Oct 21, 2025

With the release of Cyclone software v11.66 and PROG v9.91, PEMicro’s development and production tools now support the Renesas RA4C1 MCU device family

The RA4C1 group are low power, 32-bit microcontrollers (MCUs) based on the Arm® Cortex®-M33 (CM33) core with TrustZone®, delivering an ideal balance of low voltage operation, low power consumption and high performance combined with an advanced security engine needed by many security sensitive applications. The RA4C1 offers up to 512 KB of code flash memory, 8 KB of data flash memory and 96 KB of SRAM 

The algorithms, Renesas_R7FA4C1BB_256KB.arp and Renesas_R7FA4C1BD_512KB.arp, include erase/program/verification support for the 256KB or 512KB code flash region respectively, the OSIS region, and the 8KB data flash region. 

New device support added for the following part numbers: R7FA4C1BB3CFP, R7FA4C1BB3CFM, R7FA4C1BD3CFP, R7FA4C1BD3CFM
