For engineers reviewing the R5F56104VDFP#H0 datasheet, R5F56104VDFP#H0 pinout, R5F56104VDFP#H0 application, or R5F56104VDFP#H0 equivalent, key selection criteria include wide-temp operation (−40°C to +85°C), 144-pin LQFP package compatibility, on-chip debug support via JTAG/SWD, and peripheral mix including TPU-based PWM generation and external bus interface for memory expansion.

Technical Context

The R5F56104VDFP#H0 implements the high-efficiency RX CPU core with one-instruction-per-clock execution, 32-bit multiplier/divider, and barrel shifter. Its memory subsystem includes 768 KB of on-chip flash with three programming modes (SCI boot, user program, user boot) and 32 KB data flash supporting EEPROM-like wear leveling.

Peripheral timing is decoupled across three clock domains: ICLK (8–100 MHz) for CPU/RAM/ROM, PCLK (8–50 MHz) for peripherals including A/D and D/A converters, and BCLK (8–25 MHz) for external bus operations. The interrupt controller supports 116 peripheral interrupts and 16 external IRQ pins with eight priority levels.

FAQ

What is the maximum operating frequency and voltage range for the R5F56104VDFP#H0?

The R5F56104VDFP#H0 operates at a maximum frequency of 100 MHz with a supply voltage range of 3.0 V to 3.6 V for VCC, PLLVCC, AVCC, and VREFH. The device is specified for −40°C to +85°C ambient operation, and all voltage rails must remain within tolerance across this temperature range to ensure reliable flash programming and analog converter accuracy.

Does the R5F56104VDFP#H0 support JTAG debugging and what pins are required?

Yes, the R5F56104VDFP#H0 supports full on-chip debugging via JTAG using pins P05 (TCK), P04 (TDI), P01 (TDO), P03 (TMS), and P02 (TRST#). These signals are assigned to dedicated LQFP pins 144, 1, 8, 2, and 6 respectively, and require no external level-shifting for standard 3.3 V debug probes compatible with ARM Cortex-M or Renesas E2/E2 Lite debuggers.

How many analog input channels does the R5F56104VDFP#H0 have and what is their resolution?

The R5F56104VDFP#H0 integrates four independent 10-bit A/D converter units, each with four input channels, for a total of 16 analog input channels (AN0–AN15). Each channel supports sample-and-hold, software or timer-triggered conversion, and operates with 1.0 µs conversion time when PCLK is set to 50 MHz - delivering consistent 10-bit linearity across the full −40°C to +85°C range.

What external memory interfaces are supported by the R5F56104VDFP#H0?

The R5F56104VDFP#H0 supports an 8-area external bus interface with independent chip-select signals (CS0#–CS7#), configurable data bus width (8- or 16-bit per area), and wait-state control. Each area supports up to 16 MB address space, and the BCLK domain runs up to 25 MHz - enabling direct connection to parallel NOR flash, SRAM, or FPGA peripherals without glue logic.

Is the R5F56104VDFP#H0 pin-compatible with other RX610 Group MCUs in the same package?

Yes, the R5F56104VDFP#H0 is fully pin-compatible with all other RX610 Group devices in the 144-pin LQFP package (PLQP0144KA-A), including R5F56106VDFP#H0, R5F56107VDFP#H0, and R5F56108VDFP#H0. Pin functions, power sequencing, and peripheral mappings are identical - allowing drop-in replacement when flash size or feature set requirements change.
