What is the maximum operating frequency of the R7F7010343AFP#AA3?
The R7F7010343AFP#AA3 operates at a maximum CPU frequency of 240 MHz, achieved via its integrated PLL using an external 4–20 MHz crystal or clock source on the CLKIN pin. This frequency applies to both lockstep cores simultaneously, with cycle-accurate synchronization maintained across all instructions. The R7F7010343AFP#AA3 sustains this frequency across its full −40°C to +125°C operating range when supplied with VDD_1P2 = 1.2 V ±3% and proper thermal management.
