Small RX651 32-bit MCUs for IoT connectivity modules
The new additions to Renesas’ RX651 MCU Group feature a 64-pin (4.5mm x 4.5mm) BGA package that has a 59 percent smaller footprint than the 100-pin LGA, and a 64-pin (10mm x 10mm) LQFP that is 49 percent smaller than the 100-pin LQFP.
The new MCUs feature connectivity, Trusted Secure IP (TSIP), and trusted flash area protection. The new RX651 devices support OTA reprogramming with integrated TSIP, enhanced flash protection, and other advancements.
The 64-pin MCUs are based on the high-performance RXv2 core and built on a 40nm process that provides a 520 CoreMark score at 120 MHz, and a 35 CoreMark/mA score according to EEMBC Benchmarks.
Integrated dual bank flash memory allows high root-of-trust levels through the combination of TSIP tp protect the encryption key; encryption hardware accelerators, such as AES, 3DES, RSA, SHA, and TRNG; and code flash area protection. The dual bank flash function supports BGO (Back Ground Operation) and SWAP.
