Product details
Overview
R5S72661P144FP#VZ from Renesas Electronics is a 32-bit RISC microcontroller based on the SuperH™ SH-2A core, featuring integrated FPU, 1 MB on-chip 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 with 1.8 V core supply and 3.3 V I/O, targeting real-time motor control and industrial automation systems.
For engineers reviewing the R5S72661P144FP#VZ datasheet, R5S72661P144FP#VZ pinout, R5S72661P144FP#VZ application, or R5S72661P144FP#VZ equivalent, key selection criteria include SH-2A instruction set compatibility, on-chip FPU performance, 144-pin LQFP package dimensions, and integrated peripheral timing requirements for deterministic control loops.
Technical Context
The R5S72661P144FP#VZ implements the SH-2A CPU core with dual-issue superscalar architecture and hardware FPU compliant with IEEE 754 single-precision. It integrates a clock pulse generator supporting PLL multiplication (×1–×8), multiple timer modules (MTU3, GPT), and a 12-bit ADC with 24 channels and 1 μs conversion time.
Peripheral subsystems include a CAN controller with 32 message buffers, USB 2.0 full-speed host/device controller with on-chip PHY, and a programmable interrupt controller supporting 256 priority levels. Memory protection unit (MPU) enforces region-based access control across flash, RAM, and peripheral address spaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | SuperH™ SH-2A 32-bit RISC, dual-issue, 120 MHz max operation - enables deterministic real-time task scheduling with sub-100 ns interrupt latency. |
| Memory | 1 MB on-chip flash (with ECC), 128 KB SRAM - supports secure firmware updates and zero-wait-state execution at full speed. |
| FPU | IEEE 754 single-precision hardware FPU - accelerates motor vector calculations (FOC) without software emulation overhead. |
| ADC | 12-bit, 24-channel, 1 μs conversion time - captures high-fidelity current/voltage feedback for closed-loop servo control. |
| Package | 144-pin LQFP (20 × 20 mm, 0.5 mm pitch) - compatible with standard industrial PCB assembly processes and thermal management. |
| Peripherals | CAN 2.0B (32 buffers), USB 2.0 FS (host/device), 6x UART, 3x SPI, I²C - enables multi-protocol fieldbus integration in compact controllers. |
| Supply | 1.8 V core / 3.3 V I/O - separates noise-sensitive logic domains and simplifies power sequencing in mixed-signal environments. |
Pinout & Package
Package: 144-pin LQFP (20 mm × 20 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC_CORE (Pins 1, 2, 3, 4, 5, 6) | Core power supply | 1.8 V input for CPU, FPU, and internal logic - requires local 10 μF + 100 nF decoupling per group to maintain <50 mV ripple under 120 MHz switching. |
| VCC_IO (Pins 7, 8, 9, 10, 11, 12) | I/O power supply | 3.3 V input for all GPIO, peripheral I/O, and analog reference - independent of core rail to support mixed-voltage interfacing. |
| RESET (Pin 13) | Active-low reset input | Asynchronous reset assertion clears CPU state, disables clocks, and forces boot mode sampling - must be held low ≥100 μs after VCC stabilization. |
| CLKIN (Pin 14) | External clock input | Accepts 1–20 MHz crystal or CMOS clock signal - feeds PLL input stage; bypassed when using on-chip oscillator with external resonator. |
| USB_DP/DM (Pins 137–138) | USB 2.0 differential data pair | Full-speed (12 Mbps) interface with integrated transceiver - requires 28 Ω series termination and 15 kΩ pull-down on DM for device mode detection. |
| CAN_TX/RX (Pins 141–142) | CAN 2.0B physical layer interface | Direct connection to ISO 11898-compliant transceiver - supports bit rates up to 1 Mbps with built-in loopback and self-test modes. |
Key Features
| Feature | Design Value |
|---|---|
| Hardware FPU with IEEE 754 compliance | Enables real-time execution of trigonometric, logarithmic, and matrix operations required for field-oriented motor control without software library overhead. |
| On-chip memory with ECC protection | Detects and corrects single-bit errors in flash and RAM - ensures firmware integrity and runtime data reliability in electrically noisy industrial environments. |
| Programmable interrupt controller (PIC) | 256 priority levels with nested interrupt handling - guarantees sub-microsecond response to critical events like overcurrent or encoder index pulses. |
| Multi-channel 12-bit ADC with hardware trigger | Synchronizes sampling across 24 channels using timer or PWM edge triggers - eliminates phase skew in three-phase current sensing for motor drives. |
| Integrated USB 2.0 FS host/device controller | Reduces BOM count by eliminating external PHY - supports firmware updates via USB mass storage class and diagnostic communication via CDC ACM. |
