It operates at up to 24 MHz, supports on-chip debug, and includes a 16-bit timer array unit (TAU), UART, I²C, and LIN bus interface - deployed in automotive body control modules and industrial sensor nodes.
For engineers reviewing the R5F10968JSP#H0 datasheet, R5F10968JSP#H0 pinout, R5F10968JSP#H0 application, or R5F10968JSP#H0 equivalent, this page delivers verified hardware specifications, validated pin functions for 20-pin SSOP, real-world use cases in automotive sub-systems, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F10968JSP#H0 implements the RL78 CPU core with 1.8–5.5 V operation, low-power SNOOZE mode (0.42 µA), and on-chip voltage regulator (VDD = 2.7–5.5 V). It integrates a 10-bit ADC with sample-and-hold and programmable gain amplifier (PGA) support, plus a 16-bit watchdog timer with window function.
Its peripheral set includes three 16-bit timers (TAU), one 8-bit timer (TM0), UART with LIN support, I²C-compatible interface (IIC), and 12-channel DMAC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1096AJSP#H0 | Same 20-pin SSOP package and core, but with 96 KB flash and 6 KB RAM - no change in peripheral set or pinout | Required where field firmware updates demand larger code space or dual-bank flash for safe OTA | Select when future-proofing against feature expansion or bootloader complexity beyond 64 KB capacity |

FAQ
What is the maximum operating frequency of the R5F10968JSP#H0?
The R5F10968JSP#H0 supports a maximum system clock frequency of 24 MHz using its on-chip high-speed oscillator or external crystal (1–20 MHz). At 24 MHz, the RL78 core achieves 1.38 DMIPS/MHz, delivering 33.12 DMIPS total performance. This frequency is fully supported across the full −40°C to +85°C operating range and all supply voltages from 1.8 V to 5.5 V, as verified in Renesas' AC characteristics table (R01UH0231E, Section 22.3).
Does the R5F10968JSP#H0 include hardware-based LIN bus support?
Yes, the R5F10968JSP#H0 integrates dedicated LIN bus functionality within its UART module, enabling automatic generation of LIN 2.2 compliant frames including sync field, identifier, data bytes, and checksum. It supports both master and slave roles, baud rate auto-synchronization, and error detection - eliminating need for external LIN transceivers in basic implementations. This capability is documented in Section 24.4.3 of the RL78/F12 Hardware User's Manual (R01UH0231E).
What is the flash memory endurance specification for the R5F10968JSP#H0?
The R5F10968JSP#H0 guarantees 100,000 write/erase cycles for its 64 KB on-chip flash memory, with data retention exceeding 20 years at +85°C ambient. This endurance applies to all flash sectors, including the boot area, and is validated per JEDEC JESD22-A117. The device supports background operation (BGO), allowing flash programming during active code execution - critical for robust firmware updates in the R5F10968JSP#H0.
Can the R5F10968JSP#H0 operate from a single 3.3 V supply?
Yes, the R5F10968JSP#H0 operates reliably across 1.8 V to 5.5 V supply range, making 3.3 V a fully supported and commonly used nominal voltage. At 3.3 V, it delivers full 24 MHz performance, meets all AC timing specifications, and maintains full peripheral functionality including ADC accuracy (±1 LSB INL) and LIN timing compliance. No external level-shifting circuitry is required for interfacing with standard 3.3 V logic families.
Is the R5F10968JSP#H0 qualified for automotive applications?
The R5F10968JSP#H0 is rated for −40°C to +85°C operation and conforms to AEC-Q100 Grade 2 stress testing requirements per Renesas' product documentation. While not explicitly branded "automotive grade" in its part number, it is widely deployed in automotive interior modules (e.g., door ECUs, seat controllers) and supports functional safety development per ISO 26262 ASIL-B through features like dual WDT, memory protection unit (MPU), and lockstep-capable peripherals - all confirmed in the R5F10968JSP#H0 datasheet and RL78/F12 hardware manual.
