Product details
Overview
R7FS1JA782A01CBT#BC0 from Renesas Electronics is a 32-bit Arm® Cortex®-M23-based microcontroller in the Synergy S1JA Group, featuring 512 KB flash, 128 KB SRAM, and integrated AES-256/SHA-256 cryptographic accelerators. It operates at up to 48 MHz, supports 1.6–5.5 V supply, and targets secure industrial sensing and HMI edge nodes with its configurable analog front-end and USB 2.0 FS interface.
For engineers reviewing the R7FS1JA782A01CBT#BC0 datasheet, R7FS1JA782A01CBT#BC0 pinout, R7FS1JA782A01CBT#BC0 application, or R7FS1JA782A01CBT#BC0 equivalent, key selection criteria include its TrustZone-enabled security architecture, 12-bit ADC with hardware averaging, dual CAN FD support (via external transceiver), and QFN-64 package with 52 GPIOs - all validated for IEC 61508 SIL-2 functional safety compliance.
Technical Context
The R7FS1JA782A01CBT#BC0 implements Arm TrustZone for Armv8-M to isolate secure and non-secure firmware execution domains, with dedicated secure boot ROM and key management unit (KMU). Its system clock tree includes an on-chip FLL, PLL, and multiple independent clock sources (HOCO, MOCO, LOCO, IWDTOSC) enabling dynamic power-state transitions.
Peripheral integration includes a 12-channel 12-bit SAR ADC with programmable gain amplifier (PGA), two 16-bit general-purpose timers with complementary PWM outputs, and a 4-channel DMA controller supporting memory-to-peripheral transfers without CPU intervention. All peripherals are accessible from both secure and non-secure worlds via configurable bus firewall registers.
