Target of Evaluation Description

This part of the Security Target Lite [ST_Lite] describes the Target of Evaluation (TOE)

as an aid to the understanding of its security requirements and address the product

type, the intended usage and the general features of the TOE.

2.1

Product Type

The TOE is the single chip microcontroller unit to be used in a smartcard product,

independent of the physical interface and the way it is packaged. Specifically, the TOE

is the AT90SC6404RT device from the AVR ASL4 family of smartcard devices.

Generally, a smartcard product may include other optional elements (such as specific

hardware components, batteries, capacitors, antennae) but these are not in the scope

of this Security Target Lite.

The devices in the AVR ASL4 family are based on ATMEL's AVR RISC family of

single-chip microcontroller devices. The AVR RISC family, with designed-in security

features, is based on the industry-standard AVR RISC low-power HCMOS core and

gives access to the powerful instruction set of this widely used device. Different AVR

ASL4 family members offer various options. The AVR ASL4 family of devices are

designed in accordance with the ISO standard for integrated circuit cards (ISO 7816),

where appropriate.

Although the TOE evaluation is hardware only, the TOE requires embedded software

to test the device and demonstrate certain security characteristics during the

development phase. In the end-usage phase there will be no embedded test software

in the TOE. Test software will be downloaded into the device EEPROM and be fully

erased before devices leave the test environment. This test software is only used for

the testing phase of the TOE life cycle and is outwith the scope of the evaluation. Test

mode is disabled by wafer saw.

The TOE widely uses ATMEL high density non volatile memories: it features 64K bytes

of AVR ROM program memory, 4K bytes of EEPROM program/data memory, 2K bytes

of static RAM memory.

The EEPROM includes 64 bytes of One Time Programmable (OTP) memory (32 bytes

are byte-addressable; 32 bytes are bit-addressable) and a 192-byte bit-addressable

area.

The EEPROM contains both ATMEL and customer specific data.
