Product details
Overview
R5F35L2EKFE#U0 from Renesas is an 80-pin LQFP M16C/5LD Group 16-bit microcontroller with M16C/60 Series CPU core, 256 KB program ROM 1, 16 KB RAM, 20 KB data flash, integrated CAN module (32-slot message buffer), and operating range of −40°C to +85°C. It delivers 32 MHz max operation at 3.0–5.5 V supply and supports factory automation LAN systems requiring real-time control, motor timing, and multi-protocol serial communication.
For engineers reviewing the R5F35L2EKFE#U0 datasheet, R5F35L2EKFE#U0 pinout, R5F35L2EKFE#U0 application, or R5F35L2EKFE#U0 equivalent, this page provides verified technical context, package mapping, functional pin roles, CAN-enabled industrial control use cases, and two confirmed alternative parts for design continuity planning.
Technical Context
The R5F35L2EKFE#U0 implements a single-chip M16C/60 Series CPU core with 16×16-bit multiplier and multiply-accumulate unit, executing instructions in as little as 31.25 ns at 32 MHz. Its memory architecture includes three distinct flash regions-program ROM 1 (256 KB), program ROM 2 (16 KB), and data flash (20 KB)-with 10,000-cycle endurance for data flash writes.
It integrates five 16-bit Timer A units supporting PWM, event counting with two-phase encoder input (×3), and programmable output mode (×3); three 16-bit Timer B units for pulse-width/frequency measurement; one dedicated three-phase motor control timer using TA1/TA2/TA4/B2; and a CAN 2.0B-compliant module with 32-slot message buffer and CTX0/CRX0 physical interface pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F35L2EDFE | Same 80-pin LQFP package, identical CPU/peripherals, but 256 KB program ROM 1, 16 KB RAM, 20 KB data flash - matches R5F35L2EKFE#U0 memory configuration exactly. | No functional difference; pin-compatible replacement with identical marking format (FE suffix = 80-pin). | Select when sourcing requires same memory map and package without revision-level constraints. |
| R5F3562EDFE | M16C/56D Group variant: identical package, CPU, RAM, and flash sizes, but lacks CAN module and CTX0/CRX0 pins. | Suitable only where CAN is not required; cannot substitute in factory automation LAN nodes. | Choose for cost-sensitive motor control or HMI applications where CAN is unused and BOM simplification is prioritized. |
