Overview
R7FS128782A01CLM#AC1 from Renesas is an Arm Cortex-M0+ microcontroller operating at up to 32 MHz, featuring 256 KB code flash, 24 KB SRAM, and integrated DALI, CTSU, USBFS, CAN, and 14-bit ADC - designed for lighting control, touch-enabled HMI, and industrial sensor nodes in -40°C to +85°C environments.
For engineers reviewing the R7FS128782A01CLM#AC1 datasheet, R7FS128782A01CLM#AC1 pinout, R7FS128782A01CLM#AC1 application, or R7FS128782A01CLM#AC1 equivalent, key selection considerations include its 36-pin LGA package, 10-channel ADC14, dual AGT timers, USB Battery Charging 1.2 compliance, and DALI 2 protocol support for digital lighting systems.
Technical Context
This MCU implements a single-core Arm Cortex-M0+ (Armv6-M, r0p1-00rel0) with MPU-based memory protection across 8 regions and supports multiple clock sources including HOCO (24–32 MHz), SOSC (32.768 kHz), and MOSC (1–20 MHz). It integrates dedicated hardware accelerators: CRC calculator with LSB/MSB selectable bit order, DOC for 16-bit arithmetic, and CAC for real-time clock accuracy validation.
The peripheral set includes three SCI modules (UART/IIC/SPI), two I2C buses, two SPI interfaces, one CAN 2.0B controller with 32 mailboxes, and a full-speed USBFS module with on-chip transceiver and 5-pipe endpoint architecture - all coordinated via ELC event linking and DTC data transfers without CPU intervention.
