FAQ
What is the maximum operating frequency of the R5F61655D50FPV?
The R5F61655D50FPV supports a maximum CPU clock frequency of 40 MHz, achieved using the on-chip PLL with programmable multiplication (×1 to ×4) from internal or external clock sources. This frequency is fully supported across the full −40 °C to +85 °C operating temperature range and 3.0–3.6 V supply voltage, as verified in the H8SX/1655 Group Hardware Manual Rev.2.00.
Does the R5F61655D50FPV include a CAN controller?
No, the R5F61655D50FPV does not integrate a CAN controller. Its serial communication peripherals consist of two SCI modules supporting UART/RS-232/RS-485 protocols only. CAN functionality requires external transceiver and software-based protocol stack implementation. This aligns with the H8SX/1655 Group's focus on non-automotive industrial control where CAN is not mandatory.
What is the Flash memory endurance and data retention specification for the R5F61655D50FPV?
The R5F61655D50FPV specifies 10,000 write/erase cycles for its 512 KB on-chip Flash memory and guarantees data retention of 20 years at +85 °C or 100 years at +25 °C. These values are documented in the H8SX/1655 Group Hardware Manual Rev.2.00 and apply to standard block erase (1 KB) and word programming operations under rated voltage and temperature conditions.
Can the R5F61655D50FPV operate from a 3.3 V supply without level shifters?
Yes, the R5F61655D50FPV is fully specified for 3.0–3.6 V operation, making it directly compatible with standard 3.3 V logic families. All I/O pins are 3.3 V tolerant with VIH(min) = 2.0 V and VIL(max) = 0.8 V, and the internal regulators support clean core voltage derivation - eliminating need for external level shifters in typical 3.3 V system designs.
Is the R5F61655D50FPV pin-compatible with other devices in the H8SX/1655 Group?
Yes, the R5F61655D50FPV shares identical pin assignment and electrical characteristics with other 100-pin LQFP variants in the H8SX/1655 Group, including R5F61655D50FP, R5F61652D50FPV, and R5F61652D50FP. This allows hardware reuse across firmware variants while maintaining mechanical and signal-integrity compatibility per the H8SX/1655 Group Hardware Manual Rev.2.00 pinout definition.
