FAQ
What is the maximum operating frequency of the R5F3640DDFB#30?
The R5F3640DDFB#30 operates at a maximum system clock frequency of 20 MHz. This is achieved either directly from an external crystal/resonator or via its on-chip PLL, which multiplies the input clock. At 20 MHz, the M16C core delivers up to 20 MIPS, with most instructions executing in a single cycle when accessing internal registers. The R5F3640DDFB#30 maintains full specification compliance across its entire industrial temperature range (−40°C to +85°C) at this frequency.
Does the R5F3640DDFB#30 support in-system programming (ISP)?
Yes, the R5F3640DDFB#30 supports in-system programming via its on-chip bootloader, accessible through UART0. The bootloader enables field firmware updates without requiring external programming hardware. It verifies Flash write integrity using checksums and supports protected memory regions to prevent accidental overwrites of critical boot code. This capability is fully documented in the R5F3640DDFB#30 Hardware Manual (REJ03B0216) and requires no external circuitry beyond standard UART level-shifting.
What are the power supply requirements for the R5F3640DDFB#30?
The R5F3640DDFB#30 requires a single 2.7 V to 5.5 V supply on VCC, with corresponding VSS return. It does not require separate analog or I/O supplies - all internal circuits (core, Flash, ADC, timers, and I/O) operate from this rail. Decoupling mandates at least one 100 nF ceramic capacitor per VCC–VSS pair, placed within 5 mm of each power pin. The R5F3640DDFB#30 draws 12 mA typical at 20 MHz/5 V and drops to <1 µA in Deep Stop mode, enabling battery-operated deployments.
Is the R5F3640DDFB#30 pin-compatible with other M16C/64 Group devices?
The R5F3640DDFB#30 is pin-compatible with other 100-pin LQFP variants in the M16C/64 Group, including R5F3641DDFB#30 and R5F3650DDFB#30. All share identical pin assignments, electrical characteristics, and mechanical footprint. However, differences in on-chip peripheral count (e.g., CAN presence in R5F3650DDFB#30) and memory size mean software is not automatically portable - register-level initialization must account for enabled/disabled modules. The R5F3640DDFB#30 datasheet confirms full pin compatibility within this LQFP subgroup.
What debug interface does the R5F3640DDFB#30 provide?
The R5F3640DDFB#30 integrates a single-pin Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, enabling full JTAG-equivalent functionality - including halt/resume, register read/write, Flash programming, and real-time variable monitoring - using only SWDIO and shared VCC/GND. No external debug probe is required beyond a standard SWD adapter. This interface remains active in all low-power modes except Deep Stop, and is fully supported by Renesas' E2 studio IDE and CS+ development tools for the R5F3640DDFB#30.
