Hardware Overview
The 73S1210F single smart card controller integrates all primary functional blocks required to implement
a smart card reader. Included on chip are an 8051-compatible microprocessor (MPU) which executes up
to one instruction per clock cycle (80515), a fully integrated IS0 7816 compliant smart card interface,
expansion smart card interface, serial interface, I2C interface, 6 x 5 keypad interface, RAM, FLASH
memory, and a variety of I/O pins.
The power management circuitry provides a 3.3V voltage output (VDD, pin #68) that must be connected
to the power supply inputs of the digital core of the circuit, pins # 28 and 40 (these are not internally
connected). Should external circuitry require a 3.3V digital power supply, the VDD output is capable of
supplying additional current.
Figure 1 shows a functional block diagram of the 73S1210F.

80515 MPU Core
1.3.1
80515 Overview
The 73S1210F includes an 80515 MPU (8-bit, 8051-compatible) that performs most instructions in one
clock cycle. The 80515 architecture eliminates redundant bus states and implements parallel execution
of fetch and execution phases. Normally a machine cycle is aligned with a memory fetch, therefore, most
of the 1-byte instructions are performed in a single cycle. This leads to an 8x performance (average)
improvement (in terms of MIPS) over the Intel 8051 device running at the same clock frequency.
Actual processor clocking speed can be adjusted to the total processing demand of the application
(cryptographic calculations, key management, memory management, and I/O management) using the
XRAM special function register MPUCKCtl.
Typical smart card, serial, keyboard and I2C management functions are available for the MPU as part of
the Teridian standard library. A standard ANSI “C” 80515-application programming interface library is
available to help reduce design cycle. Refer to the 73S12xxF Software User’s Guide.
1.3.2
Memory Organization
The 80515 MPU core incorporates the Harvard architecture with separate code and data spaces.
Memory organization in the 80515 is similar to that of the industry standard 8051. There are three
memory areas: Program memory (Flash), external data memory (XRAM), and internal data memory
(IRAM). Data bus address space is allocated to on-chip memory as shown Table 2

Note: The IRAM is part of the core and is addressed differently.
Program Memory: The 80515 can address up to 32KB 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
