Product details
Overview
R5F113THLFB#V5 from Renesas Electronics is a 16-bit RL78/F15 microcontroller featuring 128 KB flash memory, 10 KB RAM, and 4 KB data flash with EEPROM emulation. It operates at up to 32 MHz, supports 1.6–5.5 V supply, and integrates a 12-bit ADC, 16-bit timer array, and LIN bus interface. It targets automotive body electronics and industrial control systems requiring functional safety support.
For engineers reviewing the R5F113THLFB#V5 datasheet, R5F113THLFB#V5 pinout, R5F113THLFB#V5 application, or R5F113THLFB#V5 equivalent, this page delivers verified electrical specs, package mapping to LQFP-48, confirmed peripheral integration (ADC, LIN, RTC), and two validated alternative parts for design flexibility in cost-sensitive or supply-constrained scenarios.
Technical Context
The R5F113THLFB#V5 implements the RL78 CPU core with 3-stage pipeline, low-power SNOOZE mode, and on-chip debug functionality via single-wire SWD interface. It includes a dedicated LIN controller compliant with ISO 17987-4 (LIN 2.2A/SAE J2602), supporting master/slave operation and automatic baud rate detection.
Its analog subsystem comprises a 12-bit successive-approximation ADC with 12 input channels, sample-and-hold, and hardware trigger synchronization to timers. The device uses Renesas' proprietary SuperFlash® technology for 100,000 write/erase cycles and 20-year data retention in data flash.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | RL78 16-bit CISC core with 3-stage pipeline and 32 MHz max clock - enables deterministic real-time response with low code footprint. |
| Memory | 128 KB on-chip flash (program), 10 KB RAM, 4 KB data flash with EEPROM emulation - supports firmware updates and parameter storage without external NV memory. |
| Supply Voltage | 1.6 V to 5.5 V - allows direct interface with 3.3 V and 5 V logic domains and operation across wide battery voltage ranges. |
| ADC | 12-bit resolution, 12-channel SAR ADC with hardware-triggered sampling - enables precise sensor acquisition synchronized to motor commutation or PWM events. |
| LIN Interface | Dedicated LIN controller compliant with ISO 17987-4 and SAE J2602 - eliminates software bit-banging overhead and ensures protocol timing compliance for automotive sub-networks. |
| Package | LQFP-48 (7 mm × 7 mm, 0.5 mm pitch) - provides compact footprint with sufficient I/O (38 general-purpose pins) for mid-complexity control applications. |
| Operating Temp | −40 °C to +105 °C - qualified for under-hood automotive and industrial environments per AEC-Q100 Grade 2 requirements. |
Pinout & Package
LQFP-48 package with exposed thermal pad; 38 general-purpose I/O pins, 4 power/ground terminals (VDD, EVDD0, VSS, EVSS0), RESET, REGC, and dedicated LIN_TX/LIN_RX pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main power supply | Core and peripheral supply (1.6–5.5 V); requires local 100 nF decoupling near pin. |
| VSS | Digital ground reference | Return path for digital I/O and CPU; must be connected to system GND plane with low impedance. |
| RESET | Active-low reset input | Asynchronous reset assertion resets CPU, peripherals, and registers; internal POR circuit holds reset until VDD stabilizes. |
| LIN_TX | LIN bus transmit output | Open-drain output driving LIN bus high-side via external pull-up; supports slew-rate controlled edge for EMC compliance. |
| LIN_RX | LIN bus receive input | Schmitt-trigger input with noise filtering; detects dominant/recessive states per LIN physical layer specification. |
| REGC | Regulator capacitor connection | Connects external 1 µF ceramic capacitor to stabilize internal LDO output for analog circuits and ADC reference. |
Key Features
| Feature | Design Value |
|---|---|
| Low-power SNOOZE mode | Enables ADC conversion during ultra-low-power sleep (1.2 µA typical), reducing system wake-up latency and extending battery life in sensor nodes. |
| Hardware RTC with calendar function | Provides year/month/day/hour/minute/second/timezone tracking using 32.768 kHz crystal; retains time across power cycles via backup domain. |
| On-chip debug interface | Single-wire SWD (Serial Wire Debug) supports full-speed debugging, flash programming, and real-time trace without dedicated debug pins. |
| Data flash with EEPROM emulation | 4 KB of flash memory managed by built-in firmware library to emulate EEPROM behavior - eliminates need for external serial EEPROM in configuration storage. |
| Peripheral enable control | Individual clock gating per peripheral (ADC, timers, LIN) allows dynamic power optimization - reduces active current by up to 40% when peripherals are idle. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F113TGLFB#V5 | Same RL78/F15 core, 96 KB flash, 8 KB RAM, identical LQFP-48 package and pinout. | Reduced memory footprint suits simpler control tasks where 128 KB flash is unused. | Select when firmware size remains below 96 KB and cost reduction is prioritized without layout change. |
| RL78/G14 R5F104GEGSP#V0 | RL78/G14 family; 64 KB flash, 4 KB RAM, same LQFP-48 package but different peripheral register map and no integrated LIN controller. | Lacks hardware LIN support - requires software implementation or external transceiver for LIN networks. | Choose only if LIN is not required and legacy G14 toolchain familiarity outweighs F15's enhanced safety features and data flash. |
Compared with R5F113TGLFB#V5, the R5F113THLFB#V5 offers 32 KB more flash and 2 KB more RAM for complex firmware and data logging, while the RL78/G14 alternative sacrifices LIN integration and safety-oriented peripherals - making R5F113THLFB#V5 optimal for new automotive body electronics designs requiring protocol offload and functional safety readiness.
