 of the PGADDR corresponds to bit 15:9 of the flash memory address.
Bit 0 of the PGADDR is not used and is ignored. The MPU may write to the flash memory. This is one of
the non-volatile storage options available to the user. The FLSHCTL SFR bit FLSH_PWE (flash program
write enable) differentiates 80515 data store instructions (MOVX@DPTR,A) between Flash and XRAM
writes. Before setting FLSH_PWE, all interrupts need to be disabled by setting EAL = 1. Table 3 shows
the location and description of the 73S1217F flash-specific SFRs.
Any flash modifications must set the CPUCLK to operate at 3.6923 MHz (MPUCLKCtl = 0x0C)
before any flash memory operations are executed to insure the proper timing when modifying the
flash memory.
