For engineers reviewing the R5S72624W144FP#U0 datasheet, R5S72624W144FP#U0 pinout, R5S72624W144FP#U0 application, or R5S72624W144FP#U0 equivalent, key selection considerations include SH-2A instruction set compatibility, 144-pin LQFP mechanical footprint, CAN/ADC peripheral integration, and industrial-grade temperature range (−40°C to +85°C) per Renesas Standard quality grade.

Technical Context

The R5S72624W144FP#U0 implements the SH-2A CPU core with dual-issue superscalar architecture, supporting both integer and IEEE 754-compliant single/double-precision floating-point operations via dedicated FPU. It integrates a programmable clock pulse generator with PLL, enabling configurable system clocks up to 120 MHz.

On-chip peripherals include a 32-bit timer with compare match and capture functions, watchdog timer with windowed operation, and interrupt controller supporting 256 vector entries. Memory protection unit (MPU) enforces privilege-level access control across Flash, RAM, and peripheral address spaces.

FAQ

What is the maximum operating frequency of the R5S72624W144FP#U0?

The R5S72624W144FP#U0 operates at a maximum system clock frequency of 120 MHz, achieved via its on-chip PLL clock pulse generator locked to an external crystal or clock source. This frequency applies to the SH-2A CPU core, FPU, and most peripheral modules - confirmed in Section 5.3 "Clock Operating Modes" of the Hardware User's Manual Rev. 4.00. The R5S72624W144FP#U0 maintains timing integrity across all voltage and temperature ranges specified for industrial use.

Does the R5S72624W144FP#U0 support CAN FD?

No, the R5S72624W144FP#U0 implements two CAN 2.0B controllers only - not CAN FD. Its CAN modules comply with ISO 11898-1:2003 and support bit rates up to 1 Mbps, message filtering, and FIFO buffering. CAN FD capability is introduced in the SH7264 series variant R5S72644W144FP#U0, while the R5S72624W144FP#U0 remains optimized for legacy CAN 2.0B networks in industrial machinery and motor drives.

What debug interface does the R5S72624W144FP#U0 provide?

The R5S72624W144FP#U0 features a standard JTAG-based on-chip debug interface compliant with IEEE 1149.1, supporting full visibility into CPU registers, memory, and peripheral states during development. It is compatible with Renesas E20 emulator and third-party debug tools using the standard 14-pin JTAG connector layout defined in Section 1.4 "Pin Assignment" of the Hardware User's Manual. This interface enables real-time trace, hardware breakpoints, and non-intrusive firmware validation for the R5S72624W144FP#U0.

Is the R5S72624W144FP#U0 qualified for automotive applications?

No, the R5S72624W144FP#U0 is designated as a "Standard" quality grade product per Renesas documentation, intended for industrial, office, and consumer equipment - not transportation or safety-critical systems. It is rated for −40°C to +85°C operation and lacks AEC-Q100 qualification, diagnostic coverage, or ASIL-targeted features. For automotive use, Renesas offers separate "High Quality" grade devices such as RH850 family members - the R5S72624W144FP#U0 is not suitable for automotive ECUs or ADAS subsystems.

How much user-accessible Flash and RAM does the R5S72624W144FP#U0 include?

The R5S72624W144FP#U0 provides 1 MB of on-chip Flash memory with built-in ECC for program storage and 128 KB of SRAM with parity checking for data and stack usage. Both memories are directly accessible by the SH-2A core without wait states at maximum frequency. These capacities are fixed for this variant - other members of the SH7262 group (e.g., R5S72623W144FP#U0) offer reduced memory sizes, but the R5S72624W144FP#U0 delivers the full 1 MB/128 KB configuration as specified in Section 1.1 "SH7262/7264 Features" of the Hardware User's Manual.
