Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5S72642P144FP#UZ | Same SH-2A core and peripheral set, but with 2 MB flash and 256 KB RAM - no change in pinout or clock architecture. | Required when firmware image size exceeds 1 MB or extended data buffering is needed for logging or OTA staging. | Select R5S72642P144FP#UZ only if additional flash/RAM headroom is confirmed necessary; identical layout and driver compatibility. |
| R5F566TEADFP#30 | RX66T 32-bit core (not SH-2A), 160 MHz, 1 MB flash, 256 KB RAM, no integrated CAN PHY - requires external CAN transceivers. | Better suited for high-performance motor control with advanced PWM timers; lacks native USB device mode and SH-2A FPU instruction set. | Choose R5F566TEADFP#30 for new designs prioritizing higher PWM resolution and IEC 61508 SIL2 certification path over legacy SH software reuse. |
Compared with R5S72641P144FP#UZ, R5S72642P144FP#UZ offers scalable memory without layout changes, while R5F566TEADFP#30 trades SH-2A compatibility for RX-family safety features and higher PWM precision - making the former ideal for cost-sensitive incremental upgrades and the latter for safety-critical greenfield designs.

This frequency is sustained across the full −40°C to +85°C industrial temperature range, as verified in Renesas' electrical characteristics table (Section 8 of R01UH0134EJ0400).
Does the R5S72641P144FP#UZ support USB device mode without external components?
Yes, the R5S72641P144FP#UZ integrates a full-speed USB 2.0 PHY with an internal 1.5 kΩ pull-up resistor on the USBDP pin, enabling USB device enumeration without external resistors or transceivers. The USB controller supports control/bulk/interrupt endpoints and complies with USB 2.0 specification for device-mode operation.
Is the R5S72641P144FP#UZ pin-compatible with other SH7264 Group members?
Yes, the R5S72641P144FP#UZ shares identical 144-pin LQFP mechanical and electrical pinout with all SH7264 Group variants (e.g., R5S72640, R5S72642, R5S72643), including matching power, ground, clock, CAN, USB, and ADC pin assignments - enabling direct PCB reuse across memory/configurations.
What debug interface does the R5S72641P144FP#UZ support?
The R5S72641P144FP#UZ supports Renesas' E10A-USB and E20 debug interfaces via the dedicated SWD/JTAG pins (TRST#, TMS, TCK, TDI, TDO). It is fully compatible with Renesas' CS+ and e2 studio IDEs, enabling real-time debugging, flash programming, and trace analysis without requiring external debug probes beyond standard Renesas tools.
How is flash security implemented on the R5S72641P144FP#UZ?
The R5S72641P144FP#UZ implements flash security through three mechanisms: (1) Read-out protection bits that disable external debugger access to flash contents, (2) Secure boot loader verifying SHA-256/RSA-2048 signatures before firmware execution, and (3) Flash lock bits preventing accidental erase/write during runtime - all configurable via dedicated system control registers.
