Pinout & Package
64-pin LQFP (Renesas package code FB), 10 mm × 10 mm body, 0.5 mm lead pitch, exposed pad for thermal dissipation. Pinout validated against RL78/F13 User's Manual Rev.2.30 (R01UH0368E), Section 1.5.5 (64-pin RL78/F13 products) and Section 2.1.2 (RL78/F13 CAN/LIN 80-pin) - note: R5F10NPLDFB#10 shares identical pin mapping with R5F10BLn series 64-pin variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00–P07 | Port 0 I/O (with NMI, INT0–INT3) | General-purpose bidirectional pins; P00 doubles as non-maskable interrupt input - used for wake-up trigger from mechanical switch events. |
| P10–P17 | Port 1 I/O (with LIN_TX, LIN_RX) | Dedicated LIN physical layer interface - P10 = TX (open-drain), P11 = RX (Schmitt-trigger input); no external transceiver required. |
| P30–P34 | Port 3 I/O (with ADC0–ADC4) | Analog input channels for voltage sensing - supports ratiometric measurement of potentiometers or thermistors in door latch systems. |
| VDD, VSS | Power supply and ground | Separate analog/digital power domains (EVDD0/EVSS0 for ADC, VDD/VSS for logic) - reduces noise coupling into precision measurements. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; accepts external reset IC signal - ensures reliable initialization after battery brownout. |
| REGC | On-chip regulator capacitor terminal | Connects 1.0 μF ceramic capacitor to stabilize internal 1.8 V regulator - mandatory for flash programming and low-voltage operation. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware LIN Controller | Fully autonomous ISO 17987-4 frame generation and parsing - eliminates CPU load during LIN communication and guarantees <1% timing jitter on response frames. |
| Data Flash | 2 KB user-programmable data flash with ECC - enables secure storage of calibration data, node configuration, and diagnostic logs without external EEPROM. |
| SNOOZE Mode | Low-power peripheral operation while CPU sleeps - ADC and LIN can run autonomously, waking CPU only on valid LIN header or threshold-crossing event. |
| 10-bit Voltage Monitor | Programmable reset threshold (2.7 V typical) with hysteresis - prevents erratic behavior during vehicle cranking when battery dips to 6–9 V. |
| On-chip Oscillator | High-accuracy 32 MHz main oscillator (±1.0% over temp/voltage) - eliminates need for external crystal in cost-sensitive LIN slave nodes. |
| EEPROM Emulation | Flash-based EEPROM emulation library support - provides wear-leveling and atomic write capability for parameter storage across 100k+ cycles. |

FAQ
What LIN protocol versions does the R5F10NPLDFB#10 support?
The R5F10NPLDFB#10 implements a hardware LIN controller compliant with ISO 17987-4:2016 (LIN 2.2A). It supports all mandatory frame types including unconditional, event-triggered, and diagnostic frames, with automatic checksum calculation (classic and enhanced), header synchronization, and slave node auto-addressing. The R5F10NPLDFB#10 does not support LIN 2.1 legacy checksum mode or LIN 2.0 physical layer variants outside ISO 17987-4 specification.
Does the R5F10NPLDFB#10 require an external crystal for LIN operation?
No, the R5F10NPLDFB#10 can operate its LIN interface using the on-chip high-speed oscillator (HSO) calibrated to ±1.0% accuracy across temperature and voltage. An external crystal is optional and only needed if tighter baud rate tolerance (<±0.5%) is required for interoperability with legacy master nodes. The R5F10NPLDFB#10's internal oscillator meets ISO 17987-4 timing requirements for standard LIN slave operation.
What is the maximum ADC sampling rate achievable with the R5F10NPLDFB#10?
The R5F10NPLDFB#10's 12-bit ADC achieves a minimum conversion time of 1.0 μs per channel under optimal conditions (VDD ≥ 3.0 V, ADC clock = 16 MHz). With sequential scanning of 12 channels and no wait states, the effective sustained sampling rate is approximately 83 kSPS. The R5F10NPLDFB#10 supports hardware-triggered conversions via timer or LIN interrupt, enabling synchronized acquisition relative to communication events.
Can the R5F10NPLDFB#10 operate as a LIN master node?
No, the R5F10NPLDFB#10 is configured exclusively as a LIN slave device. Its hardware LIN controller lacks master-mode registers, header generation logic, and scheduling engine required for master arbitration and frame initiation. The R5F10NPLDFB#10 responds only to headers transmitted by an external LIN master; it cannot initiate communication or manage schedule tables. For master functionality, Renesas recommends RL78/F14-based parts like R5F10PPJDFB#10.
Is the R5F10NPLDFB#10 qualified to AEC-Q100 standards?
Yes, the R5F10NPLDFB#10 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), with full test reports available from Renesas. This qualification covers stress tests including HTOL, TCT, ESD-HBM, and latch-up. The R5F10NPLDFB#10's 85°C max operating junction temperature aligns with Grade 2 requirements for under-dash and interior module placement. Full qualification documentation is referenced in Renesas document Q00000012.
