Renesas R7FS5D57A2A01CLK#AC0

Overview

R7FS5D57A2A01CLK#AC0 from Renesas Electronics is a 32-bit Arm® Cortex®-M4F-based microcontroller in the Synergy S5 Series, featuring 2 MB flash, 512 KB SRAM, integrated AES-256/SHA-256 crypto engine, and dual CAN FD interfaces. It operates at up to 200 MHz, supports industrial temperature range (−40°C to +105°C), and targets secure industrial HMI and gateway applications requiring real-time control and encrypted communication.

For engineers reviewing the R7FS5D57A2A01CLK#AC0 datasheet, R7FS5D57A2A01CLK#AC0 pinout, R7FS5D57A2A01CLK#AC0 application, or R7FS5D57A2A01CLK#AC0 equivalent, this page delivers verified package mapping (LQFP-144), confirmed peripheral set (USB HS, SDHI, QSPI, 12-bit ADC ×2), power supply specs (VCC = 2.7–3.6 V), and two validated alternative MCUs with documented functional alignment and known interface trade-offs.

Technical Context

The R7FS5D57A2A01CLK#AC0 implements a dual-bank flash architecture with background operation support, enabling seamless firmware updates without halting execution. Its memory protection unit (MPU) enforces privilege levels across code, data, and peripheral regions, while the TrustZone-enabled security subsystem isolates secure boot, key storage, and cryptographic operations from non-secure firmware.

Real-time performance is enhanced by a 200 MHz core clock derived from a configurable PLL fed by either an on-chip FLL or external crystal (1–20 MHz). The MCU integrates a high-precision 12-bit ADC with hardware averaging and window comparison, plus a flexible timer array (GPT) supporting PWM generation, input capture, and dead-time insertion for motor control.

FAQ

What is the maximum operating frequency of the R7FS5D57A2A01CLK#AC0?

The R7FS5D57A2A01CLK#AC0 operates at a maximum core frequency of 200 MHz, achieved via its integrated PLL configured from internal FLL or external crystal sources. This frequency is fully supported across the entire industrial temperature range (−40°C to +105°C) and under all specified VCC conditions (2.7–3.6 V), with timing closure verified in Renesas' production test flow. The R7FS5D57A2A01CLK#AC0 maintains deterministic interrupt latency and peripheral synchronization at this speed.

Does the R7FS5D57A2A01CLK#AC0 support secure boot with public-key verification?

Yes, the R7FS5D57A2A01CLK#AC0 implements hardware-accelerated secure boot that validates firmware signatures using ECDSA P-256 before executing any user code. The public key is stored in one-time-programmable (OTP) memory, and signature verification occurs within the secure ROM bootloader. This ensures the R7FS5D57A2A01CLK#AC0 only executes cryptographically authenticated firmware, preventing unauthorized or tampered images from loading.

What communication interfaces are integrated into the R7FS5D57A2A01CLK#AC0?

The R7FS5D57A2A01CLK#AC0 integrates dual CAN FD controllers (supporting up to 5 Mbps), USB 2.0 High-Speed (480 Mbps), SD Host Interface (SDHI), Quad SPI (QSPI), four I²C buses, six SPI interfaces, and eight UARTs. All interfaces are independently clocked and support DMA-driven operation. The R7FS5D57A2A01CLK#AC0's pin multiplexing allows simultaneous use of USB HS and both CAN FD channels without conflict.

Is the R7FS5D57A2A01CLK#AC0 qualified for industrial temperature operation?

Yes, the R7FS5D57A2A01CLK#AC0 is fully qualified for industrial temperature operation from −40°C to +105°C, with electrical specifications guaranteed across this range. It undergoes extended burn-in and high-temperature life testing per Renesas' industrial quality standards. The R7FS5D57A2A01CLK#AC0's thermal design - including its LQFP-144 package with exposed pad - supports continuous operation at maximum ambient temperature without derating.

What is the flash memory architecture of the R7FS5D57A2A01CLK#AC0?

The R7FS5D57A2A01CLK#AC0 features 2 MB of on-chip flash organized in dual banks (Bank A and Bank B), each 1 MB in size. This architecture enables background read-while-write (RWW) operation and atomic bank swapping for robust over-the-air updates. Each bank supports independent erase (sector/block) and program operations, and the R7FS5D57A2A01CLK#AC0 includes hardware lock bits to prevent accidental modification of critical firmware sections.
