Renesas expands MCU portfolio, cuts system cost by 40%
1 min read
Two new MCU families have been introduced by Renesas. The RL78/G1G series is designed to cut system cost by 40%, while the RX111 group has been extended to offer memory capacities up to 512KB.
Designed to improve safety and efficiency, the RL78/G1G MCUs are aimed at small appliances and consumer products with expanded brushless DC motor control support.
Key features include an on chip PGA with software gain setting for amplifying very small signals; an on chip high speed comparator with response time 8x less than earlier products; and backward compatibility with earlier products, allowing reuse of existing software and shorter turnaround time.
The RX111 series of 32bit MCUs is aimed at healthcare devices, industrial equipment and building automation systems.
The devices come with a flash memory capacity of 512KB and RAM capacity up to 64KB, four times the maximum previously available.
Current consumption during operation is 64µA/DMIPS, and the standby voltage remains at 440nA while retaining the contents of the on chip RAM and register values.
The MCUs are available with different memory capacities to match different applications. They feature a high performance RXv1 CPU core with an operating frequency of 32MHz and processing performance of 1.56DMIPS/MHz.
