FAQ

What is the maximum operating frequency of the R5F572NDDGBG#20?

The R5F572NDDGBG#20 operates at a maximum frequency of 240 MHz using its on-chip PLL with external crystal or clock input. This frequency is fully supported across the full industrial temperature range (–40°C to +105°C) and enables 428.6 CoreMark/MHz performance. The R5F572NDDGBG#20 maintains timing compliance under worst-case voltage (2.7 V) and temperature conditions per Renesas datasheet R01DS0343EJ.

Does the R5F572NDDGBG#20 include hardware cryptographic acceleration?

Yes, the R5F572NDDGBG#20 integrates dedicated hardware accelerators for AES-128/256 (ECB/CBC/CTR/GCM), SHA-1/224/256, TRNG, and RSA/ECC (up to 4096-bit). These units operate independently of the CPU core, reducing TLS 1.3 handshake latency to under 12 ms. The R5F572NDDGBG#20 uses these accelerators to enable secure boot, encrypted firmware updates, and authenticated cloud telemetry without compromising real-time task scheduling.
