Multichip modules incorporate SuperH micro and synchronous DRAM

28 March 2001 DSP, Micros & Memory

Hitachi offers eight new models in its HJ94/93D/93 Series of multichip modules (MCMs). Each of the MCM models incorporates a high performance SuperH microprocessor and synchronous DRAM (SDRAM) in a single package, enabling the speedy development of smaller and more powerful systems. They are ideal for use in a wide range of applications, such as industrial and consumer products with an emphasis on portable devices.

This MCM series is capable of aiding the development of ultra small systems. This is due to the single package offering of high performance SuperH together with high speed SDRAM. The HJ945010BP model features an SH-4 and four 64 Mb SDRAMs in a BGA package size of just 31 x 31 mm. This means that the mounting area can be cut to approximately 1/6 that of previous implementations. In addition, the high speed bus offers a data transfer speed of 100 MHz between the SH-4 and memory, eliminating the need for high speed bus design.

Additional memory can be connected externally as required by the system configuration, allowing the system memory capacity to be increased while still maintaining a compact system size.

* The HJ94 Series incorporates a SH7750 microprocessor with an SH-4 CPU core that provides 200 MHz or 360 MIPS performance. This series is suitable for embedded applications such as Internet TV, image processing systems, graphics oriented applications and other operations that require a high performance CPU featuring excellent floating-point performance.

* The HJ930 Series has a 133 MHz SH7729 microprocessor with an SH3-0SP CPU core. The high speed audio, voice and image data compression/decompression capabilities of its OSP make it suitable for use in consumer multimedia devices with a built-in browser or network products, such as routers, with a built-in VoIP.

The HJ93 Series, incorporating a 133 MHz SH7709A microprocessor with an SH-3 CPU core, offers low power consumption that makes it ideal for portable information terminals such as handheld PCs.
