The security field requires security optimized MCUs. The 16-bit (RS-4 Series) and 32-bit (AE-5 Series) CPUs with instruction compatibility from Renesas have been developed to fulfil this need.
The AE-5 Series are single chip microcomputer units with (MCUs) built around the high-speed 32bit AE-5 CPU. EEPROM, ROM, RAM, 2 I/O Ports, Random Number Generator (RNG), Watchdog Timer (WDT) and DES Engine (DES) , Firewall Management Unit (FMU), UART in compliance with ISO/IEC 7816-3, Direct Memory Access Controller (DMAC), 16 bit Interval Timer (TMR), Phase-Locked Loop (PLL), and also Modular Multiplication Coprocessor (MMC) are featured as standard.
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, the RS-4 Series finds application in the building of high-level security systems across a wide range of fields.
