Product Overview:

With a high-speed 16-bit RS-4 CPU core upward compatible with AE-3/AE4, and EEPROM, ROM, RAM, two I/O ports, a random number generator (RNG), a watchdog timer (WDT), a UART compliant with ISO/IEC 7816-3, a 16-bit interval timer (TMR), an internal clock oscillator, a CRC coprocessor, a triple DES coprocessor, and a modular multiplication coprocessor as built-in standards.
With a lineup of products incorporating functions such as AES Coprocessor, ISO/IEC14443-A, B and FeliCa* specification contactless interface, the RS-4 Series finds application in the building of high-level security systems across a wide range of fields.
