Renesas Electronics announced the introduction of the new RL78 family of low-power microcontrollers (MCUs). The RL78 integrates advanced features from both the R8C and the 78K (78K0, 78K0R) families to deliver lower power, enhanced performance and higher integration, providing a migration path. The new products are built around the new RL78 CPU core, which is based on the 78K0R CPU core and incorporates an extensive range of powerful peripheral functions from the R8C and 78K families, making them ideal for a number of applications including battery-operated devices and household applications.
The new MCUs boast operating current of only 70 μA/MHz and standby current of 0,7 μA with the real-time clock (RTC) and low-voltage detection (LVD) functions active. The new family’s power-efficient design, based on a 130 nm process node, can deliver 41 Dhrystone million instructions per second (DMIPS) when operating at 32 MHz. The devices integrate a 32 MHz ±1% on-chip oscillator, data Flash with background operation supporting up to 1 million re-write cycles and 1,6 to 5,5 V operation.
The RL78 family is comprised of both general-purpose and application-specific standard MCUs. The general-purpose ‘G’ series will include a total of 302 products in the RL78/G12 group and RL78/G13 group. The initial products will offer extensive scalability with 2 KB to 512 KB of program space and with package options ranging from 20 to 128 pins.
