It operates at up to 120 MHz, includes dual CAN 2.0B controllers, and integrates 12-bit ADC with 24 channels.
For engineers reviewing the R5S72620P144FP#UZ datasheet, R5S72620P144FP#UZ pinout, R5S72620P144FP#UZ application, or R5S72620P144FP#UZ equivalent, key selection criteria include SH-2A instruction set compatibility, on-chip FPU performance for floating-point motion algorithms, dual-CAN interface timing requirements, and LQFP-144 thermal/power delivery constraints in embedded control designs.
Technical Context
The R5S72620P144FP#UZ implements the SH-2A CPU core with 5-stage pipeline, IEEE 754-compliant FPU, and tightly coupled memory architecture. It supports boot modes via dedicated pins (MD0–MD2), includes PLL-based clock generation with programmable dividers (FRQCR register), and features dual independent CAN controllers compliant with ISO 11898-1:2003.
Peripheral integration includes 24-channel 12-bit ADC with sample-and-hold, 32-bit timer/counters with compare-match and PWM output, and DMA controller supporting scatter-gather transfers. The device uses 3.3 V single-supply operation with I/O tolerance to 5 V on selected pins, and supports JTAG debugging via dedicated TCK/TMS/TDI/TDO pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | SuperH™ SH-2A 32-bit RISC, 5-stage pipeline, 120 MHz max operation - enables deterministic real-time execution for motor control loops. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5S72621P144FP#UZ | Same SH-2A core and pinout, but with 256 KB RAM and no FPU - higher memory capacity at cost of floating-point acceleration. | Suitable for integer-only control tasks (e.g., basic PLC logic) where FPU is unused and larger code/data space is required. | Select when application firmware size exceeds 128 KB and floating-point computation is not needed. |
| R5S72640P144FP#UZ | SH-2A core with identical peripheral set, but includes dual USB 2.0 OTG interfaces instead of second CAN controller. | Better suited for human-interface devices (HID), firmware update over USB, or PC-connected test equipment requiring host enumeration. | Choose when USB device/host capability is prioritized over CAN redundancy or fieldbus interoperability. |
Compared with R5S72620P144FP#UZ, R5S72621P144FP#UZ trades FPU for doubled RAM, while R5S72640P144FP#UZ replaces CAN2 with USB OTG - both retain identical LQFP-144 packaging and SH-2A instruction compatibility for seamless migration within Renesas' SH726x ecosystem.

FAQ
What is the maximum operating frequency of the R5S72620P144FP#UZ?
The R5S72620P144FP#UZ operates at a maximum CPU frequency of 120 MHz using its on-chip PLL, which accepts input clocks from 4 to 20 MHz crystals or external oscillators. This frequency is achievable under specified 3.3 V ±0.3 V supply and ambient temperature conditions per the Electrical Characteristics section of the R01UH0134EJ0400 Hardware Manual. The R5S72620P144FP#UZ maintains timing compliance across its full operating range without derating.
Does the R5S72620P144FP#UZ support JTAG debugging?
Yes, the R5S72620P144FP#UZ includes a standard 5-pin JTAG interface (TCK, TMS, TDI, TDO, TRST) compliant with IEEE 1149.1, enabling full boundary-scan testing, real-time trace, and non-intrusive breakpoints. Debug access is available throughout all operational modes including low-power states, and the R5S72620P144FP#UZ supports Renesas E2 emulator and third-party tools compatible with SH-2A core architecture.
What are the key differences between R5S72620P144FP#UZ and R5S72621P144FP#UZ?
The R5S72620P144FP#UZ and R5S72621P144FP#UZ share identical pinout, SH-2A core, and peripheral set except for RAM size and FPU inclusion: R5S72620P144FP#UZ has 128 KB RAM and integrated FPU, whereas R5S72621P144FP#UZ offers 256 KB RAM but omits the FPU. Both use the same LQFP-144 package and are software-compatible for integer-based applications, making R5S72620P144FP#UZ optimal for floating-point-intensive motor control.
Can the R5S72620P144FP#UZ operate with a 5 V input on its I/O pins?
The R5S72620P144FP#UZ uses a 3.3 V core and I/O supply, but selected I/O ports (including PORTA and PORTB) are 5 V tolerant - meaning they accept 0–5 V input signals without damage or level-shifting components. This tolerance applies only to input operation; output voltage swing remains 0–3.3 V. The R5S72620P144FP#UZ datasheet specifies exact pin-by-pin 5 V tolerance in Section 1.5 "Pin Functions" of R01UH0134EJ0400.
Is the R5S72620P144FP#UZ qualified for automotive applications?
The R5S72620P144FP#UZ is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial, office, and communications equipment - not certified for automotive safety-critical systems (e.g., powertrain or ADAS). While it supports CAN 2.0B and operates across extended temperature ranges, it lacks AEC-Q100 qualification and functional safety certification (ISO 26262). For automotive use, Renesas recommends its RH850 or RL78/F1x families instead of the R5S72620P144FP#UZ.
