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.
It supports GSM phase 2+ and GPRS Class 12 operation, and offers a simple upgrade to Edge implementations.
"This move into baseband technology is made possible by our extensive market and design experience", said Chris Litchfield, Manager of Hitachi Europe's Mobile Business Segment.
"The launch of THAMIS completes Hitachi's product range for GSM and next generation mobile handsets, consolidating our position as a key systems supplier for the wireless industry".

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.
Hitachi's GSM system solution includes baseband (THAMIS), RF linear, HPA, SAW-based front-end modules, memory (Flash, SRAM and stacked devices), LCDs and controllers, power management devices, SIM cards and reference design support.
"We more or less provide everything except the plastic", added Litchfield.
"This will benefit our customers by reducing the number of suppliers they need to talk to, saving them time and money".
THAMIS is composed of two baseband chips, the digital THAMIS mobile control processor (T-MCP1), and the mixed-signal THAMIS analogue front end (T-AFE1).
In contrast with the more traditional separation of CPU and DSP, the T-MCP1 processing engine, fabricated in 0.18mm CMOS, uses two powerful SH-DSP cores: the applications core, which operates at up to 52MHz and provides enough processing power to run the value add applications required in today's handsets; and the communications core, which runs at 104MHz (max), sufficient for class 12 multislot GPRS and EDGE systems.
Both cores offer RISC and DSP functionality, allowing new software partitioning options that can be useful when applications space is limited.
The low power 0.35mm T-AFE1 features all the necessary interfaces to support a wide range of radio transceivers, including Hitachi's market proven HD1551xx series.
Its design incorporates both the Edge and standard GMSK modulators.
The chipset enables a standby time of more than 600h on a standard lithium battery and features dual SIM support, MP3 replay and MMC compatibility.
A comprehensive debug toolset is available for use with both cores.
THAMIS and its accompanying layer 1 software have been developed jointly by Hitachi and TTPCom.
This ensures that THAMIS will support the industry standard GSM/GPRS protocol software and applications from TTPCom.
Hitachi and TTPCom together offer support for customers' type approval programs, based on evaluation and reference platforms and software which have already been tested to GCF (GSM Certification Forum) standards.
This means that customers can start designing THAMIS based systems secure in the knowledge that they are using a proven solution.
