  • Release on:2024-04-12

On April 9, 2024, Beijing News -Global Semiconductor Solutions Supplier Ruisa Electronics (TSE: 6723) today announced the launch of the ARM? Cortex? -M23 processor RA0 microcontroller (MCU) series.The new 32 -bit general -purpose MCU RA0 series products also provide ultra -low power consumption performance in addition to lower costs.

The current consumption of RA0 products is only 84.3 μA/MHz, and the sleep mode is only 0.82mA.In addition, Ruisa also provides software standby mode in this new MCU, which can further reduce power consumption by 99%to a minimal value of 0.2 μA.In conjunction with the quickly wake up the HOCO (HOCO), this ultra -low -power MCU consumer electronics equipment, small appliances, industrial system control and building automation applications for battery have brought ideal solutions.

Function set for low -cost optimization
Risa has now launched the first product group of the RA0 series: RA0E1.The function set of this product is optimized for cost -sensitive applications, supporting a wide working voltage range of 1.6V to 5.5V. Customers do not need to use the level converter/regulator in the 5V system.The RA0 MCU also integrates timers, serial communication, and simulation functions, security functions and human -machine interface (HMI) functions to reduce customer BOM costs.In addition, this series of products also offers a variety of packaging options, including 3mm x 3mm miniature 16 pins QFN packaging.

The high -precision (± 1.0%) of the new MCU (± 1.0%) of the oscillator (HOCO) has improved the Potter rate accuracy, and the designer can save the independent oscillator.In addition, unlike other HOCOs, this accuracy can still be maintained in an environment from -40 ° C to 105 ° C. Such a broad temperature range allows customers to perform expensive and time-consuming " Filter ".

RA0E1 MCU not only has key diagnostic security functions and IEC60730 self -inspection library, but also provides rich guarantee functions for data security, such as real random number generators (TRNG) and AES libraries, which are suitable for IoT applications including encryption.

Akihiro Kuroda, Vice President of the Embedded Processing 2nd Division At Renesas said: "As a leader in the field of embedded processing, our customers hope that Risa can create the best solutions for various applications. The RA0E1 MCU product group can provide prices for prices. The ultra -low power consumption and low cost required for sensitive systems, while maintaining functional security, data security and design convenience. Combined with the high -performance RA8 series we recently launched, Risa can now be a variety of customers in all regions of the world. Application brings a first -class MCU solution. "

Paul Williamson, Senior Vice President and General Manager, IOT LINE of Business at ARM said: "Low -power IoT embedded applications in market automation and smart home furnishings have clear requirements for performance, efficiency, and data security. The RA MCU product family built by Sakki in ARM technology currently provides various solutions from low -power RA0 MCU to high -performance AI function RA8 products. And all products use the general design environment, which can achieve relaxed and rapid development and migration. ","

The key features of the RA0E1 MCU product group
Core: 32MHz ARM Cortex-M23
Storage: Integrated code flash memory of 64KB and 12KB SRAM
Exterior exterior: 12 -bit ADC, temperature sensor, internal reference voltage
Communication peripherals: 3 UART, 1 Different step UART, 3 Simplified SPI, 1 IIC, 3 Simplified IIC
Functional security: SRAM's puppet verification, invalid memory access detection, frequency detection, A/D test, unsusable storage, CRC calculator, register writing protection
