AE-5 Series 32-Bit Smart Card Microcontroller Offers Four Times The Performance Of The AE-4 Series


SAN JOSE, Calif., TOKYO and LONDON, - November 17, 2003 - Renesas Technology Corp. today announced the first product from its AE-5 Series of 32-bit smart card microcontrollers. The AE57C offers approximately four times the performance of the AE-4 Series and 132 Kbyte (KB) of EEPROM, the largest memory capacity of any of the company's smart card microcontrollers. It also features 320 KB of mask ROM and supports the latest AES (Advanced Encryption Standard) encryption processing. The device is suitable for multi-function, large capacity smart cards such as USIM cards for third generation mobile phone and multi-application cards.

The AE57C uses the AE-5 CPU core which has a 32-bit arithmetic-logic unit (ALU) and internal bus width. The core is upward-compatible with the AE-4 16-bit CPU, enabling AE-4 Series programs to be used, but offers approximately four times the processing performance as it executes one instruction per cycle instead of one instruction in two cycles. It also features new instructions and addressing modes. ROM code efficiency has been improved by approximately 20% compared with the AE-4, enabling programs to be made more compact.

The device's large memory capacity enables the storage of multiple applications and large volumes of data, meeting the requirements of multi-function smart cards. It uses Renesas Technology's well-established proprietary MONOS (Metal Oxide Nitride Oxide Silicon) EEPROM, ensuring high reliability. The mask ROM allows the storage of a large general purpose operating system to perform complex processing as well as the storage of application programs and data that do not require rewriting. This enables the EEPROM capacity to be used to the full.

In addition to the peripheral functions of the AE-4 Series, the device features a BEM (Bytecode Extension Module). This is a function for fetching bytecode and executing conversion to user-defined execution addresses, enabling processing by a Java Card(TM) or MULTOS(TM), for example, to be made simpler and faster. The device also offers a DMAC (Direct Memory Access Controller) that supports high speed communications, reducing the load on the CPU, an AES coprocessor that executes the latest encryption processing, and two I/O ports incorporating a UART for full-duplex communications. The on-chip exponential multiplication/division algorithm coprocessor has been extended to 2112 bit capability and enhanced to provide greater security and improved performance.

The E6000H full emulator and SE-I simple emulator are available as development tools. The AE57C can be shipped in wafer or COT (Chip On Tape) form. Sample shipments will begin in February 2004.
