Product details
Overview
R5F2134AGKFP#W4Q from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/34G Group, featuring a 20 MHz max operating frequency, 96 KB flash program memory, 8 KB RAM, and 10-bit × 12-channel ADC with sample-and-hold. It integrates UART0/1/2 (with I²C and IE BUS modes), SSU, hardware LIN, and operates across –40°C to +125°C for automotive body control applications.
For engineers reviewing the R5F2134AGKFP#W4Q datasheet, R5F2134AGKFP#W4Q pinout, R5F2134AGKFP#W4Q application, or R5F2134AGKFP#W4Q equivalent, key selection criteria include its K-grade temperature rating, absence of CAN module (R8C/34G Group), presence of data flash with BGO, and 48-pin LQFP package compatibility with industrial and automotive ECU designs.
Technical Context
The R5F2134AGKFP#W4Q implements the R8C/Tiny CPU core with 89 fundamental instructions and 50 ns minimum instruction execution time at 20 MHz. It supports single-chip mode with 1 Mbyte address space, includes a 16×16→32-bit multiplier and MAC unit, and uses three clock sources: XIN oscillator, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator.
It features six timer modules (RA–RE and dual RD), DTC with 31 activation sources, voltage detection circuit with power-on reset and selectable VDET1 level, and 43 CMOS I/O ports with configurable pull-up resistors. The device lacks CAN but retains hardware LIN (using Timer RA and UART0) and supports I²C-bus via UART2.

Use Value: Dual 16-bit Timer RD supports complementary PWM for bidirectional motor control with dead-time insertion; BGO allows seat profile updates mid-operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21348GKFP | 64 KB program ROM, 6 KB RAM, same R8C/34G feature set and K-temp rating | Suitable where reduced code size suffices and cost optimization is prioritized | Select when firmware footprint fits within 64 KB and data flash usage remains ≤4 KB |
| R5F2134AGJFP | Identical functionality but J-version (–40°C to +85°C) and PLQP0048KB-A package | Targeted at cabin-mounted modules or non-under-hood automotive subsystems | Choose for lower-cost thermal qualification where ambient temperature stays below 85°C |
Compared with R5F2134AGKFP#W4Q, R5F21348GKFP offers smaller memory and lower cost for simpler nodes, while R5F2134AGJFP provides identical peripherals with relaxed temperature grading-both require no PCB redesign but differ in thermal margin and memory headroom for future firmware expansion.

FAQ
Does R5F2134AGKFP#W4Q include a CAN controller?
No, R5F2134AGKFP#W4Q belongs to the R8C/34G Group, which explicitly excludes the CAN module. This distinguishes it from R8C/34E/F Group variants (suffix E/F) and aligns with applications where LIN suffices-such as door modules or seat controls. The R5F2134AGKFP#W4Q datasheet confirms absence of CAN registers, mailboxes, and related peripheral circuitry.
What is the purpose of the "#W4Q" suffix in R5F2134AGKFP#W4Q?
The "#W4Q" suffix denotes a specific tape-and-reel packaging and marking variant per Renesas' ordering convention: W4 indicates embossed carrier tape (8 mm width, 4 mm pocket depth), and Q signifies RoHS-compliant, lead-free finish. This does not affect electrical or functional specifications of R5F2134AGKFP#W4Q-it remains fully compatible with standard PLQP0048KB-A footprint and K-grade operation.
Can R5F2134AGKFP#W4Q execute code from data flash while writing to it?
No, R5F2134AGKFP#W4Q supports Background Operation (BGO) only for data flash erasure and programming-not for concurrent code execution from that same memory block. Code must run from program ROM or RAM during data flash writes. BGO allows the CPU to continue processing while data flash operations complete, but execution from data flash is prohibited per R8C/34G architecture.
How many PWM output pins does R5F2134AGKFP#W4Q support?
R5F2134AGKFP#W4Q supports up to 6 dedicated PWM output pins via Timer RD's reset synchronous and complementary PWM modes-enabling three-phase motor control. Additional PWM-capable pins are available on Timer RB (1 pin), Timer RC (3 pins), and Timer RD's PWM3 mode (2 pins), but simultaneous use depends on pin multiplexing and mode configuration per the R5F2134AGKFP#W4Q pin assignment table.
Is R5F2134AGKFP#W4Q qualified for automotive AEC-Q100 stress testing?
R5F2134AGKFP#W4Q is specified for –40°C to +125°C operation (K version) and targets automotive body electronics, but Renesas does not list explicit AEC-Q100 qualification status for this part in publicly available documentation. Its R8C/34G Group positioning and K-temp grade indicate design intent for automotive environments; however, formal AEC-Q100 certification must be confirmed directly with Renesas or authorized distributors before deployment in safety-critical vehicle systems.
