The 700 MHz ARM11 MPCore multicore processor is scheduled to be available for SoC integration before the end of 2007 in the CB-90M IP library. Both processors are available for either cell-based IC (CB-IC) or customer-owned tooling (COT) applications.
Renesas Technology has announced commercialization of 30 new products in seven groups as part of the R8C/Tiny Series of compact, high-performance 16-bit MCUs with on-chip Flash memory. Designed for applications such as power supply control and motor control, the R8C/2E, R8C/2F, R8C/2G, R8C/2K, and R8C/2L Groups have 32-pin packages, while the R8C/2H and R8C/2J have 20-pin packages. Sample shipments began on August 28, 2007 in Japan.
The addition of the 30 new products will bring the total number of products in the R8C/Tiny Series to 268.
The R8C/2E and R8C/2F groups are the first 32-pin R8C/Tiny Series products to incorporate a D/A converter (8-bit x 2 channels) and comparator (2 channels) adding to a 12-channel A/D converter. They provide rich analog peripheral functions, and their low pin count and compact 32-pin packages make them suitable for a wide range of analog data processing functions. These groups support power supply voltages from 3.0V to 5.5V and have a maximum operating frequency of 20 MHz.
The R8C/2G, R8C/2H, and R8C/2J groups are versions of existing R8C/Tiny Series products with peripheral functions reduced. This increases the number of options available to customers wishing to select MCUs for their systems that make good use of functions. In addition, these MCUs incorporate a voltage detection circuit with a comparator mode. This enables monitoring of the power supply voltage or digital output of external input voltage comparison results. These groups support power supply voltages from 2.7V to 5.5V and have a maximum operating frequency of 8 MHz.
The R8C/2K and R8C/2L groups are 32-pin products with timer functions suitable for motor control applications. The 3-channel 16-bit timer has an input capture/output compare function. A single MCU can handle both 3-phase PWM output and 3-phase pulse input for control of brushless DC motors, etc. These groups support power supply voltages from 3.0V to 5.5V and have a maximum operating frequency of 20 MHz.
Available development environments include the E8a emulator, which supports on-chip debugging via a 1-pin interface, and the existing E8 emulator. Both emulators connect via a single pin, so all I/O pins remain available for use during debugging. In addition, both the above emulators can be used as a Flash memory writer.
Renesas Technology has announced the development of the 32-bit SuperH Family SH72546RFCC as the industry's first microcontroller with on-chip Flash memory to use a 90 nm process. Sample shipments will begin in October 2007 in Japan.
The SH72546RFCC achieves an operating speed of 200 MHz in a high-temperature environment with an operating ambient temperature of 125 degrees C required for automotive applications. Together with other architectural improvements this increases performance by more than 4 -fold compared to earlier SuperH offerings.
The SH72546RFCC incorporates a high-performance SH-2A CPU core employing superscalar design and a Harvard architecture. The use of a 90 nm process has made it possible to provide on-chip Flash memory with a 3.75 MByte capacity. In addition, 128 kBytes of on-chip Flash memory with virtually equivalent to EEPROM functions are provided for data storage, eliminating the need for external EEPROMs. In the SH72546RFCC, higher Flash memory access speed has been achieved through the use of proprietary Renesas technology, and performance virtually equivalent to 1-cycle access at 200 MHz has been attained through the implementation of a cache circuit.
The SH72546RFCC incorporates a comprehensive set of functions suitable for engine and transmission control. Among the peripheral functions and interfaces provided on chip are a multifunction timer unit (ATU-III: Advanced Timer Unit III) useful for engine and transmission control, a high-speed 12-bit A/D converter, a CAN interface, and an SPI, enabling both high-precision real-time control and small-area mounting to be achieved.
Large-capacity on-chip emulation RAM is provided separately from the user RAM as a function specifically for program development use. This RAM overlaps the Flash memory area, and allows real-time adjustment of application program control parameters while data are rewritten as desired during microcontroller operation. Debugging functions such as an Advanced User Debugger are also included that help to improve the efficiency of user program development.
The package used is a 272-pin P-BGA (21 mm x 21 mm). Available development tools include the USB bus-powered E10A-USB on-chip debugging emulator requiring no external power supply, and the E200F full-spec emulator.
Renesas has announced the development of the H8SX/1700 Series, featuring a maximum operating frequency of 80 MHz, as a new in-vehicle control system oriented series in the H8SX Family of microcontrollers incorporating an H8SX 32-bit CISC CPU core. Sample shipments will begin in October 2007 in Japan.
The H8SX/1725F employs a 150 nm CMOS process and has 256 kBytes of on-chip Flash memory for program storage use. It is high-speed Flash memory capable of 1-cycle access at 100 MHz. The Flash memory can be programmed on board.
In addition, 16 kBytes on-chip data Flash is provided for data storage use, offering a maximum of 480,000 program and erasure, and a guaranteed 15-year data retention period. It can be used to replace previously used external EEPROM in a system, enabling cost reductions to be achieved through the use of fewer parts.
The H8SX/1725F is also equipped with a comprehensive set of on-chip peripheral functions suitable for use in in-vehicle control systems. A high-speed serial interface that enables high-speed communication with other chips is included, allowing maximum 32-bit length data communication at a maximum communication frequency of 10 MHz, while the provision of a 4-stage 32-bit data buffer allows 4 frames of data to be stored at one time, for implementation of easy-to-use functions. Moreover, the CPU load can be greatly reduced through combined use with a DMAC or DTC.
Other examples of the comprehensive set of functions suitable for in-vehicle control system use include a 2-channel module supporting communication via a CAN, the virtually de facto industry standard in-vehicle LAN, a 2-channel serial communication module, a hardware LIN, and a 12-channel 16-bit timer (TPU).
The package used is a small 100-pin LQFP (14 mm x 14 mm).
The new ST7LITE49M series, available in an LQFP32 package for mass production and in SDIP32 for prototyping, will enlarge the Lite family by offering small-memory MCUs, up to 4 kBytes, with up to 24 high-sink-current I/O lines and 128 Bytes of true EEPROM Memory on board.
A powerful timer set is integrated on the chip, including a configurable watchdog timer, dual 8-bit timers with prescaler, and dual 12-bit Auto-Reload timers, which operate over the 250 Hz to 4 MHz range and provide four PWM signals with output compare function, input capture, dead-time generation, and one-pulse mode. In particular, the 12-bit timer is specifically optimized for lighting and motor control applications, such as in e-bikes or air conditioning.
Other on-chip functions include a precise internal 8 MHz RC oscillator, 32 kHz auto-wake up oscillator, a 10-channel 10-bit ADC, five power saving modes, and a trimmable Reset circuit with low voltage detection. In addition, an I2C communication interface is integrated on chip.
The ST7LITE49M is available now in SDIP (samples) and LQFP32 (volume) packages, priced at $0.78 in quantities of 10,000 pieces.
