MCUs provide data acquisition system on a chip

CISC microcontrollers combine 50MHz maximum operating frequency, 50MIPS performance and comprehensive on-chip peripheral functions.

The latest additions to the Renesas H8SX family of 32bit CISC (complex instruction set computer) microcontrollers combine 50MHz maximum operating frequency, 50MIPS performance and comprehensive on-chip peripheral functions.

The enhanced H8SX/1622 family of MCUs offers a wide range of products ideal for varied systems in PCs and OA products, digital consumer, and industrial products fields.

There are also plans to expand the lineup to a total of 20 models with the addition of 5.0V products, on-chip USB products and others by the end of 2007.

These products offer compatibility with the current H8SX family, offering a flexible approach to system functional enhancements and version upgrades.

The H8SX/1622 implements 256Kbyte on-chip Flash memory with zero wait state access, and also includes a six-channel 16bit delta-sigma type A/D convertor capable of high-precision conversion of information from various kinds of sensors, including gyro-sensors and optical, positional, acceleration and sound sensors.

This enables these models to be used in a wide range of application areas, including digital consumer applications, robotics, car navigations, and digital still cameras.

These are the first products in the H8SX family to incorporate a delta-sigma type A/D convertor.

The conversion speed is up to twice as fast as in the current H8/300L series models incorporating a delta- sigma type A/D convertor, and resolution has been improved from 14 to 16bit, providing both high speed and high precision.

In addition to a standard 144-pin LQFP (low profile quad flat L-leaded package), the package lineup includes a small 145-pin LGA (9 x 9mm) in which the LSI pins are connected to lands arranged in a grid pattern on the rear surface of the package.

This enables a user to reduce the size of the board and mounting area in portable devices and the like.

In addition to the 16bit delta-sigma A/D convertor, a 10bit A/C convertor and 8bit D/A convertor are integrated, and 16bit timer pulse and programmable pulse generator units enable various kinds of user system timer and pulse control to be implemented by a single chip.

An 8bit timer input is now available as the clock source for the SCI (Serial Communication Interface) inherited from current products, allowing flexible transfer rates to be implemented, and on-chip memory of 256Kbyte Flash and 24Kbyte RAM is integrated.

Sample shipments will begin in June 2007.
