Development Tools * Voyager Emulation Platform (ATV4 Standard) to Support Software Development * IAR Systems EWAVR(R) V4.21A Debugger or Above * Software Libraries and Application Notes Description The AT90SC25672RCT-USB is a low-power, high-performance, 8/16-bit microcontroller with ROM program memory, EEPROM data memory, cryptographic accelerator based on the secureAVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the AT90SC25672RCT-USB achieves throughputs close to 1 MIPS per MHz. Its Harvard architecture includes 32 general purpose working registers directly connected to the ALU, allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The AT90SC25672RCT-USB uses a new AVR(R) 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 encryption 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-system. This technology combined with the versatile 8/16-bit CPU on a monolithic chip provides a highly flexible and cost-effective solution to many smart card applications. Additional security features include power and frequency protection logic, logical scrambling on program data and addresses, Power Analysis countermeasures and memory accesses controlled by a supervisor mode. A block diagram of the AT90SC25672RCT-USB is shown in Figure 1 hereafter. USB Controller Description The AT90SC25672RCT-USB features an USB V2.0 Full Speed controller which requires a 48 MHz external crystal 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 serialparallel data conversion. The UFI connects the USB interface to the AVR. It consists of a protocol engine and provides five configurable data transfer endpoints, each with its own DPRAM in the memory area. The data transfer type for each endpoint is configured by software. The table below indicates the characteristics of each endpoint: Table 1: Characteristics of each endpoint. Endpoint number Size (bytes) Available data transfer modes EP0 64 BULK, ISOCHRONOUS, INTERRUPT, CONTROL EP1 2 * 64 BULK, ISOCHRONOUS, INTERRUPT EP2 2 * 64 BULK, ISOCHRONOUS, INTERRUPT EP3 64 BULK, ISOCHRONOUS, INTERRUPT, CONTROL EP4 64 BULK, ISOCHRONOUS, INTERRUPT, CONTROL 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. 2 AT90SC25672RCT-USB 6522DS-SPD-07Sep07 AT90SC25672RCT-USB Figure 1.
