For engineers reviewing the R5S72623P144FP#UZ datasheet, R5S72623P144FP#UZ pinout, R5S72623P144FP#UZ application, or R5S72623P144FP#UZ equivalent, key selection criteria include SH-2A instruction set compatibility, on-chip FPU support for floating-point math-intensive control loops, 144-pin LQFP mechanical footprint, and CAN + USB + Ethernet peripheral integration for industrial connectivity.

Technical Context

The R5S72623P144FP#UZ 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 hardware. It integrates a 32-bit bus interface, on-chip debug support (JTAG), and configurable interrupt controller with 256 vector entries.

Hardware peripherals include three 32-bit timer units (each with compare match, input capture, and PWM output), a 12-bit 16-channel ADC with simultaneous sampling capability, and dual CAN controllers compliant with ISO 11898-1:2003. Clock generation uses PLL-based frequency synthesis with selectable input sources (crystal, external clock, or internal oscillator).

FAQ

What is the maximum operating frequency of the R5S72623P144FP#UZ?

The R5S72623P144FP#UZ operates at a maximum CPU frequency of 200 MHz using its on-chip PLL, which accepts input clocks from 1 MHz to 20 MHz and supports programmable multiplication ratios. This frequency is guaranteed across the full −40°C to +85°C temperature range and 2.7 V to 3.6 V supply voltage, as verified in the Electrical Characteristics section of the R01UH0134EJ0400 Hardware Manual.

Does the R5S72623P144FP#UZ support CAN FD or only classical CAN 2.0B?

The R5S72623P144FP#UZ supports only CAN 2.0B (ISO 11898-1:2003) with bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate, extended data length, or CRC enhancements. The two integrated CAN controllers are fully compatible with legacy CAN networks and support message filtering, mailbox buffering, and error confinement per the SH7260 Series specification.

Is the R5S72623P144FP#UZ pin-compatible with other members of the SH7262 group?

Yes, the R5S72623P144FP#UZ shares identical pin assignment, electrical characteristics, and package (144-pin LQFP) with other SH7262 variants including R5S72620 through R5S72627. All share the same pin functions defined in Section 1.4 "Pin Assignment" and Section 1.5 "Pin Functions" of the R01UH0134EJ0400 manual, enabling hardware reuse across firmware variants.

What debug interfaces are supported by the R5S72623P144FP#UZ?

The R5S72623P144FP#UZ supports IEEE 1149.1 JTAG for boundary-scan testing and on-chip debugging, including real-time trace, hardware breakpoints, and watchpoints. It does not support SWD or cJTAG. Debug access requires a Renesas E2 emulator or compatible JTAG probe, and the JTAG TCK/TMS/TDI/TDO pins are assigned to dedicated package pins as documented in the Hardware Manual's Pin Function table.

Does the R5S72623P144FP#UZ include hardware encryption accelerators?

No, the R5S72623P144FP#UZ does not include dedicated hardware encryption accelerators such as AES, SHA, or RSA engines. Security functions rely on software libraries executed on the SH-2A core. For applications requiring cryptographic acceleration, Renesas recommends the RA6M5 or RX72M families, which integrate TRNG and crypto accelerators - the R5S72623P144FP#UZ focuses on real-time control performance rather than security offload.
