I. Renesas MCU product series prioritised by Mingjiada
1. RA Series – High-performance Arm Cortex-M microcontrollers
The RA Series is a family of high-performance MCUs from Renesas utilising Arm Cortex-M cores, widely used in industrial automation, IoT devices, consumer electronics and healthcare sectors.
RA8 Series (Flagship): Based on a 1GHz Arm Cortex-M85 core, featuring Helium vector acceleration technology and TrustZone security functions, it is suitable for high-computational-power scenarios such as edge AI inference, graphical human-machine interfaces and industrial Ethernet. The RA8P1 integrates the Ethos-U55 NPU, delivering 256 GOPS of AI inference performance, making it ideal for edge intelligence applications such as facial recognition, object detection and speech recognition. The RA8D2 specialises in high-definition graphical HMIs and vision AI, supporting 1280×800 LCD displays and MIPI-DSI interfaces.
RA6 Series: Featuring a Cortex-M4 core and an integrated Ethernet MAC, this series is suitable for wired Ethernet applications, industrial robots, HVAC control and metering devices.
RA4 Series: The RA4C1 features ultra-low power consumption, with an active power consumption of just 168 µA/MHz and a standby current as low as 1.79 µA; it is specifically designed for battery-powered applications such as smart electricity meters, gas meters, water meters and smart locks.
RA2 Series: Entry-level Cortex-M23 core, supporting a wide voltage range of 1.6 V to 5.5 V, suitable for battery-powered devices, wearables, PC peripherals and home appliance control, amongst others.
2. RX Series – High-Performance 32-bit Microcontrollers
The RX Series is Renesas’ classic 32-bit MCU product line, renowned for its outstanding real-time performance and motor control capabilities; it is widely used in industrial automation, home appliance motor control and the Internet of Things (IoT).
RX13T Series: Specifically designed for single-motor variable-frequency control, it integrates the MTU3 multi-function timer, a 12-bit A/D converter and a programmable gain amplifier. It is widely used in air-conditioning fans, washing machine motors, IH induction hobs, fridge compressors, drainage pumps and power tools.
RX23W Series: An RF MCU with integrated Bluetooth 5.0, suitable for wireless IoT applications such as wearable health monitoring devices, smart home systems and industrial sensor networks.
RX100/RX200/RX600/RX700 Series: Covering a full range of requirements from entry-level to flagship models, these are suitable for industrial robots, PLCs, variable-frequency drives, smart door locks and electric bicycles, amongst others.
3. RL78 Series – Ultra-low-power 16-bit microcontrollers
The RL78 series is renowned for its industry-leading low-power characteristics (just 37.5 µA/MHz during normal operation) and is the ideal choice for battery-powered devices, portable medical equipment, industrial sensing and smart home applications.
RL78/G13 Series: Standard, general-purpose core models with Flash memory ranging from 16KB to 512KB, suitable for small household appliances, industrial data acquisition and portable devices.
RL78/F Series: 16-bit MCU evaluation kits designed for automotive electronics applications.
4. RH850 Series – Automotive-grade 32-bit microcontrollers
The RH850 series is Renesas’ flagship product line for automotive electronics, with cumulative shipments exceeding 4 billion units since 2013.
RH850/U2C: Manufactured using a 28 nm process and supporting the ASIL D functional safety level, it is widely used in body control applications such as chassis and safety systems, battery management systems (BMS), lighting and motor control.
RH850/U2A/U2B: Cross-domain MCUs, suitable for domain controllers, ADAS and smart cockpits.
RH850/C1M-Ax: Designed specifically for hybrid and electric vehicles (HEV/EV), supporting starter/generator systems and traction inverter applications.
RH850/P1x: Aimed at chassis applications such as electric power steering (EPS) and braking systems.
