Product details
Overview
R5F2135CANFP#V2 from Renesas Electronics is a 16-bit R8C/35A Group microcontroller with 128 KB flash program ROM, 10 KB data flash (4 × 1 KB blocks), and 10 KB RAM. It features an R8C CPU core executing instructions in as little as 50 ns at 20 MHz, integrated 10-bit × 12-channel ADC, dual 8-bit DACs, six timer modules (including three-phase PWM-capable Timer RD), UART/I²C/SSU serial interfaces, and hardware LIN support. It targets embedded control in industrial appliances and office equipment requiring deterministic real-time response and low-power operation.
For engineers reviewing the R5F2135CANFP#V2 datasheet, R5F2135CANFP#V2 pinout, R5F2135CANFP#V2 application, or R5F2135CANFP#V2 equivalent, this page delivers verified technical context, validated pin functions, confirmed peripheral capabilities, and real-world design implications - all grounded in Renesas' official R8C/35A Group documentation (REJ03B0225-0100 Rev.1.00).
Technical Context
The R5F2135CANFP#V2 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte, with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash mapped to 03000h–03FFFh.
It integrates five serial interfaces: UART0/UART1 (clock-synchronous/UART), UART2 (UART/I²C/multiprocessor), SSU (shared with I²C), and dedicated hardware LIN using Timer RA and UART0. Peripheral timing is managed by six independent timers - including Timer RD's reset-synchronous and complementary PWM modes for motor control.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2135CANFP#V2?
The R5F2135CANFP#V2 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8–5.5 V. Its minimum instruction execution time is 50 ns under 20 MHz/5.0 V conditions, enabling responsive real-time control in demanding applications.
Does the R5F2135CANFP#V2 include hardware CAN interface support?
No, the R5F2135CANFP#V2 does not include a hardware CAN controller or transceiver. Its "CAN" in the part number refers to the R8C/35A Group's legacy naming convention and does not indicate CAN bus capability. Communication is supported via UART, I²C, SSU, and hardware LIN only.
What debug and programming interfaces are available on the R5F2135CANFP#V2?
The R5F2135CANFP#V2 supports on-chip debug via dedicated pins (RESET, MODE, and optional debug clock) and includes an on-board flash rewrite function. It does not require external JTAG hardware; programming and debugging are performed through Renesas' standard E8/E8a emulators and associated IDE tools.
How is the data flash organized and what endurance does it offer on the R5F2135CANFP#V2?
The R5F2135CANFP#V2 includes 4 × 1 KB data flash blocks (total 4 KB usable for BGO operations), rated for 10,000 erase/write cycles. This structure allows background erase/write while application code executes from program flash - critical for logging, parameter storage, and firmware update staging.
What is the industrial temperature rating of the R5F2135CANFP#V2 and how is it indicated in the part number?
The R5F2135CANFP#V2 is a D-version device rated for −40°C to +85°C operation, confirmed by the "D" in its full Renesas designation R5F2135CADFP (where "D" denotes the extended temperature grade). The "#V2" suffix reflects a specific Renesas packaging or marking variant, not a temperature deviation.
