The M32C/90 series, the top of the range in the M16C family, comprise 32-bit CISC microcontrollers for automotive and industrial applications. The first product release consists of four 64MHz models in the M32C/95 group, which deliver twice the speed and more functionality than chips in the current M32C/80 series.

The new devices maintain the key advantages of the M16C family: highly efficient C language support, strong noise immunity, low noise emissions, and low power consumption. To improve processing performance, their high-performance M32C/90 CPU core has new features, including a 32-bit arithmetic circuit, transfer instructions, and a barrel shifter for shift instructions.

The microcontrollers provide a three-channel CAN controller. One channel of this controller supports 32 message slots, while the other two support 16 message slots. An on-chip non-stop debugging interface connects to an external debugger via a single unused pin. The devices' many other peripheral functions include 16-bit timers, DMAC, and A/D and D/A converters. Seven serial I/O channels provide LIN master support for systems equipped with communication functions. The two flash memory options are available: 768KB and 512KB. Development support includes the single-line non-stop debugger. The devices have 100-pin LQFP or 144-pin LQFP packages.

The SH7619, which expands the SuperH family, is a 32-bit microprocessor with an internal Ethernet PHY (physical layer) transceiver and Ethernet controller. It is an excellent choice for digital AV products, OA machines, and FA equipment that require a network connection function.

The new chip is the first Renesas microprocessor to incorporate both a media access controller (MAC) that complies with the IEEE-802.3 standard and a PHY transceiver on a single chip. (Previously the PHY was a separate component.) Thus, the SH7619 simplifies the development of 10/100Mbps Ethernet LAN connection functions and reduces the system component count. The chip's SH-2 CPU core has a maximum operating frequency of 125MHz and is suitable for the high-speed processing of TCP/IP and other protocols.

The microprocessor also includes a host interface function (HIF) for connecting to other microprocessors. An on-chip debug function supports real-time debugging at the chip’s maximum operating frequency. Development tools include the E10A-USB emulator. The SH7619 is packaged in a small (13mm x 13mm) 176-pin BGA.

The HAT2210WP power MOSFET enables the design of smaller DC/DC converters for notebook PCs, communication equipment, and many other types of products. The device contains two MOSFETs in a 5.3mm x 6.1mm package with a slim (0.8mm, max.) WPAK housing (Renesas profile code) that achieves high heat dissipation.

Heat generated by the power MOSFETS is transferred very efficiently to the circuit board from the heat-dissipating die pad on the under side of the device. In fact, the thermal resistance of the WPAK profile package is half that of the SOP-8 profile package used by the previous HAT2210R MOSFET device. As a result, the new HAT2210WP device can safely control one and a half times as much output current. System engineers can take advantage of this performance to reduce the number of MOSFETs in DC/DC converters that handle higher currents.

Also, because the HAT2210WP includes separate high-side and low-side transistors, it has separate drain connections. Both of the power MOSFETs are eighth-generation designs built with Renesas' latest industry-leading 0.35?m process. The optimized design of this power device emphasizes switching speed for the high-side transistor and low on-resistance for the low-side transistor. This makes it possible to obtain higher efficiency for the low-voltage side of the DC/DC converter.

The SH-Mobile application processor has been selected for use in a GSM/EDGE handset produced by LG Electronics Corporation now on sale in the United States. (EDGE = Enhanced Data Rates for GSM Evolution, an enhanced data transfer technology based on GSM). Thus, there are now six different mobile phone models made by LG Electronics that use SH-Mobile devices, including a CDMA handset and a GSM/GPRS handset released since July 2004.

In the Japanese market, Renesas SH-Mobile chips have also been selected for the SH901iC (made by Sharp Corporation), the F901iC (made by Fujitsu Corporation), and the D901i (made by Mitsubishi Electric Corporation) ? three 901i Series-3 handsets for the NTT DoCoMo third-generation FOMA mobile phone service. These new handsets have been released progressively since December 2004. They provide long battery life: up to 570 hours of continuous standby operation (static) and 160 minutes of continuous communication time. Other features include a 260,000-color QVGA main color display, a 204Megapixel (max.) auto-focus digital camera function, and a seamless TV telephone function.
