MCUs have a huge 32Kbyte of RAM on-chip
Hitachi Europe has announced the immediate availability of a new series of 16bit microcontrollers featuring 32Kbyte on-chip RAM - the first in the industry to do so.
Most integrated GSM RF transceiver so far
Hitachi has launched its most integrated GSM RF transceiver solution to date.
The SH7300 is based on the first SH-Mobile device, but boasts a range of new features including an MPEG-4 hardware accelerator for image processing.
This enables high-speed execution of processing on-chip, which in previous Hitachi products was handled by middleware, reducing CPU processing load to one fifth that of previous SH-Mobile products.
The new processor has an SH3-DSP CPU core operating at a frequency of 133MHz.

Circular beam is a bonus for red laser diodes
Hitachi has announced the MARU Beam Series of red laser diodes which offers the world's first circular beam with a 1.2 (typical) aspect ratio in the 635nm wavelength band.
It allows individual modules to be shut down according to the functions being used, enabling overall system power consumption to be reduced.
The new device features an SXGA camera compatible interface to support next-generation mobile phones equipped with videophone functions and a high-definition camera.
This allows large volumes of high-definition camera image data to be captured at high speed and then displayed using a variety of functions, including electronic zoom.
The processor enables short time-frame implementation of next-generation mobile phone systems with multimedia applications.
It can also enable rapid response to new application development needs or modifications made necessary by future service diversification and service content changes, while keeping development costs low.
The SH7300 provides a varied selection of middleware for speedy and efficient development of application software.
This includes moving-picture recording middleware that supports the MPEG-4 format and enables simultaneous recording and playback of moving-picture and audio data.
A video mail function can be developed simply by creating a user interface to call this middleware from an application program.
The moving-picture recording middleware also supports an after-recording function that allows audio to be added to previously stored moving-picture data, facilitating the development of extended video mail functions.
Application program development is simplified by the provision of a development platform on the SH7300.
This incorporates a variety of peripheral modules and interfaces necessary for next-generation mobile phones, including an interface to AND- and NAND-type Flash memories.
Also included is fast SDRAM capable of handling high-speed applications, as well as a keyboard, small QVGA size colour LCD panel and VGA size ultraminiature camera.
This enables easy and speedy development of various multimedia-oriented application programs.
The SH7300 is available in a small CSP-256 package (11 x 11 x 1.40mm, 0.5mm pin pitch).
Sample shipments will begin in December 2002.
