Product details
Overview
R5F35L26JFE from Renesas Electronics is a 16-bit M16C/5L Group microcontroller featuring the M16C/60 Series CPU core, 128 KB program ROM 1, 16 KB RAM, 4 KB × 2 blocks data flash, and integrated CAN 2.0B module. It operates at up to 32 MHz with 3.0–5.5 V supply, supports -40°C to +85°C industrial temperature range, and is housed in an 80-pin LQFP (PLQP0080KB-A). It targets automotive control units and factory automation LAN systems requiring real-time communication and motor control.
For engineers reviewing the R5F35L26JFE datasheet, R5F35L26JFE pinout, R5F35L26JFE application, or R5F35L26JFE equivalent, key selection criteria include its single-chip 80-pin CAN-enabled MCU architecture, 27-channel 10-bit ADC, five 16-bit Timer A units with PWM and encoder support, three-phase motor control timer, and on-chip 40 MHz oscillator with PLL frequency synthesis.
Technical Context
The R5F35L26JFE implements the M16C/60 Series CPU core with 91 basic instructions, 16×16-bit multiplier, and 16×16+32-bit MAC unit, enabling deterministic 31.25 ns minimum instruction execution at 32 MHz. Its memory subsystem includes separate program ROM 1 (128 KB), program ROM 2, and dual-block data flash (4 KB × 2) with 10,000-program/erase endurance.
Peripherals are tightly coupled to the CPU via a DMAC supporting four cycle-steal channels and 41 trigger sources. The CAN module uses a dedicated 32-slot message buffer for mailbox-based arbitration and filtering, while Timer S provides eight input-capture/output-compare channels for precise waveform generation and time measurement.
