The R32/111 family

Renesas Technology Europe has announced the R32C/ 111 group of microcontrollers with on-chip flash memory and incorporating the R32C/ 100 high-performance 32-bit CPU core.

The group consists of 12 models and is suitable for a wide range of applications, including metering, industrial and consumer electronics. The R32C/100 series is the top-level product series in the M16C Platform (M16C Platform: a family of CISC microcontrollers, comprising a varied product lineup of 16-bit and 32-bit products in the M16C Series, M32C Series and R32C Series. Features include highly efficient C-language support, excellent noise characteristics, low power consumption, and comprehensive on-chip peripheral functions.) The range of low-end to highend series featuring the same architecture, pin assignment compatibility, and peripheral function upward-compatibility provides support for a wide range of application areas, including the automotive, industrial, and consumer fields) which is a CISC (Complex Instruction Set Computer) microcontroller. The core is upward compatible with existing CPU cores in the platform, and also provides improvements in operation processing performance, bus usage efficiency and code efficiency.

The R32C/111 group has a maximum operating frequency of 50MHz, which in combination with improvements to the CPU core architecture, enables an overall processing performance of 42 DMIPS executing code from embedded flash. It also incorporates an on-chip 32-bit multiplier, single-precision float-ing-point unit (FPU) and a 32-bit enhanced barrel shifter for dramatically improved operation processing performance. An expanded, on-chip 64-bit memory bus has improved bus efficiency.

The devices include a variety of on-chip peripheral functions, including a watchdog timer, high-functionality timers and four DMA controller channels. Additional features include nine free scalable USART, 26 channels of 10-bit A/D converter, two 8-bit D/A converter channels, a CRC cal-culation circuit for improved communication data reliability and an X-Y converter circuit supporting high-speed rotation or enlargement of image data. The R32C/111 uses the FlatRAM (FlatRAM: exclusive to Renesas Technology, FlatRAM means constant embedded RAM size, whatever embedded Flash size is chosen) approach. The basis of FlatRAM is that communication stacks, using the embedded RAM, do not shrink just because the flash demand goes down. The benefit of the FlatRAM approach is that engineers can use largest Flash product in their development phase and change later in mass production to the flash size most appropriate.

R32C/111 group products come in small 100-pin LQFP (14 × 14 mm) packages, which are the same packages used for the M16C/62P and M32C/87 products.

The R32C/111 is currently sampled to lead customers and samples will soon be generally available on demand. Sample quantity pricing for a 100-pin LQFP device is starting at €6.90.
