“The integrated USB peripherals of the M16C/6C, will open the M16C Platform to be used in a broad range of applications requiring connectivity as well as keeping the ease-of-use and compatibility to previous M16C products”, said Bernd Westhoff, Product Marketing of the Renesas Technology Europe CID BU, “We believe the M16C/6C will meet the customers expectation for a 16-bit general purpose microcontroller with USB 2.0 interface. With a high degree of integration this could help reduce system BOM to a minimum, e.g. due to single clock and voltage supply perspective.”
Other new features include a power-on reset (POR) function, a low-voltage detection (LVD) circuit, real-time clock (RTC), high-precision (40MHz) on-chip oscillator and a watchdog timer with an independent oscillator (125kHz). A hardware multi-master I2C-bus has also been added in place of the simplified I2C-bus.
In addition, on-chip peripheral functions have been improved to include a fast A/D converter, 6 USART, CRC unit and 4 DMA controllers. The 10-bit A/D converter achieves a fast conversion speed of 1.72 μs and offers 26 channels. The devices are available with on-chip Flash and RAM memory in density combinations of 128kB/12kB, 256kB/20kB, 384kB/31kB and 512kB/31kB. The ICs also have an extra flash memory for data storage. Two banks of 4kB DataFlash*2 each with an endurance of 10,000 cycles in both read and write operations, as well as a bank of 16kB to store a customised boot-loader are included.
Typical applications include EPOS barcode scanners, measurement equipment and a broad range of industrial equipment.
The new E8a on-chip debugging emulator is available as a development environment. The E8a can also be used as a flash programmer. A RSK starter-kit with supporting USB drivers is scheduled to be available shortly.
Currently being sampled, the M16C/6C group will be generally available soon.
