Description
The AT90SC256 72RCT-USB is a low-power, high-performance, 8/16-bit microcontroller with ROM program mem ory,
EEPROM data memory, cryptograph ic accelerator based on the secureAVR enhanced RISC architectu re. By executing
powerfu l instru ctions in a single clock cycl e, the AT90S C25672RC T-U SB achiev es throughp uts close to 1 MI PS per MHz .
Its Harvard architecture includes 32 general purpose working registers directly connected to the ALU, allowing two inde-
pendent registers to be accessed in one single instruction executed in one clock cycle.
The AT90SC2567 2RCT-USB u ses a new AVR® architecture, the secureAVR that allows the linear addressing of up to 8M
bytes of code and up to 16M bytes of data as well as a number of new functional and security features.
The cryptographic accelerator featured in this product is the AdvX, a 32-bit accelerator dedicated to performing fast encryp-
tion and authentication functions. It is combined with a 32K byte-ROM for a high-performance and secure crypto firmware.
The ability to map the EEPROM in the code space allows parts of the program memory to be reprogrammed in-sy stem.
This techn ology combin ed with the v ersatil e 8/16- bit CPU on a mo nolith ic chip pr ovid es a highly flexi ble and co st-e ffective
solution to many smart card applications.
Additional security features include power and frequency protection logic, logical scrambling on program data and
addres ses, Power Analysis counterm easure s and memor y accesses controlle d by a superv isor mode. A bl ock diag ram of
the AT90SC25672RCT-USB is shown in Figure 1 hereafter.
USB Controller Description
The AT90S C25672 RCT-USB feature s an U SB V2.0 Full Speed controlle r whi ch requi res a 4 8 MHz external crys tal for the
data transfer. The USB interface consists of a Serial Interface Engine (SIE) and a Universal Function Interface (UFI). The
SIE performs clock/data separation, NRZI encoding and decoding, bit stuffing, CRC generation and checking and serial-
parallel data conversion.
The UFI connects the USB interface to the A VR. It consists of a protocol engine and provides five configurable data transfer
endpoi nts, eac h with its o wn DPRA M in th e memo ry are a. The data trans fer ty pe for each endpo int i s confi gure d by soft-
ware. The table below indicates the characteristics of each endpoint:
A DMA controller allows a fast communication rate between the RAM of the CPU and the DPRAM.
The USB controller provides a dynamic pull-up attachment and detachment and a host detection mechanism. In addition, it
offers an automatic interface detection between the USB 2.0 and the ISO7816 port.
