Product details
Overview
R5F1096EKSP#H0 from Renesas Electronics is a 16-bit RL78/F12 microcontroller in a 20-pin SSOP package, featuring 32 KB flash memory, 2.5 KB RAM, and integrated 10-bit ADC with 8 channels. 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 R5F1096EKSP#H0 datasheet, R5F1096EKSP#H0 pinout, R5F1096EKSP#H0 application, or R5F1096EKSP#H0 equivalent, key selection criteria include its 20-pin SSOP footprint, 32 KB flash/2.5 KB RAM allocation, LIN-capable UART, 10-bit ADC resolution with sample-and-hold, and compliance with AEC-Q100 Grade 2 for under-hood automotive use.
Technical Context
The R5F1096EKSP#H0 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.8–5.5 V operation and ultra-low-power modes (HALT, STOP, SNOOZE) down to 0.52 µA in STOP mode. Its peripheral set includes a 16-bit timer array unit (TAU) with 32-bit PWM capability, a 10-bit ADC with internal reference voltage (1.45 V), and a LIN transceiver compliant with ISO 17987-4:2016.
It integrates a programmable low-voltage detection (LVD) circuit with 4 selectable thresholds (2.4 V to 4.2 V), a hardware watchdog timer (WDT), and a real-time clock (RTC) with calendar function - all operating independently of main CPU clock via sub-clock oscillator (32.768 kHz).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F1096GKSP#H0 | Same package and pinout; 48 KB flash, 4 KB RAM - no change to PCB layout or firmware binary compatibility. | Required when firmware size exceeds 32 KB or additional RAM buffers needed for CAN/LIN gateway logic. | Select if future firmware growth headroom or dual-protocol (LIN + CAN FD) support is anticipated. |
| MC9S08AC128CPUE | 8-bit S08 core, 128 KB flash, 8 KB RAM, 12-bit ADC - different architecture, instruction set, and peripheral register map. | Suitable for legacy S08-based designs undergoing minimal rework; lacks integrated LIN PHY and RTC calendar. | Choose only for drop-in replacement in existing S08 platforms where toolchain and certification reuse outweigh performance trade-offs. |
Compared with R5F1096GKSP#H0, the R5F1096EKSP#H0 offers optimal cost/performance balance for LIN-only nodes with <32 KB code; versus MC9S08AC128CPUE, it delivers higher MIPS/Watt, native LIN compliance, and smaller die size - reducing BOM count and thermal footprint.

FAQ
What is the maximum operating frequency of the R5F1096EKSP#H0?
The R5F1096EKSP#H0 operates at a maximum CPU frequency of 24 MHz using its high-speed on-chip oscillator or an external crystal. This frequency is fully supported across the full 1.8–5.5 V supply range and −40 °C to +105 °C temperature range, enabling deterministic real-time response in automotive and industrial control loops. The R5F1096EKSP#H0 achieves 1.62 DMIPS/MHz at this speed.
Does the R5F1096EKSP#H0 include an integrated LIN physical layer?
No, the R5F1096EKSP#H0 integrates a LIN protocol controller and UART with auto-baud detection and checksum handling, but requires an external LIN transceiver (e.g., TLE7259-3GE) for physical layer signaling. Its UART peripheral is configured to meet ISO 17987-4:2016 timing requirements, and the R5F1096EKSP#H0's internal clock accuracy (±1 %) satisfies LIN master/slave tolerance without trimming.
What debug interface does the R5F1096EKSP#H0 support?
The R5F1096EKSP#H0 supports Renesas' single-wire debug (SWD) interface via the RES# pin - eliminating the need for dedicated debug headers or JTAG pins. This interface enables full in-circuit programming, real-time variable monitoring, and breakpoint execution without modifying the 20-pin SSOP footprint. Debug access remains functional even in HALT and STOP low-power modes.
Is the R5F1096EKSP#H0 qualified for automotive applications?
Yes, the R5F1096EKSP#H0 is AEC-Q100 qualified to Grade 2 (−40 °C to +105 °C), making it suitable for passenger compartment and under-hood automotive applications including door modules, seat controls, and lighting systems. Its qualification covers stress testing for temperature cycling, humidity bias, ESD, and mechanical shock - verified per the official Renesas RL78/F12 datasheet and qualification report.
How much user-accessible RAM does the R5F1096EKSP#H0 provide?
The R5F1096EKSP#H0 provides 2.5 KB of on-chip SRAM, all accessible to user firmware without reservation for system use. Of this, 2 KB is retained in STOP mode with RTC active, while the remaining 512 B is automatically cleared on wake-up. This allocation supports real-time buffering of sensor data, LIN message queues, and stack usage for RTOS tasks in resource-constrained nodes.
