AE3 Series High Security 8-bit Smart Card Microcontroller Features AE330 AE330 AE340 AE340 AE350 AE350 8.25kbytes EEPROM; 24kbytes ROM; 512bytes RAM 16.5kbytes EEPROM; 46kbytes ROM; 1280bytes RAM 32.5kbytes EEPROM; 48kbytes ROM; 3kbytes RAM Integrated Security Concept (ISC) As with every Smart Card microcontroller from Hitachi, the AE3xx series has been designed with the most demanding of security conscious applications in mind. The design includes many safeguards to ensure that the devices only operate in the way intended. For example, a distributed lay out for a critical area makes physical attack methods more difficult. An illegal address detector ensures that only valid memory addresses can be accessed, a hardware Random Number Generator (RNG) provides inputs for key generation and software randomisation techniques, and a Watchdog Timer (WDT) protects against software runaway. The AE3xx series has many other advanced security features to protect it against attacks and system faults. For example, it contains hardware features specifically designed to protect data processing on the device from power analysis attacks (such as SPA/DPA). Uniquely, Hitachi devices are fabricated using a MONOS (Metal Oxide Nitride Oxide Silicon) EEPROM structure. This is significantly more resistant to radiation disturbance than standard EEPROM structures. This design feature further protects the data on the device from illegal or accidental alteration. Applications The AE3xx series fulfils the requirements of all Smart Card applications with high memory demand, such as GSM- SIM cards, electronic banking, multi-application cards, and access control. For GSM-SIM cards the large EEPROM available on the AE3xx means it can support many of the advanced applications which will be delivered by communications service providers. These include SIM Application Toolkit (SAT), Wireless Application Protocol (WAP). The SAT in today's GSM-SIM card standard allows network operators to offer value-added services to the end-users of mobile phones. These applications can include, for example, up-to-date traffic, weather or sports information as well as stock market data, all of which can be utilised using the AE3xx series. WAP allows Internet-like access to information, data access, and the ability to use e-mail via a mobile phone. The memory configuration of AE3xx series can be used to store additional information on a SIM card such as e-mail addresses. The AE3xx series is a high security Smart Card microcontroller fabricated in 0.35µm CMOS technology and built around the high-speed 8/16-bit H8 CPU core. Operating at a maximum of 10MHz external clock rate at 5V, the AE3xx series rapidly executes bit manipulation instructions, arithmetic and logic instructions, and data transfer instructions.
