Overview
R5S72645P144FP#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 R5S72645P144FP#UZ datasheet, R5S72645P144FP#UZ pinout, R5S72645P144FP#UZ application, or R5S72645P144FP#UZ equivalent, key selection criteria include SH-2A FPU performance, 144-pin LQFP package compatibility, CAN+USB co-integration, flash security features, and AEC-Q100 Grade 2 qualification for under-hood automotive use.
Technical Context
The R5S72645P144FP#UZ implements the SH-2A CPU core with dual-issue superscalar architecture, 32-bit integer ALU, and IEEE 754-compliant single/double-precision FPU. It integrates a multi-channel DMA controller supporting scatter-gather transfers and peripheral-to-memory burst transfers without CPU intervention.
On-chip peripherals include a 12-bit ADC with 24 channels and 1 μs conversion time, a 32-bit timer with quadrature encoder input, and a programmable watchdog timer with windowed operation. The clock system supports PLL multiplication (up to 120 MHz), external crystal (4–20 MHz), and internal RC oscillator fallback.
