Renesas Electronics RX111 Group 32-bit MCUs

Renesas Electronics has announced additions to the RX111 Group 32-bit microcontrollers (MCUs), suitable for applications such as healthcare devices, industrial equipment and building automation systems. The company’s existing line-up offers package pin counts of 36 to 64 pins, flash memory capacity of 16 to 128 KB and RAM capacity of 8 to 16 KB.

Renesas has added 15 product versions with package pin counts of 48 or 64 pins and flash memory/RAM capacity of 256 KB/32 KB, 384 KB/64 KB or 512 KB/64 KB. At an operating frequency of 32 MHz, processing performance is 1.56 Dhrystone MIPS (DMIPS)/MHz and power consumption is 64 µA/DMIPS.

The standby voltage remains at 440 nA while retaining the contents of the on-chip RAM and register values. Returning to normal operating mode from software standby mode takes 4.8 µs. This means that during intermittent operation where switching between standby mode and normal operation occurs repeatedly, not only is the current consumption value reduced but current loss during wakeup from standby mode is reduced as well. Thus, it is possible to extend the operating duration of battery-powered products such as portable devices or healthcare devices.
