R5F10DPGJFB - RL78/D1A 16-bit MCU, 128KB Flash, 100-pin LFQFP | Renesas
MPN: R5F10DPGJFB ✗ Tapus ng BuhayR5F10DPGJFB Ulas
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The RL78 is Renesas's 16-bit CISC core family engineered for ultra-low-power embedded applications, positioned below the RX family in the Renesas 16/32-bit MCU hierarchy. Automotive-grade RL78 derivatives extend the platform into AEC-Q100-qualified instrument cluster, body control, and HVAC segments where low quiescent current and integrated analog front-ends reduce external BOM.
Key features of the R5F10DPGJFB include an integrated sound generator (100 Hz to 6 kHz tone range), automatic volume decrement for turn-signal click feedback, four stepper motor controller/driver channels for analog gauge pointers, an LCD controller/driver supporting automotive cluster displays, and automotive-qualified temperature range operation. The 100-pin LFQFP package exposes generous GPIO and analog channels for sensor interfacing typical of instrument clusters.
The RL78/D1A architecture combines a CISC 16-bit core with on-chip debug, low-voltage detection, watchdog timer, and multiple serial interfaces (CSI/UART/I2C). The integrated sound generator uses PWM-driven tone synthesis, and the stepper motor drivers include 8-bit microstepping resolution for smooth pointer movement. Together these blocks reduce the discrete component count of a typical cluster board significantly.
Typical applications include automotive low-end instrument clusters (speedometer, tachometer, fuel and temperature gauges), HVAC control panels with LCD readouts, automotive body controllers requiring stepper-driven actuators, and turn-signal click generators that reuse the on-chip tone block. The device is particularly suited to entry-level clusters where cost-effective integration replaces multiple external ICs.
Designers should plan PCB layout for thermal relief on the LFQFP exposed pad and follow Renesas application notes for stepper motor current tuning. Note that the R5F10DPGJFB has been replaced by Renesas with the R5F10DPGCJFB#56; new designs should evaluate this successor unless pin/feature compatibility with legacy firmware is mandatory.

Tipikal na mga Gamit
R5F10DPGJFB ay nararapat para sa 6 aplikasyons: Automotive Low-End Instrument Cluster, HVAC Control Panel with LCD Readout, Automotive Body Controller, Turn-Signal Click Generator, Automotive Stepper-Driven Gauge Module, Automotive Information Display Submodule.
Automotive Low-End Instrument Cluster
The R5F10DPGJFB is purpose-built for automotive low-end instrument clusters (speedometer, tachometer, fuel, temperature gauges). Its four integrated 8-bit stepper motor driver channels drive analog pointer gauges without external driver ICs, while the on-chip sound generator emits turn-signal clicks and warning chimes from 100 Hz to 6 kHz. The 128KB flash accommodates full cluster firmware including gauge calibration, and the AEC-Q100 automotive grade plus -40C to +125C operation handle under-hood thermal stress.
Inirekomenda
HVAC Control Panel with LCD Readout
In automotive HVAC control panels, the R5F10DPGJFB's integrated LCD controller/driver directly drives segment LCDs for temperature and fan-speed readouts, eliminating external LCD driver ICs. The 100-pin LFQFP exposes sufficient GPIO for rotary encoder inputs, button matrices, and backlight PWM control. AEC-Q100 qualification ensures reliable operation across automotive temperature extremes, and the RL78 core's low power consumption supports key-off quiescent current budgets required by body control modules.
Inirekomenda
Automotive Body Controller
The R5F10DPGJFB serves automotive body controllers managing lighting, wipers, and accessory loads, leveraging its 128KB flash for complex state-machine firmware and its UART/CSI/I2C interfaces for LIN/CAN transceivers. The integrated sound generator provides chimes for door/key warnings, and the four stepper channels can drive HVAC blend doors. AEC-Q100 and 3.3V/5V dual-voltage operation suit 12V automotive battery systems with cranking transients.
Inirekomenda
Turn-Signal Click Generator
The R5F10DPGJFB's on-chip sound generator with automatic volume decrement makes it ideal for turn-signal click and warning-tone applications. The 100 Hz to 6 kHz tone range covers all standard automotive chimes, and the volume decrement function provides natural fade-out for indicator clicks. A single MCU replaces discrete tone-generator ICs, reducing BOM and PCB footprint in compact body electronics modules where the 100-pin LFQFP is acceptable.
Inirekomenda
Automotive Stepper-Driven Gauge Module
For standalone gauge modules where multiple analog pointers must be driven with smooth motion, the R5F10DPGJFB's four 8-bit stepper motor drivers deliver microstepping resolution suitable for speedometer and tachometer pointers. The RL78 core handles pointer calibration, nonlinearity correction, and end-stop detection in firmware, freeing the host cluster processor. AEC-Q100 qualification supports under-dash mounting with sustained -40C to +125C exposure.
Inirekomenda
Automotive Information Display Submodule
In distributed cluster architectures, the R5F10DPGJFB powers secondary information display submodules showing trip computer data, gear position, and odometer. Its integrated LCD driver directly addresses segment displays, the RL78 core processes CAN/LIN messages, and the sound generator provides audio feedback for button presses. The 100-pin LFQFP footprint offers abundant GPIO for additional segment expansion and switch-matrix scanning in mid-tier cluster variants.

Talaan ng Disenyo
The 100-pin LFQFP package exposes a thermal pad that should be soldered to a copper pour on the PCB for heat spreading. In automotive instrument cluster environments with sustained -40C to +125C ambient, ensure at least 2 sq cm of 2 oz copper under the exposed pad. Estimated: at full stepper-motor-drive load (4 channels active), internal dissipation remains well under 200 mW thanks to RL78 low-power design, so the LFQFP easily handles thermal stress without a dedicated heatsink.
The R5F10DPGJFB operates from a single 3.3V to 5.5V supply rail. Place a 10 uF bulk capacitor plus a 100 nF decoupling capacitor within 5 mm of the VDD pins to suppress automotive cranking transients (which can dip VBAT below 6V). Use an automotive-qualified LDO such as the NCV4274ADS50R4G upstream. The integrated low-voltage detector (LVD) should be configured in firmware for the lowest acceptable threshold to maximize cold-crank margin.
Route the four stepper motor outputs as differential pairs with at least 0.5 mm spacing to adjacent traces; the 8-bit microstepping PWM edges contain harmonic content that can couple into nearby analog gauge traces. Keep the sound generator PWM output away from LCD segment lines to avoid audible beat frequencies. The 100-pin LFQFP uses 0.5 mm pitch - follow IPC-7351 land pattern guidelines and use NSMD pads with 0.1 mm soldermask expansion for reliable paste release.
Do not assume the R5F10DPGJFB and R5F10DPGCJFB#56 have identical firmware compatibility. Although pinout and major peripheral blocks match, register initialization sequences and timing characteristics may differ across silicon revisions. Always re-run the full instrument cluster validation suite (gauge linearity, LCD contrast, sound tone quality) when migrating firmware to the replacement part. Additionally, do not source from unauthorized brokers claiming 'new old stock' without verifying date codes; Renesas has marked the part obsolete.
