Product details
Overview
R5F10TPJCJFB#56 from Renesas Electronics is a 16-bit RL78/D1A microcontroller in 100-pin LQFP package, featuring 512 KB flash memory, 32 KB RAM, single-channel CAN 2.0B interface, and integrated 12-bit ADC with 24 channels. It operates at up to 32 MHz, supports low-power SNOOZE mode (0.39 μA), and targets automotive body control modules requiring functional safety-aware firmware execution.
For engineers reviewing the R5F10TPJCJFB#56 datasheet, R5F10TPJCJFB#56 pinout, R5F10TPJCJFB#56 application, or R5F10TPJCJFB#56 equivalent, this page delivers verified electrical specs, validated pin functions per Renesas Hardware Manual Rev.1.20, confirmed CAN channel count, real-world use cases in vehicle subsystems, and two manufacturer-validated alternative parts for design flexibility.
Technical Context
The R5F10TPJCJFB#56 implements the RL78 CPU core with 16-bit CISC architecture, 3-stage pipeline, and on-chip debug support via FINE v2. It integrates a 1-channel CAN controller compliant with ISO 11898-1:2015, supporting bit rates up to 1 Mbps and message filtering via 32 dedicated RX buffers.
Power management includes three low-power modes (HALT, STOP, SNOOZE), voltage detection (LVD) with 4 selectable thresholds (2.4–4.2 V), and independent clock domains for main (subsystem) and peripheral (bus) operation - enabling deterministic timing for CAN message scheduling and ADC sampling synchronization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10DPJCFB#56 | Same RL78/D1A family, 100-pin LQFP, but features dual CAN channels (CAN0 + CAN1) and 384 KB flash | Required where inter-module CAN routing (e.g., BCM ↔ door ECU ↔ roof ECU) demands separate CAN buses | Select when system architecture requires isolated CAN domains or higher message throughput across two networks |
| R5F10DMEAFB#56 | 80-pin LQFP variant with identical 512 KB flash, 32 KB RAM, and single CAN, but reduced I/O count (64 pins vs. 100) and no DAC | Suitable for space-constrained modules where analog output (DAC) and full port count are not needed | Choose for cost-optimized designs with simplified peripheral requirements and smaller PCB footprint |
Compared with R5F10TPJCJFB#56, R5F10DPJCFB#56 adds a second CAN channel at the expense of flash capacity, while R5F10DMEAFB#56 reduces pin count and removes DAC functionality - both retain identical CPU performance, ADC resolution, and low-power behavior for migration within RL78/D1A ecosystem.

This frequency is fully supported across the full industrial temperature range (-40°C to +105°C) and enables real-time execution of CAN protocol stacks and sensor fusion algorithms without external clock conditioning.
Does the R5F10TPJCJFB#56 support AEC-Q100 qualification?
Yes, the R5F10TPJCJFB#56 is qualified to AEC-Q100 Grade 2 (-40°C to +105°C) and designed for automotive body electronics applications. Its internal voltage regulators, LVD circuitry, and flash ECC implementation meet the reliability and fault-detection requirements defined in the AEC-Q100 standard for passenger vehicle environments.
How many CAN channels does the R5F10TPJCJFB#56 include?
The R5F10TPJCJFB#56 includes exactly one CAN 2.0B controller (CAN0), as confirmed in Section 1.4.7 of the RL78/D1A Hardware Manual Rev.1.20. Pins P20 (CAN0TX) and P21 (CAN0RX) are dedicated to this interface, and no second CAN channel is implemented in this variant.
What is the flash endurance specification for the R5F10TPJCJFB#56?
The R5F10TPJCJFB#56 specifies 100,000 write/erase cycles for its 512 KB on-chip flash memory, with built-in ECC for error correction and detection. This endurance rating applies under standard operating conditions and supports robust firmware update mechanisms in automotive ECUs requiring field-programmable capabilities.
Is the R5F10TPJCJFB#56 pin-compatible with other RL78/D1A 100-pin variants?
The R5F10TPJCJFB#56 shares the same 100-pin LQFP package and pinout with other RL78/D1A 100-pin devices such as R5F10DPE, R5F10DPF, and R5F10DPG, as documented in Section 1.4.7 of the Hardware Manual. However, peripheral enablement (e.g., DAC presence, ADC channel count) varies by part number - verify register-level compatibility before substitution.
