Space-saving MCMs combine MPU, Flash and
RAM
Hitachi has two new series of multi-chip modules (MCMs) that offer a high-performance SuperH microprocessor together with Flash and either SDRAM or SRAM in a single compact package.

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.
They are designed for use in portable products such as digital cameras and PDAs.
The HJ93D1 and HJ931 series are based on the SH3-DSP CPU core (SH7729R) and the SH-3 CPU core (SH7709S) respectively, operating at a frequency of 100MHz.
Two 64Mbit SDRAMs are housed within the packages, which measure just 13 x 13mm, with a maximum height of 1.7mm.
The packages require the same mounting area as a single SH7729R chip scale package product, enabling a potential 60% reduction in mounting area when compared to system configurations employing three packages.
By eliminating the need for bus design between the SuperH core and memories, the new packages can simplify system design and reduce product development time for customers.
The shorter board wiring resulting from miniaturisation reduces the effects of EMI, allowing stable, high-speed operation to be achieved.
The timespan from finalisation of the MCM product specifications to receipt of samples can be as little as eight weeks.
This cuts development time to approximately one-sixth that currently required for Hitachi ASIC design (assuming the use of existing LSI chips).
The incorporation of user ASICs is also supported.
The high speed voice and image data compression/expansion processing capabilities of the DSP make the HJ93D1 series suitable for use in multimedia devices, as well as digital video cameras and digital still cameras.
The HJ931 series offers low power consumption, which is suited to portable information terminals such as handheld PCs and PDAs.
SuperH support tools are available as a development environment for the HJ93D1 and HJ931 series.
Shipment of sample models based on reference specifications will begin in November.
