Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F35L26DFE | Same M16C/5LD Group, 128 KB program ROM 1, 12 KB data flash, identical 80-pin LQFP package and peripheral set | Lower memory capacity suits cost-sensitive designs with smaller firmware footprints | Select when application firmware fits within 128 KB and data logging requirements are ≤12 KB |

FAQ
What is the maximum operating frequency and voltage range for the R5F35L2EDFE?
The R5F35L2EDFE operates up to 32 MHz at a supply voltage of 3.0 V to 5.5 V, achieving a minimum instruction execution time of 31.25 ns. At 25 MHz, it supports a wider voltage range of 2.7 V to 5.5 V - enabling flexible power architecture design in mixed-voltage systems while maintaining full peripheral functionality across both modes.
Does the R5F35L2EDFE include an integrated CAN controller, and what version does it support?
Yes, the R5F35L2EDFE includes a single-channel CAN module compliant with CAN 2.0B specification, featuring a 32-slot message buffer for efficient mailbox-based transmission and reception. This integrated CAN interface eliminates the need for external transceivers beyond the physical layer, simplifying design for factory automation LAN and distributed control systems.
How many analog-to-digital converter channels does the R5F35L2EDFE provide, and what is their resolution?
The R5F35L2EDFE provides two independent A/D converter blocks: a 27-channel 10-bit A/D circuit and a separate 4-channel 10-bit A/D1 circuit. Both support simultaneous sampling control and feature dedicated AVCC, AVSS, and VREF pins - delivering consistent 10-bit precision for sensor monitoring, power supply supervision, and motor current feedback in industrial applications.
What low-power modes are supported by the R5F35L2EDFE, and how are wake-up sources configured?
The R5F35L2EDFE supports Wait mode and Stop mode, both accessible via software control. Wake-up is enabled from multiple sources including external interrupts (INT0–INT5, NMI), key input pins (KI0–KI3), real-time clock alarm, CAN message reception, and timer events. Each source is individually maskable in the interrupt controller, allowing granular power optimization in battery-backed or energy-conscious designs.
Is the R5F35L2EDFE pin-compatible with other members of the M16C/5LD Group, and what package does it use?
Yes, the R5F35L2EDFE uses the PLQP0080KB-A (80P6Q-A) 80-pin LQFP package and shares identical pinout with all other 80-pin M16C/5LD Group MCUs, including R5F35L23DFE and R5F35L26DFE. This allows direct substitution within the same package family for memory-scaling or qualification-driven revisions without PCB layout changes.
