Renesas Technology Corp. has released its SH7720 32-bit SuperH RISC microprocessor that features on-chip SSL accelerator and comprehensive on-chip peripheral functions such as color LCD controller and USB.

A functionally enhanced version of the SH7727, the device is suitable for use in IT terminals equipped with a secure and smooth browser display function, enabling fast and easy development of sophisticated products.

The SH7720 incorporates a hardware accelerator compatible with SSL (browser protocol provided with security functions). The accelerator is a hardware circuit that performs RSA encryption public key and private key processing, and common key encryption/decryption processing in DES/3DES encryption.

A full range of on-chip peripheral functions is provided, including a color LCD controller, USB Host and Function, and a CompactFlash (CF) memory card interface, and a newly added MultiMediaCard (MMC) interface, I?C bus interface, and IrDA interface (v1.0 support).

The SH7720 has an SH3-DSP CPU core with a maximum operating frequency of 133MHz, and achieves high processing performance of 173MIPS. This makes it possible to implement high-speed communication processing, while an on-chip DSP supports various kinds of middleware, such as a voice codec and echo canceller required by VoIP, and JPEG processing for still-image display.

Employing a 0.15?m CMOS process, the product achieves reduced power consumption through the use of special on-chip memory control circuit techniques.

The 17-by-17mm 256-pin CSP employs a pin arrangement with I/O power supply pins outermost pins and the CPU core power supply innermost. A smaller 11-by-11mm 256-pin CSP is also available for use in compact IT terminal devices.
