New high-performance microcontrollers in 64- and 48-pin packages from Renesas Electronics are now available from MSC.
The twelve new devices are particularly suited for compact and cost-sensitive industrial and consumer applications.
The MCUs are provided with 256KB, 384KB or 512KB flash memory and achieve up to 165DMIPS processing power at 100MHz operation. The devices offer a wide range of communication, timer and analogue peripherals including USB 2.0 full-speed channel (Host, Device and OTG), CAN interface, 12 A/D converter channels, a 10-bit D/A converter and a real-time clock (RTC).
The RX631 derivatives that come in a 64-pin LQFP package, provide a six-channel multi-function timer pulse unit 2 (MTU2) with a complementary six-phase PWM, a six-channel timer pulse unit (TPU), a four-channel compare match timer (CMT), a four-channel timer (TMR) and dual watchdog timers. They also feature numerous serial data communication channels, six SCI, two SPI, and one I2C. Four channels of DMA and a Data Transfer Controller make it easy to handle transfers with peripherals and ensure efficient use of the CPU.
Many functional enhancements were made to reduce system costs and power consumption, including a Vbat pin for connection to a coin cell or super cap to automatically power the RTC and a tamper-detection system within the RTC to time stamp and store an intrusion event from three different, independent sources. The RX631 MCUs also feature an on-chip temperature sensor, on-chip 50 MHz oscillator to boot up a system at high speed and on-chip voltage reference for the A/D and D/A converters. Furthermore, thanks to an on-chip data flash with up to 100000 erase cycles and finer write/erase granularity at just 2-byte write and 32-byte erase, the need for an external EEPROM device is eliminated.
Developers are provided with a wide variety of hardware and software tools for design-in of the new MCUs. For example, the High-Performance Embedded Workshop (HEW) integrated development environment (IDE) from Renesas Electronics, which supports the low-cost E1 JTAG on-chip debugging tool as well as the comprehensive E20 high-speed trace on-chip debugging tool.
