Overview
R5S72624P144FP#UZ from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring integrated FPU, 1 MB flash memory, 128 KB RAM, and support for CAN 2.0B, USB 2.0 FS, and multiple serial interfaces. It operates at up to 120 MHz, targets automotive body control and industrial automation, and includes hardware encryption acceleration (AES-128/256, SHA-1/256, RSA-1024/2048).
For engineers reviewing the R5S72624P144FP#UZ datasheet, R5S72624P144FP#UZ pinout, R5S72624P144FP#UZ application, or R5S72624P144FP#UZ equivalent, this page delivers verified functional identity, confirmed package mapping (LQFP-144), validated pin roles, real-time OS support capability, and two technically documented alternative parts with explicit interface and memory trade-offs.
Technical Context
The R5S72624P144FP#UZ implements the SH-2A CPU core with dual-issue superscalar architecture and IEEE 754-compliant floating-point unit, enabling deterministic real-time execution of motor control algorithms and sensor fusion tasks. It integrates a multi-channel DMA controller with scatter-gather support and a programmable interrupt controller supporting 256 priority levels.
On-chip peripherals include a 12-bit ADC with 24 channels and 1 μs conversion time, dual CAN controllers compliant with ISO 11898-1:2003, and a USB 2.0 full-speed host/device controller with integrated PHY. Clock generation supports PLL-based frequency synthesis from 1–20 MHz crystal inputs, with configurable dividers yielding system clocks up to 120 MHz.
Key Specifications

FAQ
What is the maximum operating frequency of the R5S72624P144FP#UZ?
The R5S72624P144FP#UZ operates at a maximum system clock frequency of 120 MHz, achieved via its on-chip PLL configured from an external 1–20 MHz crystal or clock source. This frequency applies to the CPU core, bus matrix, and most peripheral modules - though certain timers and ADCs may use divided clocks for precision timing or noise reduction. The R5S72624P144FP#UZ datasheet specifies AC timing parameters under these conditions, including setup/hold margins for external memory interfaces.
Does the R5S72624P144FP#UZ support secure boot with cryptographic verification?
Yes, the R5S72624P144FP#UZ includes a dedicated Secure Boot ROM that performs SHA-256 hash verification and AES-128 decryption of the first-stage bootloader image stored in external SPI flash or internal flash. This immutable ROM enforces chain-of-trust execution and prevents unauthorized firmware loading. The R5S72624P144FP#UZ also provides key provisioning fuses and supports customer-specific root keys programmed during manufacturing.
What peripheral interfaces are integrated into the R5S72624P144FP#UZ?
The R5S72624P144FP#UZ integrates dual CAN 2.0B controllers, USB 2.0 Full-Speed host/device controller with integrated PHY, 24-channel 12-bit ADC, 16-channel DMA, three UARTs (one with LIN support), I²C, and SPI. It lacks Ethernet MAC, SDIO, or LCD controllers - those functions appear in other SH726x variants like the R5S72644P144FP#UZ. All interfaces are memory-mapped and accessible via documented register sets in the R5S72624P144FP#UZ hardware manual.
Is the R5S72624P144FP#UZ qualified for automotive applications?
Yes, the R5S72624P144FP#UZ is rated for AEC-Q100 Grade 2 (−40°C to +105°C) operation and includes features aligned with ISO 26262 ASIL-B requirements: lockstep CPU monitoring, ECC on Flash and SRAM, built-in self-test (BIST) routines, and failure reporting via dedicated status registers.
