Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F57266ADFP#30 | Same SH-2A core, 512 KB flash, no FPU, USB HS support - lower cost, reduced math capability. | Suitable for non-math-intensive CAN gateways or simple I/O concentrators without floating-point control. | Select when FPU and >512 KB flash are not required; saves ~18% BOM cost in volume production. |
| RA6M5GFP#AA0 | Arm Cortex-M33 core, 1 MB flash, TrustZone, no CAN FD - newer architecture, different toolchain, no SH legacy compatibility. | Better for new designs requiring PSA Certified security, BLE coexistence, or cloud connectivity stacks. | Choose for greenfield projects prioritizing Arm ecosystem, long-term roadmap, and certified security over SH code reuse. |
Compared with R5S72627P144FP#UZ, R5F57266ADFP#30 offers cost savings at the expense of FPU and memory headroom, while RA6M5GFP#AA0 provides modern security and connectivity but requires full firmware re-architecture and toolchain migration.

FAQ
What is the maximum operating frequency of the R5S72627P144FP#UZ?
The R5S72627P144FP#UZ operates at a maximum CPU frequency of 120 MHz, achieved via its on-chip PLL with configurable multiplication/division ratios. This frequency is guaranteed across the full industrial temperature range (−40°C to +105°C) under specified VCC conditions, and enables deterministic execution of real-time control tasks such as motor commutation and CAN message scheduling in the R5S72627P144FP#UZ.
Does the R5S72627P144FP#UZ support functional safety certification?
Yes, the R5S72627P144FP#UZ includes hardware features aligned with ISO 26262 ASIL-B requirements, including dual-lockstep CPU mode, memory BIST, windowed watchdog timer, and error-correcting code for flash. Renesas provides safety manuals and FMEDA reports for the R5S72627P144FP#UZ, enabling integration into automotive body control modules certified to ASIL-B.
Can the R5S72627P144FP#UZ operate without an external crystal?
Yes, the R5S72627P144FP#UZ can operate using its internal high-speed oscillator (HOCO) at 20 MHz or low-speed oscillator (LOCO) at 32.768 kHz for basic initialization and low-power modes. However, for CAN 2.0B bit timing accuracy (±1% tolerance) and USB 2.0 FS compliance, an external crystal (typically 12 MHz or 20 MHz) connected to EXTAL/XTAL pins is required - the R5S72627P144FP#UZ does not support USB or CAN without it.
How many CAN interfaces does the R5S72627P144FP#UZ integrate?
The R5S72627P144FP#UZ integrates two independent CAN 2.0B controllers with dedicated TX/RX pins (CAN0TX/CAN0RX and CAN1TX/CAN1RX), each supporting bit rates up to 1 Mbps and message filtering via 64-entry acceptance filters. These controllers operate autonomously with DMA support, allowing the R5S72627P144FP#UZ to serve as a dual-bus automotive gateway or redundant industrial fieldbus node.
Is the R5S72627P144FP#UZ pin-compatible with other SH726x series MCUs?
No, the R5S72627P144FP#UZ is not pin-compatible with earlier SH726x variants such as R5S72620 or R5S72621 due to differences in peripheral mapping, power domain assignments, and pin multiplexing. While all SH7262/7264 Group devices share the same 144-pin LQFP footprint, the R5S72627P144FP#UZ has unique pin functions for USB, FPU debug, and enhanced CAN routing - PCB layout must be designed specifically for the R5S72627P144FP#UZ.
