Renesas Electronics Corporation Unveils RH850/P1x Series of Microcontrollers
Oct 17 14
Renesas Electronics Corporation has unveiled RH850/P1x series of microcontrollers, or MCUs. The RH850/P1x Series of 32-bit MCUs features the world's first automotive chassis MCUs that utilize a 40nm process. Combining the 40nm process with its unique MONOS flash memory structure, Renesas offers an innovative solution for electrical power steering (EPS), brake systems, and other chassis systems, delivering reduced power consumption, and more efficient functional safety system development in chassis systems. Designing for automotive safety is becoming more complex, particularly in chassis systems for mission-critical steering and braking control. In addition to the new RH850/P1x series, Renesas Electronics is developing a kit that combines an RH850/P1x Series MCU (single-power-supply version) and the RAA270005KFP power control IC to reduce the power supply design burden significantly. The power control IC integrates trackers for the power supply required by the RH850/P1x Series MCU (single-power-supply version) and for two external sensor power supplies, as well as a variety of monitoring and self-diagnostic functions. Key Features of the RH850/P1M MCUs include: 40 nm process and MONOS flash memory for lower power consumption and higher performance; fault-detection functions ideal for chassis systems; and full complement of peripheral functions for chassis systems. In addition to the cutting-edge 40 nm process, the use of Renesas-exclusive metal oxide nitride oxide silicon (MONOS) structure, which has an established track record in flash memory, makes possible fast data read performance alongside low power consumption (approximately half that of earlier Renesas products). This means that the use of a standard QFP package and a single power supply with integrated core voltage generation regulator is possible. Renesas is leveraging more than 10 years of experience delivering high-quality MCU solutions as well as accumulated knowhow from participation in global functional safety standardization activities to reduce the development and design burden on customers. Designed with chassis systems requiring a high fault-detection rate and short control cycles in mind, the RH850/P1x Series integrates an excellent set of fault-detection functions. The CPU employs a lockstep2 system. An error checking and correcting (ECC) function detects and corrects data errors affecting memory, such as flash memory. There are also fault-detection functions that allow system-level diagnostics of the timers, ADC, serial communication, and other modules. The built-in self-test (BIST) function detects faults affecting the fault-detection functions themselves. The error control module (ECM) allows users to manage error signal input from the various modules. Upon receiving an error signal the ECU, has a variety of options including, setting an error pin output, generating interrupts or the generation of resets, thereby helping to assure both safety and reliability concerns can be addressed. In addition to this array of diagnostic functions, the RH850/P1x Series can be used as part of a kit including a dedicated power control IC. This enables monitoring of power supplies external and internal to the MCU, and reset control in case of malfunction. The RH850/P1x Series incorporates two units of the TSG3 (Timer S Generation 3), an enhanced motor control timer designed to improve the motor control performance of chassis systems. For serial communication, it retains the CAN protocol engine of previous Renesas products and includes RS-CAN, which increases the number of transmit and receive message buffers while incorporating improvements that make the buffers easier to use. Finally, the widely adopted SENT and PSI5 are provided as digital interfaces for sensors.
Renesas Electronics Corporation Announces Expansion of its RX100 Series of Microcontrollers
Oct 6 14
Renesas Electronics Corporation has announced the expansion of its RX100 Series of microcontrollers, or MCUs. Changing user preferences are driving new design needs, and the new RX111 MCUs bring increased memory capacity options to meet the demands of these growing markets. With larger memory capacity and innovative True Low Power technology, the RX111 group of MCUs brings the required high-performance and ultra-low power capabilities at attractive price points, opening new opportunities to develop the next generation of applications for the Internet of Things. As the industry's first entry-level 32-bit MCU to offer True Low Power, USB 2.0 connectivity, digital signal processing capability, and multiple on-chip safety features, the RX111 group provides strong support for a variety of systems, particularly for the healthcare and building automation segments. With increased memory capacity, ranging from 256KB to 512KB of Flash Memory and up to 64KB of on-chip RAM, the new RX111 devices extend the high performance and ultra-low power that the RX100 Series of MCUs is known to deliver. Renesas True Low Power technology delivers flexible power management and optimum power consumption for all use cases. The expanded RX111 group maintains the same low power features of the existing RX111 devices, with three different run modes, three low-power modes, and a flexible clock system. For instance, the Low Power Fast Wakeup capability enables the new MCUs to operate at 100ÂµA/MHz in Run Mode and 430nA in software standby from which it can wake up in only 4.8Âµs. It integrates a Zero Wait State Flash with Erase/Write as low as 1.8V, 1KB erase block size and background operation, and offers erase times as low as 10ms per block. These features combine to extend the operating duration of battery-powered products such as portable devices or healthcare devices, making it possible to build low-power, fast-wakeup products. An ultra-fast wakeup time helps to minimize the amount of time spent in an awake mode, for example processing an ADC signal, and thereby maximize the amount of time the MCU can spend in sleep mode. Based on the Renesas RX CPU core, the RX100 Series of MCUs delivers high performance, ultra-low power, connectivity and DSP functionality in a general-purpose MCU. All RX100 devices feature 32MHz operating speeds and 1.56 Dhrystone MIPS (DMIPS)/MHz throughput, with power consumption as low as 64 ÂµA/DMIPS. The RX111 devices support multiple communications peripherals, including USB 2.0 host with battery charging, device and OTG, and the I2C, and SPI (serial peripheral interface) protocols. Analog functions include a 12-bit ADC (analog-to-digital converter) with internal voltage reference, an 8-bit DAC (digital-to-analog converter) and a temperature sensor. Other significant features include a motor control timer (MTU2) and hardware safety features to comply with safety standards, including Cyclic Redundancy Checks (CRCs), Clock Accuracy Circuit (CAC) and independent watch dog timer. The RX100 Series of MCUs is software compatible with the RX600 and RX200 Series, providing greater flexibility and an easy migration path to higher performance MCUs. For a quick development start, the RX111 MCUs are supported by a robust development tool environment from both Renesas and third-party tool vendors that make up the RX ecosystem. Renesas provides a comprehensive development ecosystem for the RX Family, including e2studio, a powerful Eclipse-based IDE, as well as compilers, debuggers, code generation tools, and flash programmers. In addition, the RX111 devices are supported by the IAR Embedded Workbench for Renesas RX compiler and integrated development environment (IDE). RTOS and middleware is available from third-party companies such as Micrium, Segger, CMX, Express Logic, RoweBots, and FreeRTOS. Extensive software examples and drivers are provided by Renesas, including the Firmware Integration Technology (hereinafter FIT) Drivers. FIT is a completely new concept that emphasizes the simplification of embedding peripheral function module drivers and improves the portability between RX MCUs.
