Renesas' new PMIC increases reliability and reduces design time

Renesas Electronics Corporation, a premier supplier of advanced semiconductor solutions, recently introduced the RAA215300 PMIC (power-management IC) optimized to complement Renesas’ RZ/V2L and RZ/G2L microprocessors (MPUs). It’s also designed for AI-enabled applications.

The new high-performance PMIC offers a wide range of features including nine channels, a built-in charger, and a real-time clock. The high integration of the new device reduces design complexity, speeding time-to-market for customers.

The RAA215300 includes six buck regulators, three LDOs, and a coin cell/supercap charger. It supports DDR4, DDR4L, DDR3, and DDR3L memory with dedicated VREF, VTT, and VPP rails. The new PMIC enables four-layer, printed-circuit boards that reduce costs. The high level of integration also increases system reliability due to fewer system components needed on the board.

The RAA215300 pairs with the RZ/G2L, RZ/V2L, and several other Renesas offerings in a winning combination for a scalable SMARC (smart mobility ARChitecture), SoM (system-on-module) with AI design.

In addition to the Renesas MPU and PMIC, this combination includes power controllers, a USB PD controller, and a clock device from Renesas. The company offers over 250 combinations that consist of complementary analog, power, timing devices, and embedded processing to provide an easy-to-use architecture.

They simplify the design process and significantly reduce design risk for customers in a wide variety of applications.

“Customers of our RZ/V2L and RZ/G2L MPUs will enjoy the performance advantages and ease-of-design of the RAA215300,” said Andrew Cowell, VP, Mobility, Infrastructure and IoT Power Business Division at Renesas. “In addition, its high integration and rich feature set makes it an excellent choice for consumer, industrial, and SoM applications.”
