The R5F56609BGFL#10 operates at a maximum system clock frequency of 120 MHz. Its 1-Mbyte on-chip code flash supports zero-wait-state access at this speed, enabling deterministic real-time execution without pipeline stalls. This capability is confirmed in Renesas datasheet R01DS0393EJ0100 Rev.1.00, Section 1.1 and Table 1.1. The R5F56609BGFL#10 achieves 709 CoreMark at 120 MHz, validating sustained throughput.

Does the R5F56609BGFL#10 include a hardware floating-point unit (FPU)?

Yes, the R5F56609BGFL#10 integrates a single-precision IEEE 754-compliant hardware FPU as part of the RXv3 CPU core. It supports 32-bit floating-point arithmetic including addition, multiplication, division, and square root, accelerating motor control algorithms, sensor fusion, and digital filter computations. This is documented in Section 1.1 (Table 1.1) and Section 2.2 of the R01DS0393EJ0100 datasheet. The R5F56609BGFL#10 uses the FPU to achieve deterministic execution in time-critical loops.

What is the package type and thermal rating of the R5F56609BGFL#10?

The R5F56609BGFL#10 is housed in a 144-pin Low-profile Quad Flat Package (LFQFP) designated PLQP0144KA-B: 20 × 20 mm body, 0.5 mm pitch, with exposed thermal pad. It is rated for the G-version industrial temperature range of –40°C to +105°C, verified per Renesas specification R01DS0393EJ0100 Rev.1.00, Table 1.1 and Package Outline Drawing. This makes the R5F56609BGFL#10 suitable for under-hood, drive cabinet, and outdoor metering environments.
